Blackjack Side Bets Explained: 21+3, Perfect Pairs and Their Edges

The Infinite Blackjack rules file prints the main game's return at 99.47% and, a few lines lower, the 21+3 return at 96.30%. Same table, same shoe, but blackjack side bets like 21+3 cost about seven times more per unit wagered. That gap is the whole story, and this page measures it bet by bet from published returns.

Each side bet's house edge here is 100% minus the return its provider or rules file prints, and paytables appear exactly as those files state them. The figures cover the Evolution, Pragmatic Play Live, Playtech and OnAir tables dealt in Ontario, so the same bet name can be compared from one table to the next.

What blackjack side bets cost on a published rules file

A side bet is a second wager in a small circle beside the main box. It settles on the first cards dealt, before you make a decision, and pays from its own paytable. The main hand rewards decisions; the side bet rewards a card pattern. That difference is why blackjack side bets cannot be lowered by strategy.

The house edge of a side bet works like the edge on any wager: 100% minus the published return. If a rules file says a bet returns 96.30%, the house keeps 3.70% of every dollar staked on it over the long run. Single sessions swing wildly around that figure, because side bets pay rarely and pay big when they do.

The cleanest single source is Evolution’s Infinite Blackjack rules file, for a table dealt at five Ontario sites. It publishes a return for the main game and for each of its four side bets on one page. The same provider’s Power Blackjack file does the same, and the rest of the figures below come from each provider’s own rules.

Read the table top to bottom and the pattern is plain. The cheapest side bet on this table costs about seven times the main hand per dollar, and the dearest costs about eleven times as much. None of these blackjack side bets comes close to the 0.53% the main game gives up when you play basic strategy for every hand.

These figures belong to one table. Another provider, or another game from the same provider, can run a bet with the same name on a different paytable, and a different paytable means a different edge. The second table below shows how far the same four names move across Evolution’s own games. Names travel between tables; prices do not.

How the 21+3 side bet pays

21+3 takes your first two cards and the dealer’s face-up card and treats them as a three-card poker hand. If the three cards form a qualifying hand, the bet pays. The Infinite Blackjack paytable prints five payout levels: 100:1 at the top, then 40:1, 30:1, 10:1 and 5:1. Anything that does not qualify loses the stake.

The published return for 21+3 on Infinite Blackjack is 96.30%, so the house edge is 3.70%. Evolution’s classic and Speed tables, Pragmatic’s ONE Blackjack, Speed and Blackjack X, and OnAir’s seven-seat tables all print the same 96.30%. That is still about seven times the main game’s 0.53%, on every round you place it.

The figure moves on other games. Power Blackjack’s 21+3 returns 96.09% and Infinite Fun Fun 21’s returns 97.53%, an edge of 2.47%. Playtech’s All Bets Blackjack, dealt at 888casino, Betway, LeoVegas and ToonieBet, prints the same 100 to 5:1 ladder, and its six side bets return between 93.89% and 96.30%.

Perfect Pairs and Any Pair: betting on your first two cards

Pair bets settle on your first two cards alone. Evolution’s Any Pair on Infinite Blackjack pays 25:1 when the two cards form a suited pair and 8:1 for any other pair, with a published return of 95.90%, a house edge of 4.10%. On Power Blackjack the same Any Pair bet returns 96.58%, an edge of 3.42%.

Perfect Pairs is the more common name. Evolution’s classic and Speed tables and Pragmatic’s ONE Blackjack, Speed and Blackjack X print 95.90% for it, a 4.10% edge. OnAir’s seven-seat tables quote the same 95.90% with a top payout of 25:1. Infinite Fun Fun 21 runs a pair-style Match bet at 97.01%.

The dearer versions sit on other tables. Perfect Pairs on Evolution’s Always 6 Blackjack, dealt at ToonieBet, returns 93.89%, a 6.11% edge, so the same name costs half again as much as on the classic table. Playtech’s All Bets Blackjack splits the idea in two, a Perfect Player Pair and a Perfect Dealer Pair, each paying 25:1, 12:1 and 6:1.

Hot 3 and Bust It: totals and dealer busts

Hot 3 adds your first two cards to the dealer’s face-up card and pays on the total. On Infinite Blackjack the top line is three sevens at 100:1, the bottom line a total of 19 at 1:1. The rules file publishes a return of 94.60%, so the edge is 5.40%, roughly ten times the main hand.

Bust It is a bet on the dealer. It pays when the dealer busts, and the payout climbs with the number of cards the dealer drew: 1:1 for three cards up to 250:1 for eight or more. It pushes if you have blackjack. The published return is 94.12%, an edge of 5.88%, the highest of the four.

Both bets run on more than one Evolution table, at very different prices. Bust It returns 94.71% on Power Blackjack, 98.15% on Infinite Fun Fun 21 and 93.81% on Easy Blackjack, dealt at Casino Days and LeoVegas. Hot 3 returns 96.21% on Power Blackjack and 97.14% on Fun Fun 21. Pragmatic’s ONE Blackjack runs its own dealer-bust bet at 94.12%.

Insurance is a side bet too

Insurance is offered when the dealer shows an Ace, and it settles on whether the dealer has blackjack. It is separate from your hand, which makes it a side bet in all but name. On a six-deck shoe, counting no cards already seen, insurance at 2:1 returns about 92.60%. That is a house edge of 7.40%.

That figure is higher than every side bet in the Infinite table above. Insurance feels like protection for a good hand, but it is a separate wager on the dealer’s hole card, and basic strategy declines it. On Infinite Blackjack the dealer peeks only with an Ace up, and with a ten-value card showing there is no insurance at all.

