Why Blackjack Variants Matter
Walk into any major Australian casino or fire up an online blackjack lobby, and you will be confronted with a dizzying array of choices. Classic Blackjack, Pontoon, Spanish 21, Lightning Blackjack, Infinite Blackjack — the list goes on. While they all share the same core objective (beat the dealer without going over 21), the devil is in the details.
Different variants mean different rules, and different rules mean different house edges. A seemingly minor rule change — like removing the 10-value cards from the deck in Spanish 21, or allowing you to swap cards between hands in Blackjack Switch — can dramatically shift the odds in either direction.
Understanding variants matters for three reasons:
- House edge variation: The difference between the best and worst blackjack variants can be over 2%. Over hundreds of hands, that is a significant amount of money.
- Strategy differences: Basic strategy is not universal. The correct play in Classic Blackjack may be the wrong play in Spanish 21 or Pontoon. Using the wrong strategy in the wrong game costs you money.
- Entertainment value: Some variants offer bonus payouts, side bets and unique mechanics that make the game more exciting — even if the maths is slightly less favourable.
This guide covers every major variant you will encounter as an Australian player, with honest analysis of the house edge, strategy adjustments and our recommendation on who each game is best suited for.

Classic / American Blackjack
Classic Blackjack (also called American Blackjack) is the gold standard and the version most people think of when they hear the word "blackjack." If you are going to learn one variant properly, this is the one. It is the foundation upon which all other variants are built.
Rules Overview
Classic Blackjack is typically played with 6 or 8 decks in a shoe. The dealer receives two cards — one face up and one face down (the hole card). If the dealer's upcard is an Ace or a 10-value card, they check the hole card for blackjack before players act. This is the defining feature of American-style blackjack: the dealer peeks.
Players can hit, stand, double down (usually on any two cards), split pairs (typically up to 3 or 4 hands), and sometimes surrender. The dealer must stand on all 17s at some tables, or hit soft 17 at others. A natural blackjack pays 3:2.
House Edge
With optimal basic strategy and favourable rules, the house edge sits between 0.4% and 0.6%. This makes Classic Blackjack one of the best-value games in any casino. The exact edge depends on specific table rules — number of decks, whether the dealer hits or stands on soft 17, doubling restrictions and surrender availability all play a role.
Strategy Tips
Standard basic strategy charts are designed specifically for Classic Blackjack. Memorise the chart and you will be playing near-optimally. The key advantage of the peek rule is that you never have to worry about losing your doubled or split bets to a dealer blackjack — if the dealer has it, the round ends before you have the chance to increase your wager.
Who Should Play
Everyone. This is the perfect starting point for beginners and the variant most experienced players keep coming back to. If you want the purest blackjack experience with the most favourable maths, Classic Blackjack is your game.
European Blackjack
European Blackjack is the standard variant you will find across Europe and in many international online casinos. It plays similarly to Classic Blackjack with one crucial difference: there is no hole card.
Rules Overview
In European Blackjack, the dealer takes only one card face up during the initial deal. The second card is not dealt until all players have completed their hands. This is known as the European No Hole Card (ENHC) rule. The game is typically played with 2 to 8 decks, and the dealer stands on all 17s.
Doubling down is often restricted to hard totals of 9, 10 or 11 (though this varies). Splitting is usually limited to one split (creating two hands), and you cannot double after splitting. These restrictions increase the house edge slightly compared to Classic Blackjack.
The ENHC Catch
The major strategic implication of the no-hole-card rule is this: if you double down or split, and the dealer subsequently makes a blackjack, you lose all your additional bets. In Classic Blackjack, the dealer would have already checked for blackjack and ended the round. Under ENHC, you need to be more cautious about doubling and splitting against a dealer 10 or Ace.
This is where variants like BB+1 and OBBO (common in Australia) come in. These rules return your additional bets if the dealer has blackjack, combining the no-hole-card dealing style with the player protection of the American version.
House Edge
The house edge for European Blackjack ranges from 0.4% to 0.7%, depending on the specific rules. The restricted doubling and splitting options typically make it slightly less favourable than a liberal Classic Blackjack game.
Who Should Play
European Blackjack is fine for players who understand the strategic adjustments needed for the no-hole-card rule. If you are used to Classic Blackjack, just remember to be more conservative when the dealer shows a 10 or Ace. It is widely available online and a perfectly acceptable variant to play.
