Side bets โ sorted by house edge
Top of the table = least bad; bottom = avoid. Anything past ~5% edge drains the bankroll faster than the main game's ~0.5%, so the top-jackpot dream is rarely worth it.
| Side bet | House edge | RTP | Top payout | Verdict |
|---|---|---|---|---|
Perfect Pairs Player's first two cards form a pair โ mixed / coloured / perfect tiers pay 5:1 / 12:1 / 25:1. | 2.57โ4.10% | 95.90โ97.43% | 25:1 | Average |
21+3 Player two cards + dealer upcard form a 3-card poker hand (flush / straight / three-of-a-kind / straight-flush). | 3.24โ3.70% | 96.30โ96.76% | 100:1 | Average |
Suit 'Em Up Player's first two cards are suited (suited / blackjack / sevens pay progressively more). | 2.67โ4.65% | 95.35โ97.33% | 60:1 | Average |
Any Pair Player's first two cards form any pair (suited or not). | 4.10% | 95.90% | 25:1 | Average |
Lucky Lucky Player two cards + dealer upcard form 19/20/21 in various combinations. Suited 7-7-7 pays the top jackpot. | 2.63โ7.91% | 92.09โ97.37% | 200:1 | Average |
Hot 3 Player two cards + dealer upcard sum to 19, 20, or 21 โ pure totals, no card-combination logic. | 5.40โ5.65% | 94.35โ94.60% | 100:1 | Avoid |
Bust It Same idea as Buster โ but with a wider paytable and slightly worse expected return. | 5.83โ5.88% | 94.12โ94.17% | 250:1 | Avoid |
Buster Blackjack Pays when the dealer busts; size of the payout scales with how many cards it took to bust. | 5.74โ6.17% | 93.83โ94.26% | 2000:1 | Avoid |
Dealer Bust Flat 3:1 payout if the dealer busts. Looks tempting, isnโt โ the underlying frequency just doesnโt justify the price. | 6.18% | 93.82% | 3:1 | Avoid |
Top 3 Three-of-a-kind from the same hand as 21+3, paid as a separate higher-variance wager. | 3.50โ9.00% | 91.00โ96.50% | 270:1 | Average |
Royal Match Player's first two cards are suited (easy match) or specifically K+Q same suit (royal match). | 3.49โ10.14% | 89.86โ96.51% | 25:1 | Average |
Insurance Offered when the dealer shows an Ace โ pays 2:1 if the dealer has a ten-card hole. Mathematically a sucker bet for the basic-strategy player. | 7.40% | 92.60% | 2:1 | Avoid |
Over/Under 13 Side bet on whether the player's first two cards total over or under 13. Even money but with a chunky house edge baked in. | 6.55โ10.07% | 89.93โ93.45% | 1:1 | Avoid |
Super Sevens Player's first card is a 7, with cascading payouts up to three suited sevens. The top jackpot makes it look attractive โ the long-run drain doesn't. | 9.01โ12.61% | 87.39โ90.99% | 5000:1 | Avoid |
Lucky Ladies Player's first two cards total 20 โ escalating payouts for matched / suited / pair / Queen-of-Hearts pairs. | 5.87โ24.71% | 75.29โ94.13% | 1000:1 | Avoid |
