Craps — rules

How Craps plays in OmertaEra, the free Prohibition-era mafia MMO. The same rules are shown where the game is played, and every outcome is provably fair.

Two dice and one shooter for the whole room. Every round is one roll: bets close 30 seconds after a round opens, and a roll comes every 36 seconds. The table keeps the point from roll to roll. With the point off (the come-out), a 4, 5, 6, 8, 9 or 10 becomes the point; it stays on until that number is rolled again or a 7 comes. A bet stays on the table, round after round, until it is decided — you can add more on a later round.

Pass line
Come-out 7 or 11 wins, 2, 3 or 12 loses; any other number is the point, which must come again before a 7. Pays 1 to 1. Only on the come-out. returns 98.59%, house edge 1.41%.
Don't pass
Come-out 2 or 3 wins, 12 is a push (bar 12), 7 or 11 loses; then a 7 before the point wins. Pays 1 to 1. Only on the come-out. returns 98.64%, house edge 1.36%.
Field
One roll. 2 or 12 pays 2 to 1; 3, 4, 9, 10 or 11 pays 1 to 1; 5, 6, 7 or 8 loses. returns 94.44%, house edge 5.56%.
Place 6 / 8
The number before a 7, paid 7 to 6, so it goes down in $6s. Working on every roll, come-out included, until decided. returns 98.48%, house edge 1.52%.
The dice
Out of 36: 4: 3 ways against 6 · 5: 4 ways against 6 · 6: 5 ways against 6 · 8: 5 ways against 6 · 9: 4 ways against 6 · 10: 3 ways against 6.
  • One layout per player per roll, and the table limit covers that layout. What was already riding from earlier rolls does not count against it.
  • A craps room nobody has rolled in for 10 minutes, with nothing riding, gets a new shooter coming out.
  • Every roll a bet rode is logged with that round’s revealed seed, so the whole run replays on the fairness page.