Atlantic City Blackjack
Atlantic City Blackjack is named after the famous gambling destination in New Jersey and is known for having some of the most player-friendly rules in the game. It is one of the best variants you can find if you want to minimise the house edge.
Rules Overview
Played with 8 decks. The dealer stands on all 17s, including soft 17 (S17). Players can double down on any two cards. Doubling after splitting (DAS) is allowed. Players can split up to 3 times (creating 4 hands). Late surrender is available — this is the big one, as surrender is not offered in many other variants. The dealer peeks for blackjack (OBO rule).
House Edge
With all these player-friendly rules, the house edge for Atlantic City Blackjack is approximately 0.35% to 0.40% with optimal strategy. That is about as good as it gets in blackjack without counting cards. The combination of late surrender, S17 and liberal doubling/splitting rules makes this a mathematically excellent game.
Strategy Tips
Standard basic strategy applies, but you should also memorise the surrender plays. Surrender 16 against dealer 9, 10, or Ace. Surrender 15 against dealer 10. These surrender plays alone save you a meaningful fraction of a percent over the long run. Do not skip them — that is the whole point of playing this variant.
Who Should Play
Anyone who is serious about minimising the house edge. Atlantic City Blackjack is an excellent choice for strategy-minded players. It is available at many online casinos, and if you spot it in the lobby, it should be near the top of your list.
Vegas Strip Blackjack
Vegas Strip Blackjack is the variant you will find at most casinos on the Las Vegas Strip. It has become widely available online and offers a slightly different flavour from both Classic and Atlantic City Blackjack.
Rules Overview
Played with 4 decks (fewer than most other variants). The dealer stands on all 17s (S17). Players can double on any two cards. Splitting is allowed up to 4 hands. Doubling after splitting is permitted. The dealer peeks for blackjack. Aces can only be split once, and split Aces receive only one card each.
House Edge
The house edge is approximately 0.35% with optimal play. The 4-deck shoe is a significant advantage compared to 6 or 8-deck games, as fewer decks slightly favour the player. Combined with the liberal rules, Vegas Strip is one of the best variants available.
Strategy Tips
Basic strategy for a 4-deck game differs slightly from a 6 or 8-deck strategy, particularly in doubling situations. With fewer decks, doubling down on soft hands and splitting pairs becomes slightly more favourable. Make sure you are using the correct strategy chart for a 4-deck game to get the full benefit.
Who Should Play
Vegas Strip Blackjack is great for all experience levels. The 4-deck shoe and solid rules make it one of the better variants you will find online. If you cannot find Atlantic City Blackjack, Vegas Strip is an excellent alternative.
Spanish 21
Spanish 21 is one of the most exciting blackjack variants around, and it throws a major spanner in the works: all four 10-value cards are removed from each deck. That is right — the 10 of hearts, diamonds, clubs and spades are gone, leaving you with a 48-card deck per standard deck used. Jacks, Queens and Kings remain.
Rules Overview
Played with 6 or 8 Spanish decks (48 cards each). Player blackjack always beats dealer blackjack. Player 21 always wins (it does not push). Late surrender is available, even after doubling. Players can double on any number of cards, not just the first two. Re-doubling is allowed (you can double, then double again). The dealer may hit or stand on soft 17, depending on the table.
Bonus Payouts
Spanish 21 offers bonus payouts for specific hands, which partially compensate for the missing 10s:
| Hand | Payout |
|---|---|
| 5-card 21 | 3:2 |
| 6-card 21 | 2:1 |
| 7+ card 21 | 3:1 |
| 6-7-8 mixed suits | 3:2 |
| 6-7-8 same suit | 2:1 |
| 6-7-8 all spades | 3:1 |
| 7-7-7 mixed suits | 3:2 |
| 7-7-7 same suit | 2:1 |
| 7-7-7 all spades | 3:1 |
| 7-7-7 suited (dealer shows 7) | $1,000–$5,000 bonus |
House Edge
Despite the missing 10s (which significantly disadvantage the player), the bonus payouts and extremely liberal rules bring the house edge back to approximately 0.4% to 0.8%, depending on whether the dealer hits or stands on soft 17. With the S17 rule, the house edge is about 0.4%, which is competitive with Classic Blackjack.
