Craps is one of the most exciting and social casino games ever created, centered around the roll of two dice. Players bet on the outcome of dice rolls at a specially designed table featuring dozens of betting options. The game dates back to the early 19th century and has evolved into the high-energy spectacle found in every major casino worldwide. The odds bet in craps is the only bet in any casino game with zero house edge, paying true mathematical odds.
A craps game flows through two main phases:

The Pass Line is the most fundamental bet in craps. On the come-out roll, you win instantly if the shooter rolls a 7 or 11, and lose on 2, 3, or 12. Any other number sets the Point. Once the Point is established, you win if that number is rolled again before a 7 appears. The Pass Line has a house edge of just 1.41%, making it one of the best bets in any casino.
The best bet in craps is the Odds bet, placed behind your Pass Line or Come bet after a Point is established. It pays at true mathematical odds with absolutely zero house edge — the only such bet in any casino game. Points of 4 or 10 pay 2:1, points of 5 or 9 pay 3:2, and points of 6 or 8 pay 6:5.
Odds bets are additional wagers you can place behind your Pass Line or Come bet once a Point is established. They pay true odds with no house advantage: 2:1 for 4/10, 3:2 for 5/9, and 6:5 for 6/8. Casinos typically limit odds bets to 3x-5x your original bet. Combining a Pass Line bet with maximum odds is the mathematically optimal strategy in craps.
