You roll four dice, pair them up, and advance markers on a stop-sign-shaped board. The numbers 2 and 12 have very short tracks, while 7 is incredibly long. The choice is always simple: stop and lock in your progress, or roll again and risk losing everything from this turn.
It is the purest form of push-your-luck. The plastic cones are basic, and the board looks bare. However, watching your friend bust on a greedy roll is worth every second.
