Duo (Craps term)

In the game of craps, the term “duo” refers to a bet on the numbers 11 and 12. This bet is made by placing chips on the line between the 11 and 12 on the craps table. The duo bet pays out at 17-1 odds if either the 11 or 12 is rolled on the come-out roll, or if either of these numbers is rolled as a point. This bet is considered to be a one-roll bet, because it will be resolved on the next roll of the dice, regardless of whether or not a point has been established.