Strategy Tips
Spanish 21 requires its own dedicated basic strategy chart. Do not use standard blackjack strategy — the removal of the 10s changes every calculation. Key differences include being more aggressive with doubling (since you can double on any number of cards and even re-double), and the fact that you should never stand on a soft total below 18. The late surrender after doubling option is extremely valuable and should be used when the situation calls for it.
Who Should Play
Spanish 21 is ideal for players who want more action and excitement than Classic Blackjack. The bonus payouts add a thrill that standard blackjack lacks. However, you need to invest time learning the unique strategy. If you are willing to put in that effort, it is a rewarding variant with a competitive house edge.
Pontoon
Pontoon holds a special place in Australian gambling culture. For many Aussies, Pontoon was the first card game they learned around the kitchen table, long before they ever set foot in a casino. The casino version formalises the rules and adds the house edge, but it retains that familiar, distinctly Australian feel.
Origins and Cultural Significance
Pontoon evolved from the British card game of the same name, which itself descended from the French game "Vingt-et-Un" (twenty-one). The game spread through the British Empire and took on a life of its own in Australia, where it became a staple of home card games, pub nights and military barracks. If you grew up in Australia, there is a fair chance your grandad taught you Pontoon before you could tie your own shoelaces.
The casino version of Pontoon (also sometimes called "Australian Pontoon") differs from the informal home game but preserves the core mechanics and terminology that make it uniquely Antipodean.
Rules Overview
Pontoon is typically played with 8 decks. The most significant difference from standard blackjack is that both of the dealer's cards are face down. You cannot see either of the dealer's cards, which makes every decision a bit more of a gamble.
Key rules and terminology:
| Pontoon Term | Blackjack Equivalent | Details |
|---|---|---|
| Pontoon | Natural Blackjack | Ace + 10-value card. Pays 2:1 (better than the 3:2 in standard blackjack). |
| Twist | Hit | Request an additional card. |
| Stick | Stand | Keep your current hand. You can only stick on 15 or higher. |
| Buy | Double Down | Double your bet and receive one more card. Can be done on any hand of 2, 3 or 4 cards. |
| Split | Split | Divide a pair into two hands. Re-splitting is usually not allowed. |
| Five Card Trick | No equivalent | A hand of 5 or more cards totalling 21 or under. Beats everything except a Pontoon. Pays 2:1. |
Key Rule Differences from Standard Blackjack
- Both dealer cards face down: This is the defining feature. You have zero information about the dealer's hand, making decisions harder.
- Must twist on 14 or below: You cannot stick on a total of 14 or less. You must keep taking cards.
- Pontoon pays 2:1: A natural (Ace + 10-value) pays 2:1 instead of 3:2, which is actually better for the player.
- Five Card Trick pays 2:1: Getting 5 cards without busting is a powerful hand that beats any dealer hand except a Pontoon.
- Dealer wins ties: In a push, the dealer wins. This is a significant disadvantage for the player and is the main source of the house edge.
- No surrender: Surrender is not an option in Pontoon.
- Buying on multiple cards: You can buy (double) on hands of 2, 3 or 4 cards, not just on the first two. This is very player-friendly.
House Edge
The house edge for Pontoon is approximately 0.4% to 0.6% with optimal strategy. The "dealer wins ties" rule is harsh, but it is offset by the 2:1 Pontoon payout, the Five Card Trick bonus and the ability to buy on multiple cards. The end result is a house edge that is competitive with Classic Blackjack.
Strategy Tips
Pontoon strategy differs significantly from standard blackjack because you have no information about the dealer's hand. Key strategy points include:
- Always twist on 14 or below (you have to anyway).
- Stick on hard 15 against the unknown dealer hand — but only when the Five Card Trick is not achievable.
- Aggressively pursue the Five Card Trick when you have 4 cards totalling 15 or less. The 2:1 payout makes it highly valuable.
- Buy (double) more liberally than in standard blackjack, especially with soft hands, because you can buy on 3 or 4 card hands.
- Always split Aces and 8s, just like standard blackjack.
Who Should Play
Pontoon is perfect for Australian players who want something that feels familiar and culturally relevant. It is more exciting than Classic Blackjack due to the hidden dealer cards and the Five Card Trick mechanic. The strategy is more complex because you are flying blind on the dealer's hand, so it suits players with some experience who enjoy a challenge. If you grew up playing Pontoon at home, the casino version will feel like coming home.
