Totally insane. David C. Lovelace’s RPS-15 takes Rock Paper Scissors into the dank, freaky halls of every asylum by adding Fire, Snake, Human, Tree, Wolf, Sponge, Air, Water, Dragon, Devil, Lightning, and Gun. That’s over a trillion permutations.

If your Roshambo (Rock Paper Scissors) contests require more complexity than three gestures, take my advice and start with RPS-7, or back off even further to Sam Kass’s five gesture varient, Rock Paper Scissors Spock Lizard.

Wikipedia has a nice entry for Rock Paper Scissors, covering international variants and strategies, history, and cheating.

Serious Rock Paper Scissors combatants will want to consider looking into the Official Rock Paper Scissors Strategy Guide, by Douglas and Graham Walker.
