Holy CRAP! You can’t stop geeks from ruining the simplest of games, like Rock Paper Scissors, can you? (In Singapore, it’s called Scissors Paper Stone, but that’s just semantics, I guess.) First, you have the “World RPS Society’s” gambits for competitive RPS, otherwise known as three-step strategies for winning the game.

And, if that’s not enough for you, you can try RPS-15, which is the game with 15 hand signs, giving you 1.3 trillion permutations, or RPS-25, for 15.5 octillion permutations.