Blackjack Switch
Blackjack Switch is one of the cleverest blackjack variants ever devised. The premise is simple: you play two hands simultaneously and can swap the second card between your two hands to create better starting hands. It sounds like cheating, but it is a legitimate game with rules that balance out this massive player advantage.
Rules Overview
You must place two equal bets and receive two hands. After the initial deal, you can switch the top cards between your two hands. For example, if hand one is 5-10 and hand two is 10-6, you could switch to make 5-6 (11, perfect for doubling) and 10-10 (20). That is a dramatic improvement from two mediocre hands to two strong ones.
To compensate for this advantage, the casino makes two key rule changes:
- Blackjack pays even money (1:1): Not 3:2. This is a significant cost.
- Dealer 22 pushes against all hands except natural blackjack: Instead of busting on 22, the dealer pushes. This is called the "Super Match" or "Push 22" rule and it is a meaningful shift in the house edge.
House Edge
Despite the trade-offs, the house edge for Blackjack Switch is approximately 0.17% with optimal play. That is one of the lowest house edges in any casino game, making it extremely attractive for mathematically minded players. The switching mechanic is so powerful that even with the 1:1 blackjack payout and the Push 22 rule, the game still favours the player more than almost any other variant.
Strategy Tips
The strategy for Blackjack Switch is complex because you need to evaluate the best combination of two hands before and after switching, considering every possible permutation. Online strategy calculators are available and highly recommended. Key principles include always switching to create a 21 or 20, and avoiding switches that merely improve one hand at the expense of the other. Both hands matter equally.
Who Should Play
Blackjack Switch is ideal for experienced players who enjoy the strategic depth of managing two hands simultaneously. The ultra-low house edge makes it one of the best-value variants available. If you can find it online or at a live casino, it is well worth your time. Be warned: the strategy is not simple, and playing without a solid understanding of when to switch will cost you.
Double Exposure Blackjack
Double Exposure Blackjack (also known as "Face Up 21") flips the script entirely: both of the dealer's cards are dealt face up. You can see everything. It sounds like a dream, but the casino compensates with several rule changes that claw back the advantage.
Rules Overview
Played with 6 or 8 decks. Both dealer cards are visible from the start. To offset this enormous informational advantage for the player, the following rules apply:
- Dealer wins all ties (except a tied natural blackjack, which the player wins).
- Blackjack pays even money (1:1) instead of 3:2.
- Doubling is usually restricted to hard totals of 9, 10 or 11.
- No surrender is typically available.
- No insurance is offered (it would be unnecessary since you can see both cards).
House Edge
The house edge for Double Exposure is approximately 0.7% with optimal strategy. This is higher than Classic Blackjack because the "dealer wins ties" rule is extremely costly. In a standard game, roughly 8% of hands are pushes. Converting all of those to dealer wins adds substantially to the house edge.
Strategy Tips
Double Exposure requires a unique strategy because knowing both dealer cards changes every decision. You should hit on hard totals that you would normally stand on when you can see the dealer has a strong total. Conversely, you can stand more often when the dealer shows a weak total. Standard basic strategy does not apply — you need a Double Exposure-specific chart.
Who Should Play
Double Exposure is interesting for beginners who want to learn dealer behaviour, as seeing both cards helps you understand dealer outcomes. However, the higher house edge and loss of pushes make it less attractive for serious players. It is a fun variant for casual play but not optimal for grinding.
Perfect Pairs Blackjack
Perfect Pairs is not really a separate variant so much as a standard blackjack game with an additional side bet. It is one of the most popular side bet options at both land-based and online casinos, and you will encounter it regularly in Australia.
Rules Overview
The base game follows standard blackjack rules (Classic or European, depending on the casino). Before the deal, you have the option to place an additional side bet on whether your first two cards will form a pair. There are three types of pairs:
| Pair Type | Description | Typical Payout |
|---|---|---|
| Perfect Pair | Same rank and same suit (e.g., two Queen of Hearts) | 25:1 |
| Coloured Pair | Same rank and same colour, different suit (e.g., 7 of Hearts + 7 of Diamonds) | 12:1 |
| Mixed Pair | Same rank, different colour (e.g., Jack of Spades + Jack of Diamonds) | 6:1 |
House Edge
The base blackjack game has its normal house edge (0.4%–0.6%). However, the Perfect Pairs side bet carries a house edge of approximately 4% to 6%, depending on the number of decks and specific payouts. This makes it a bad bet from a purely mathematical standpoint. The side bet is where the casino makes its money on this variant.
