Just in case you didn’t have enough geeky devices to help you with gaming strategies, here’s a glove that allows you to play rock-paper-scissors against a computerized opponent.

Also called ro-sham-bo (the phonetic French expression of “rock-paper-scissors”), there are some people who take this WAY too seriously.  There are actually roshambo tournaments, and it even has been expanded to include five symbols (as seen in the 2008 “The Lizard-Spock Expansion” episode of The Big Bang Theory).

One can apply game theory to figure out the optimal winning strategy to rock-paper-scissors.  In order to prevent your opponent from taking advantage of any patterns that you may express, you should use some kind of randomizing device to determine your throw.  Doing this results (in the long run) of winning 1/3 of the time, losing 1/3 of the time, and tying 1/3 of the time – basically, you shouldn’t lose.
