Rock-paper-scissors is a hand game played by two people. The game is also known as roshambo, or by other orderings of the three items (with "stone" sometimes substituting for "rock").
The game is often used as a choosing method in a way similar to coin flipping, drawing straws, or throwing dice. Unlike truly random selection methods, however, rock-paper-scissors can be played with a degree of skill by recognizing and exploiting non-random behavior in opponents.
