Rock paper scissors rules
Rock beats scissors, scissors beats paper and paper beats rock; the same choice on both sides is a draw. Pick your move and the computer reveals its own at the same moment. Play a single best-of-three, a best-of-five, or keep going in endless mode.
On easy you win most rounds, medium is roughly an even game, and hard wins more often than it loses. Against people, remember that they are rarely truly random: most repeat a winning move and switch after a loss.