Who Should Play
If you enjoy the excitement of side bets and do not mind paying a premium for it, Perfect Pairs adds fun to your session. Just be aware that the side bet has a high house edge. Our recommendation: play the base game with optimal strategy and treat the Perfect Pairs bet as occasional entertainment, not a core part of your strategy. Never bet the side bet as a significant portion of your bankroll.
Infinite Blackjack
Infinite Blackjack is a live dealer game created by Evolution Gaming that solves one of the biggest problems with live blackjack: limited seats. In traditional live blackjack, each table accommodates only 7 players. In Infinite Blackjack, an unlimited number of players can play the same hand simultaneously.
How It Works
Every player receives the same initial two cards. The dealer also receives the same initial cards. However, from the point of the first decision onwards, each player plays independently. One player might hit while another stands. The dealer plays their hand against every player individually. This means the game can accommodate hundreds or even thousands of simultaneous players.
Rules Overview
Played with 8 decks. The dealer stands on soft 17. Six Card Charlie is in play — reaching 6 cards without busting is an automatic win. Free splits and free doubles are offered on certain hands (the casino absorbs the additional bet). Four side bets are available: Any Pair, 21+3, Hot 3 and Bust It.
House Edge
The base game house edge is approximately 0.5%, which is solid and competitive with Classic Blackjack. The side bets carry higher house edges (typically 3% to 10% depending on the specific bet), so stick to the base game for the best value.
Who Should Play
Infinite Blackjack is perfect for players who want the live dealer experience without waiting for a seat. It is always available, the limits are typically low (starting from $1 at many casinos), and the rules are player-friendly. The downside is that you lose some of the intimate table atmosphere of a 7-player game. But for accessibility and convenience, it cannot be beaten.
Lightning Blackjack
Lightning Blackjack is another Evolution Gaming creation that adds their signature "Lightning" mechanic to the blackjack formula. If you have played Lightning Roulette or Lightning Baccarat, you know what to expect: random multipliers on winning hands.
How It Works
After placing your bet, a "Lightning fee" is automatically deducted (essentially a 100% surcharge on your base bet, meaning you effectively bet double). In return, random multipliers between 2x and 25x are assigned to specific card values each round. If your winning hand total corresponds to one of the Lightning numbers, your payout is multiplied accordingly.
For example, if 19 is assigned a 5x multiplier and you win with a total of 19, your payout is 5x instead of 1:1. The dream scenario is winning a natural blackjack with a high multiplier for a massive payout.
Rules Overview
Played with 8 decks in a live dealer format. Standard blackjack rules apply for the base game (hit, stand, double, split). The dealer hits on soft 17. Natural blackjack pays 3:2 before the multiplier is applied. The lightning fee effectively doubles the cost of each hand.
House Edge
The house edge is approximately 1.1%, which is higher than Classic Blackjack due to the Lightning fee structure. However, the potential for multiplied payouts means that individual sessions can be highly volatile. You can win big or lose more quickly than in standard blackjack.
Who Should Play
Lightning Blackjack is designed for players who enjoy high volatility and the thrill of potentially massive payouts. It is an entertainment-focused variant rather than a grinder's game. If you play blackjack for the excitement and do not mind a higher house edge in exchange for the chance at multiplied wins, Lightning Blackjack delivers. If you are a purist focused on minimising the house edge, stick with Classic or Atlantic City Blackjack.
Free Bet Blackjack
Free Bet Blackjack, created by Geoff Hall (the same designer behind Blackjack Switch), offers something that sounds too good to be true: the casino pays for your doubles and splits. There is a catch, of course, but the mechanic is genuinely exciting.
How It Works
When you have a hard total of 9, 10 or 11, you can double down for free — the casino places the additional bet for you. If you win, you get paid as though you had doubled your own money. If you lose, you only lose your original bet. Similarly, non-10-value pairs can be split for free, with the casino covering the second bet.
The trade-off: if the dealer busts with a total of 22, all remaining bets push (except natural blackjacks, which still win). This "Push 22" rule is the same one used in Blackjack Switch and it is the primary mechanism by which the casino recoups the cost of the free bets.
