What the house keeps
Every casino bet has a built-in price: the long-run share of each stake the house expects to keep. Skill moves it in some games and not at all in others. These are the real figures.
| Bet | Relative size | House edge |
|---|---|---|
| Blackjack perfect basic strategy | ≈0.50% | |
| Baccarat Banker (5% commission) | 1.06% | |
| Baccarat Player | 1.24% | |
| Craps Pass line | 1.41% | |
| Roulette single zero, any even-money bet | 2.70% | |
| Roulette double zero, most bets | 5.26% | |
| Blackjack copying the dealer | ≈5.50% | |
| Baccarat Tie paying 8 to 1 | 14.36% |
Blackjack figures assume a six-deck shoe paying 3:2 on blackjack; exact numbers depend on the table rules. A 2.70% edge means an expected loss of $2.70 for every $100 wagered, over the long run.

Fewer pages, real numbers
We publish slowly. Each guide is paired with a tool or a game that proves its numbers, and every figure comes from the game's rules, not from a marketing sheet.
Everything here is free to use and plays with pretend chips. Some pages end with a clearly labelled sponsored card; it never appears inside a tool, and it never changes the maths. How we work
