How it works
- Pick a side bet, then the pay table printed on your table (they vary more than the main game does).
- Set the number of decks and your stake.
- Every outcome is enumerated exactly from the shoe: chance, payout and what it contributes to the return.
- The result compares the side bet with the main blackjack bet at the same rules.
What the maths says
A side bet pays big on rare outcomes. The house edge is what is left after weighting every payout by its exact chance: sum of (payout × probability), minus the chance of losing. These are computed by enumerating every card combination in a fresh shoe, which is how side bets are rated; card counters can beat some of them, nobody else can.
Side bets usually cost far more than the main hand. With basic strategy the main bet costs 0.33% at standard six-deck rules; the cheapest side bet in the table above is still 3.24%, and the worst 24.71%.
The per-hour figures assume about 70 hands an hour, a typical pace at a full table; adjust your expectation to your own pace.