House Edge
The house edge is approximately 1.0% with optimal strategy. This is higher than Classic Blackjack, but the free doubles and splits make the game significantly more exciting. You get to make aggressive plays without risking extra money, which is a unique and appealing proposition.
Strategy Tips
Always accept the free double when offered (hard 9, 10 or 11). Always accept the free split when offered (non-10-value pairs). Since these bets cost you nothing, there is no mathematical reason to decline them. The Push 22 rule means you should adjust your strategy slightly — the dealer busting on 22 no longer helps you, so hands that relied on dealer busts are slightly weaker.
Who Should Play
Free Bet Blackjack is excellent for players who love doubling and splitting but hate the risk of losing extra money. It is a more action-packed experience than Classic Blackjack and the free bets generate plenty of excitement. The slightly higher house edge is a reasonable trade-off for the reduced risk on aggressive plays. Widely available as both an RNG game and a live dealer game.
Progressive Blackjack
Progressive Blackjack adds a side bet that feeds into a progressive jackpot, giving you the chance to win a life-changing sum of money on a single hand. The base game is standard blackjack; the progressive element is an optional side bet.
How It Works
Before each hand, you can place a small side bet (typically $1 to $5) that contributes to the progressive jackpot pool. The jackpot is won by being dealt specific high-value hands, usually involving suited Aces. A typical payout structure might look like this:
| Hand | Payout |
|---|---|
| 4 suited Aces | 100% of progressive jackpot |
| 4 unsuited Aces | Mini jackpot or fixed amount |
| 3 suited Aces | $500–$5,000 (varies) |
| 2 suited Aces | $50–$100 |
| Any pair of Aces | $10–$25 |
House Edge
The base blackjack game has its normal house edge. However, the progressive side bet carries a house edge of approximately 5% to 20%, depending on the current jackpot size and the specific pay table. Like all progressive jackpot games, the side bet only becomes theoretically positive when the jackpot reaches an extremely high amount — and even then, the variance is enormous.
Who Should Play
Progressive Blackjack is for players who enjoy the lottery-style thrill of chasing a big jackpot. If you are going to play, treat the side bet as pure entertainment and never rely on it as a serious strategy. Play the base game with proper basic strategy and think of the progressive bet as buying a very expensive lottery ticket. Our advice: skip the side bet unless the jackpot is exceptionally high and you have the bankroll to absorb the cost.
Which Variant Should You Play?
Choosing the right blackjack variant depends on your experience level, risk tolerance and what you want out of the game. Here is our honest recommendation:
For Absolute Beginners
Start with Classic / American Blackjack
It has the simplest rules, the widest availability, and the most strategy resources. Learn basic strategy for Classic Blackjack first, and every other variant will be easier to pick up. Infinite Blackjack is also excellent because it is always available at low stakes and you can play at your own pace.
For Strategy-Focused Players
Try Atlantic City, Vegas Strip or Blackjack Switch
If minimising the house edge is your priority, these variants offer the best mathematical value. Atlantic City's late surrender and Vegas Strip's 4-deck shoe are both excellent. Blackjack Switch's 0.17% house edge is the gold standard, but requires learning a complex switching strategy.
For Action and Excitement Seekers
Go for Spanish 21, Lightning Blackjack or Free Bet Blackjack
These variants offer bonus payouts, multipliers and free bets that make every hand more thrilling. The house edge is slightly higher, but the entertainment value is significantly greater. Just make sure you are using the correct strategy for each variant.
For Australian Culture Enthusiasts
Pontoon is your game
It is the most uniquely Australian variant, with a competitive house edge and genuinely different gameplay. The hidden dealer cards and Five Card Trick mechanic make it exciting and challenging. If you grew up playing Pontoon at home, the casino version is a natural progression.
Side Bets Explained
Side bets are optional wagers you can place alongside your main blackjack bet. They offer the chance for bigger payouts on specific outcomes but always carry a higher house edge than the base game. Here are the most common side bets you will encounter:
Perfect Pairs
Bet on whether your first two cards form a pair. Perfect pairs (same suit) pay 25:1, coloured pairs (same colour) pay 12:1, and mixed pairs pay 6:1. House edge: approximately 4%–6%. Available at most online casinos and many Australian land-based tables.
