How Online Craps Works
Craps is played with two dice, and every round starts with a come-out roll. Most players begin with the Pass Line, the simplest bet on the table:
- Come-out roll of 7 or 11: the Pass Line wins straight away.
- Come-out roll of 2, 3 or 12: this is “craps”, and the Pass Line loses.
- Any other number (4, 5, 6, 8, 9 or 10): that number becomes the point.
- After the point is set: the Pass Line wins if the point is rolled again before a 7, and loses if a 7 comes first (“seven-out”).
The Don’t Pass bet works the other way round. It wins on a come-out 2 or 3, ties on 12, and loses on 7 or 11. Once a point is set, it wins if a 7 is rolled before the point.
Online, you place chips by clicking the betting areas on a digital layout. In RNG craps, a random number generator decides each roll. In live dealer craps, real dice are thrown in a studio and streamed to your screen.
Dice Probabilities
With two dice there are 36 possible combinations. Seven is the most common total, with six combinations, while 2 and 12 have only one combination each. These odds explain why 7 matters so much in craps and why bets on single rolls of rare totals pay more but cost more over time.
Craps Bets, Payouts and House Edge
| Bet | Pays | House edge |
| Pass Line / Come | 1:1 | 1.41% |
| Don’t Pass / Don’t Come | 1:1 (12 is a tie on the come-out) | 1.36% |
| Odds behind Pass or Come | 2:1 on 4/10, 3:2 on 5/9, 6:5 on 6/8 | 0% |
| Place 6 or 8 | 7:6 | 1.52% |
| Place 5 or 9 | 7:5 | 4.00% |
| Place 4 or 10 | 9:5 | 6.67% |
| Field | 1:1, 2:1 on 2 and 12 | 5.56% (2.78% if 12 pays 3:1) |
| Hard 6 or 8 | 9:1 | 9.09% |
| Hard 4 or 10 | 7:1 | 11.11% |
| Any Craps | 7:1 | 11.11% |
| Any Seven | 4:1 | 16.67% |
These figures are for standard payouts. Online tables can use different payouts or limit how much you can bet on Odds, so check the game’s help screen before you play.
Why the Odds Bet Matters
Once a point is set, you can add an Odds bet behind your Pass Line or Come bet. It pays at true odds, so it has no house edge. Adding Odds lowers the overall house edge on your combined bet, which is why experienced players use it. Its size is limited by the table rules.

Where to Play Craps in Ontario
Craps is less common online than blackjack or roulette, and some Ontario casinos do not offer it at all. Among the brands we review, Spin Casino, Casumo and Betway list craps in their Ontario game lobbies. Game lobbies change, so check the table games or live casino section of the casino’s Ontario site before you register.
Only play at casinos registered with the AGCO and operating under iGaming Ontario. Licensed sites must use tested games and offer responsible gambling tools such as deposit limits and time reminders.
Craps Tips for Beginners
- Start with the Pass Line or Don’t Pass. They have some of the lowest house edges in the casino.
- Add Odds when you can. Odds bets have no house edge.
- Prefer Place 6 and 8 over Place 4 and 10 if you want place bets.
- Treat proposition bets as entertainment. Any Seven, Any Craps and the Hardways carry much higher house edges.
- Remember that every roll is independent. No pattern or system changes the odds of the next roll.
Craps vs Sic Bo
Both are dice games, but they work differently. Craps uses two dice and rounds that can last several rolls, while sic bo uses three dice and settles every bet on a single roll. If you enjoy dice games with low-edge bets, the Pass Line in craps and the Big and Small bets in sic bo are the places to start.

Craps rounds can move quickly once you place several bets at once. Set a deposit limit and a session budget before you play, and take regular breaks.
