Why Two Ones Are Called Snake Eyes
“Snake eyes” is the familiar name for rolling a one on each of the two dice. The name comes from their matching appearance: each die shows a single pip, like a pair of small eyes. In craps, though, the roll’s effect depends on when it happens—not just on the total.
The Pass-Line Bet Has a Risky First Roll
A pass-line bet is placed before the shooter’s first roll, called the come-out roll. A 7 or 11 wins immediately. A 2, 3, or 12 is “craps,” and the pass-line bet loses. The other totals—4, 5, 6, 8, 9, or 10—set a point that the shooter must roll again before a 7 to win.
That makes snake eyes an especially costly opening result for a pass-line bettor: the dice show 2, so the wager is lost before a point is established. The paired ones are memorable, but it is the total and the bet’s rules that decide the outcome.
The Same Roll Can Mean Something Different Later
Once a point has been set, a 2 does not by itself end the pass-line bet. The shooter keeps rolling; the bet wins if the point appears again before a 7. So snake eyes is not an automatic loss on every turn—it is a loss when it comes up on the come-out roll.
That timing is a small but important part of craps: a dramatic-looking pair of dice can be decisive at the start of a round and merely another roll after the game’s point has been established.
