What does this roulette or craps bet cost?
Pick the wheel or the craps bet in front of you, your bet and how fast the game runs. See the house edge worked out from the payouts, your chance to win, what an hour is expected to cost and how far an hour can swing.
At roulette the wheel sets the price, not the bet: every bet costs 2.70% on a single-zero wheel, 5.26% on a double-zero wheel and 7.69% on a triple-zero wheel. The one exception is the top line (0, 00, 1, 2, 3) on a double-zero wheel, at 7.89%. At craps the pass line costs 1.41% and don't pass 1.36%, and the odds behind them cost nothing, so a pass bet with 3x, 4x, 5x odds costs 0.37% of all the money you put down. The one-roll bets in the middle of the table cost 11% to 17%. At $10 a spin and 38 spins an hour on a double-zero wheel, the expected loss is about $20 an hour.
Choose the game and the bet
Every figure updates as you choose. The wheel type is on the wheel and the layout: look for a 00 (and on some wheels a third zero).
On this wheel every bet costs the same 5.26%; only the top line costs more. An hour of this is $20 down on average, but most hours land anywhere from about $82 down to $42 up.
Every house edge here is worked out from the payouts by counting the pockets on the wheel or the 36 rolls of two dice, and checked against Wizard of Odds on roulette and on craps. The link you copy keeps your choices after the # in the address, which isn't sent to our server.
How the math works
Table games don't hide their math: the payouts and the wheel or the dice are all you need.
- Roulette. A bet that covers some of the wheel's pockets and pays a fixed amount returns, for every full turn of the wheel's pockets, less than you put in. A straight-up bet on a double-zero wheel wins once in 38 spins and pays 35 to 1, so 38 spins at $1 return $36: an edge of 2 in 38, or 5.26%. Every bet on the layout is priced the same way, so on one wheel the edge is the same on red as on a single number. The top line covers five pockets and pays 6 to 1, where a fair price would be 6.6 to 1, which is why it costs 7.89%.
- Craps. The tool counts all 36 rolls of two dice for each bet. A bet that stays up, such as a place bet or the point on a pass bet, is followed roll by roll until it wins or loses; rolls that don't decide it are skipped. Pass wins 244 of every 495 decisions and loses 251, an edge of 7 in 495, or 1.41%.
- Per bet or per roll. The main figure is per bet: what you lose on average for each dollar you put down, from the time you make the bet until it's settled. Craps players also quote it per roll, because a place bet stays up for several rolls: place 6 costs 1.52% per bet but only 0.46% per roll. Don't pass costs 1.36% per bet counting the 12 as a push, or 1.40% if the pushes are left out. The tool shows each.
- Odds. The odds bet pays true odds, so it has no edge. It doesn't change what the line bet costs, but it adds money to the table, so the cost as a share of everything you bet falls: pass with 3x, 4x, 5x odds costs 0.37%. Your swings get bigger by the same token.
- Per hour. Expected loss per hour = bet × bets per hour × house edge. The typical swing is one standard deviation of an hour's result. About two hours in three land within one swing either side of the expected loss.
The figures assume the usual US payouts listed with each bet. Some tables pay differently (Wizard of Odds lists 2 and 12 bets paying anywhere from 29 to 33), and a different payout gives a different edge. Ask the dealer when it isn't printed on the layout. What each cruise line publishes about its tables is in table games on cruise ships. Why the edge comes from the rules, and how comps rate table play: the math behind casino games. For blackjack, what does this blackjack table cost? does the same job.
Play responsibly
Every bet here except the craps odds bet has a house edge, and the odds bet only comes with a bet that does. The hourly figure is a long-run average. In one session you can lose much more, and a win doesn't mean a system works. Set a budget for the cruise before you board, and don't raise your bets to win back losses.