21+3
This side bet combines your first two cards with the dealer's upcard to form a three-card poker hand. Payouts vary by hand:
| Hand | Typical Payout |
|---|---|
| Suited Three of a Kind | 100:1 |
| Straight Flush | 40:1 |
| Three of a Kind | 30:1 |
| Straight | 10:1 |
| Flush | 5:1 |
House edge: approximately 3%–5%. This is one of the more popular side bets because the payouts are attractive and the hit rate is reasonable.
Lucky Ladies
Bet on your first two cards totalling 20. The top payout is for two Queen of Hearts when the dealer has blackjack, which typically pays 1,000:1. A matched 20 (same rank and suit) pays 25:1, a suited 20 pays 10:1, and any 20 pays 4:1. House edge: approximately 5%–17% depending on the pay table. The house edge varies widely, so check the specific pay table before placing this bet.
Insurance
Technically a side bet, insurance is offered when the dealer shows an Ace. It pays 2:1 if the dealer has blackjack. House edge: approximately 7.4% (in a standard 6-deck game). As we discussed in our rules guide, insurance is almost always a bad bet unless you are counting cards. Decline it.
The Bottom Line on Side Bets
Every side bet in blackjack carries a significantly higher house edge than the base game. They are designed to be entertaining, not profitable. If you want to minimise your losses and play optimally, skip the side bets entirely. If you enjoy the excitement and treat them as an entertainment cost, that is perfectly fine — just do not make them a large proportion of your total wager.
Frequently Asked Questions
Classic / American Blackjack is the best starting point for beginners. The rules are straightforward, basic strategy charts are widely available, and it has one of the lowest house edges. Infinite Blackjack is also excellent because seats are always available and minimums start low. Once you are comfortable with the fundamentals, branch out to Spanish 21 or Free Bet Blackjack for more variety.
Blackjack Switch has the lowest house edge at approximately 0.17% with optimal play. Atlantic City Blackjack (0.35%) and Vegas Strip Blackjack (0.35%) are also excellent. Classic Blackjack with favourable rules (3:2, S17, DAS, late surrender) can get as low as 0.28%. The key is always finding the most player-friendly rules and playing with perfect basic strategy.
Yes, very much so. Pontoon has deep cultural roots in Australia and is one of the most recognisable card games in the country. Many Australians grew up playing informal versions of Pontoon at home. The casino version is widely available at Australian online casinos and some land-based venues. Its unique terminology (twist, stick, buy) and the Five Card Trick mechanic give it a distinctly Australian flavour.
Yes, each variant has its own optimal strategy. While the core principles of basic strategy carry over (always split Aces and 8s, never split 10s), the specific decisions for each hand change based on the rules. Using Classic Blackjack strategy in Spanish 21, for example, will cost you money. Fortunately, strategy charts and calculators are available online for every major variant. Take the time to study the correct strategy before playing a new variant with real money.
While both are blackjack variants, they are quite different. Pontoon uses a standard 52-card deck (times 8) and features hidden dealer cards and unique terminology. Spanish 21 removes all four 10-value cards from each deck but compensates with bonus payouts and extremely liberal rules. Pontoon has the Five Card Trick; Spanish 21 has multi-card bonus payouts. The dealer wins ties in Pontoon, while player 21 always wins in Spanish 21. They require completely different strategies.
From a pure maths perspective, no. Every side bet carries a significantly higher house edge (typically 3% to 15%+) compared to the base game (0.3% to 1%). However, side bets add excitement and the potential for large payouts on small wagers. If you treat them as entertainment and keep them as a small portion of your total betting, they are fine. Never make side bets a core part of your strategy or a large percentage of your wager.
Most of the variants listed in this guide are available at offshore online casinos that accept Australian players. Evolution Gaming's live dealer variants (Infinite, Lightning, Free Bet) are particularly widely available. Classic, European and Spanish 21 are standard at virtually every online casino. Pontoon is commonly found at casinos that cater to the Australian and UK markets. Always choose reputable, well-regulated casinos regardless of which variant you play.
In variants like Blackjack Switch and Free Bet Blackjack, if the dealer busts with exactly 22, all bets push (instead of the dealer losing). This is a significant rule because the dealer busts with 22 approximately 7% to 8% of the time. Converting all of those outcomes from player wins to pushes adds a substantial amount to the house edge. It is the primary mechanism the casino uses to offset the player-friendly rules in these games. The "Push 22" rule is estimated to add roughly 5% to 6% to the house edge, which is then offset by the free bets or switching mechanic.
