In craps, Snake Eyes is the outcome when both dice show a one, making the total value of the roll two. This roll is considered very unlucky, as it results in an immediate loss for the player on a come-out roll in most betting situations, except in specific side bets where it may have a different effect.
Snake Eyes Example
For example, if a player places a pass line bet and rolls Snake Eyes on the come-out roll, they immediately lose the bet because the total of two is not a winning number.
