What Side Bets Are Actually For
Side bets serve a specific purpose for casinos — they generate significantly higher revenue per square foot than the main game. A blackjack table running at 0.5% house edge on the main bet generates modest theoretical hold per hand. Add a side bet running at 10% to 15% house edge on a $5 chip and the revenue picture changes substantially. Side bets are placed on every hand, resolved quickly and rarely given the same scrutiny players apply to the main game.
This does not mean all side bets are bad. Some are genuinely reasonable. But understanding that side bets are primarily a casino revenue tool — not a player opportunity — helps calibrate how much attention they deserve.
Blackjack Side Bets
21+3 — 3.23% to 13.39%
21+3 combines the player's two cards with the dealer's up card to form a three-card poker hand. A flush, straight, three of a kind or straight flush pays at varying rates. The house edge depends heavily on the pay table — it ranges from approximately 3.23% on favorable versions to 13.39% on poor ones. Always check what the specific table pays before betting. The most generous 21+3 pay tables are among the better blackjack side bets available.
Perfect Pairs — 2.03% to 11.25%
Perfect Pairs pays when the player's first two cards are a pair. Mixed pair, colored pair and perfect pair (same rank and suit) each pay at different rates. Again, the house edge is pay-table dependent and varies considerably. On the best pay tables it is a reasonable side bet. On standard tables it typically runs 6% to 11%.
Lucky Ladies — 17% to 25%
Lucky Ladies pays when the player's first two cards total 20. The top payout — two Queens of Hearts when the dealer has blackjack — can be substantial. The frequency of any qualifying total-20 hand keeps players interested. But the overall house edge typically runs 17% to 25% depending on pay table. The excitement of chasing the top payout masks expensive odds.
Three Card Poker Side Bets
Pair Plus — 7.28%
Pair Plus pays based solely on hand strength — pair, flush, straight, three of a kind or straight flush. At 7.28% house edge under the standard pay table it sits in the acceptable range for side bet entertainment. Pay table variation is significant — some versions run as low as 2.14% while others exceed 10%. The standard table game pay table of 40-30-6-4-1 produces the 7.28% figure most players encounter.
6-Card Bonus — 15%+
The 6-Card Bonus combines all six cards on the table into the best five-card poker hand. It sounds compelling — six cards to work with — but the house edge typically exceeds 15% and in some configurations reaches 26%. The bet is generally not worth placing.

Baccarat Side Bets
Dragon Bonus — 2.65% to 13.98%
Dragon Bonus pays when your chosen side wins by a margin — a natural win pays one rate, a natural with a tie another, and wins by various point margins pay progressively higher amounts. The house edge depends on which side you bet and the specific pay table. Banker Dragon Bonus typically runs around 9.37% and Player Dragon Bonus around 2.65% to 13.98% depending on configuration.
Perfect Pairs Baccarat — 10% to 15%
Pays when the first two cards on either side form a pair. Varies by casino and specific rules. Generally in the 10% to 15% house edge range — not worth regular betting.
The Side Bet Decision Framework
Use these guidelines when evaluating any side bet:
Under 5% house edge: Reasonable entertainment value — comparable to main game bets on many casino games.
5% to 15% house edge: Elevated cost. Acceptable for occasional entertainment if the payout excites you, but not a regular bet.
Above 15% house edge: Pure entertainment cost. Treat it the same as paying for a show — you are paying for the experience of watching the payout counter, not for a sound wager.
The Bottom Line
Side bets occupy a wide range of value. The Beat the Dealer Suited bet at 0.96% is genuinely player-friendly. The 21+3 at 3.23% on good pay tables is reasonable. Three Card Poker Pair Plus at 7.28% is acceptable entertainment. Beyond that the house edge climbs into territory where the bet is primarily a casino revenue mechanism rather than a competitive wager. Know the number before you put a chip on it.
