Roshambo is not only a game of “sack tapping”, it is also a hand game of probability and skill, a game of selection between ROCK-PAPER-SCISSORS. In our case, music selection. We like to promote it.

Rock-paper-scissors is a hand game played by two or more people. The game is known by many names, including other orderings of the three items in the name (with “stone” sometimes substituted by speakers of British English)

The game is often used as a selection method in a way similar to coin flipping, drawing straws, or throwing dice. However, unlike truly random selection methods, rock-paper-scissors can be played with a degree of skill, especially if the game extends over many sessions with the same players; it is often possible to recognize and exploit the non-random behavior of an opponent