Lightning Blackjack adds another reason to decline. Its rules file says that taking insurance forfeits both the Lightning fee and the multiplier on that round. You pay for insurance twice there: once in the edge built into the insurance bet itself, and again in losing what the fee had bought.

Side bets with the biggest top payouts

The bets with the largest top lines are rarely the cheapest. Pragmatic’s Crazy 7 on ONE Blackjack pays up to 2,000 to 1 for three suited sevens and returns 94.77%, a 5.23% edge. Lucky Ladies on Evolution’s Always 6 tables tops out at 200 to 1 and returns 91.42%, an edge of 8.58%.

Playtech’s All Bets Blackjack prints Top 3 at 270:1, 180:1 and 90:1, Buster Blackjack up to 2,000:1 and Lucky Lucky up to 200:1, within its 93.89% to 96.30% range. Evolution’s Bust It reaches 250:1 on Infinite Blackjack while returning 94.12%, the dearest of that table’s four side bets. Each top line is a long shot, priced into the return.

A large top payout tells you little about the price. A 2,000:1 line can sit on a bet with a high edge, because the chance of hitting it is tiny and the lower lines pay little. Rank these bets by their published return, never by the top line, and compare each with the main hand’s edge on the same table.

Side bets per round: an illustrative example

The cost of a side bet scales with how often you place it. Expected loss is stake × house edge, every round. The example below uses round figures chosen for illustration; it describes a long-run average across many rounds, not the result of any session, and actual outcomes swing far above and below it.

Example only: a C$10 main bet on Infinite Blackjack costs about C$0.05 per round on average at 0.53%. Add a C$5 21+3 bet at 3.70% and that side bet alone costs about C$0.19 per round. Over 50 rounds the main hand averages about C$2.65 and the side bet about C$9.25.

The side bet is half the stake and more than three times the cost. Swap 21+3 for Bust It at 5.88% and the side bet averages about C$14.70 over the same 50 rounds. These are averages, and a single large payout can mask the cost for a while, but the arithmetic catches up over enough rounds.

Checks before placing a side bet

Open the table’s help screen and find the return figure next to each side bet. Subtract it from 100% and compare the result with the main game’s edge. Then compare it with the figures on this page: a 21+3 at 96.30% or a Perfect Pairs at 95.90% matches the common Evolution and Pragmatic paytables.

Then check the paytable on the screen against the figures here. A bet called 21+3 or Perfect Pairs can carry different payouts from one provider to the next, and a lower top line changes the edge. If the paytable differs from the one printed here, rely on the return printed in that game’s own help screen.

Questions at the table

Frequently asked questions

What are blackjack side bets?

Side bets are optional wagers placed alongside the main hand, usually in small circles on the layout. They settle on a specific event, such as your first two cards forming a pair or the dealer busting, and they pay from their own paytable. They are separate from the main bet and carry their own, higher house edge.

What is the 21+3 side bet in blackjack?

21+3 combines your first two cards with the dealer's face-up card into a three-card poker hand and pays if that hand qualifies. On Evolution's Infinite Blackjack the paytable runs from 100:1 down to 5:1, and the rules file publishes a return of 96.30%. That is a house edge of 3.70%, against 0.53% on the main hand.

What is the house edge on Perfect Pairs?

It depends on the paytable. Evolution's and Pragmatic Play's live tables publish 95.90% for Perfect Pairs, a house edge of 4.10%. The version on Evolution's Always 6 tables returns 93.89%, an edge of 6.11%, so the same name can cost half again as much.

Are blackjack side bets worth it?

On the published figures, every side bet costs more per dollar than the main hand. On Infinite Blackjack the main game gives up 0.53% while the four side bets give up between 3.70% and 5.88%. Some players accept that price for the occasional large payout; the long-run cost is still several times higher.

What is the Bust It side bet?

Bust It pays when the dealer busts, and the payout grows with the number of cards the dealer drew, from 1:1 for three cards to 250:1 for eight or more on Infinite Blackjack. It pushes if you have blackjack. The return is 94.12% there, 94.71% on Power Blackjack and 98.15% on Infinite Fun Fun 21.

What is Hot 3 in blackjack?

Hot 3 settles on the total of your first two cards plus the dealer's face-up card. On Infinite Blackjack the top line is three sevens at 100:1 and the bottom line a total of 19 at 1:1. The return is 94.60% there, 96.21% on Power Blackjack and 97.14% on Infinite Fun Fun 21.

Is insurance a side bet?

In effect, yes. Insurance is an extra wager that the dealer has blackjack when an Ace shows, and it settles separately from your hand. On a six-deck shoe, insurance at 2:1 returns about 92.60%, a house edge of 7.40%, and about 7.47% on eight decks, higher than almost every side bet measured on this page.

Do side bets affect basic strategy?

No. The side bet settles on the first cards dealt, before you make any decision, so the correct play for the main hand stays exactly the same. Basic strategy for the main hand depends only on the table rules. On Lightning Blackjack, taking insurance also forfeits the fee and multiplier, which is one more reason to decline it.

Which blackjack side bet has the lowest house edge?

Bust It on Evolution's Infinite Fun Fun 21 returns 98.15%, a house edge of 1.85%, the lowest in our records. The same table's 21+3 returns 97.53% and Hot 3 97.14%. On standard Evolution and Pragmatic tables, 21+3 at 96.30% is the cheapest common choice, with a 3.70% edge.

Does a side bet change the house edge on the main hand?

No. The two wagers settle separately, so the main hand keeps its own edge, 0.53% on Infinite Blackjack, whatever you place in the side circle. What changes is the cost of the whole round, because the side bet adds its own higher edge on top. The bigger the side stake, the more the round costs on average.
