From C64CG website, "Play this amazingly realistic simulation of the playground game Rock, Paper, Scissors - all on your own with no need to have friends or anything because you're up against the computer - it's absolutely brilliant!

Plug a joystick into port two; when playing select rock hold the stick left, leave it centred for paper and hold right for scissors. When you have selected a move,press fire and the computer will make its selection."
