If you can't input a play, wait until Sheldon is done asking you what you are going to input. If that doesn't work, then my program just sucks. When you win/lose press the green flag to go again. Raj: I’ll tell you what, how about we go rock-paper-scissors? Sheldon: Ooh, I don’t think so. No, anecdotal evidence suggests that in the game of rock-paper-scissors, players familiar with each other will tie 75 to 80% of the time due to the limited number of outcomes. I suggest rock-paper-scissors- lizard-Spock. Raj: What? Sheldon: It’s very simple. Look, scissors cuts paper. Paper covers rock. Rock crushes lizard. Lizard poisons Spock. Spock smashes scissors. Scissors decapitates lizard. Lizard eats paper. Paper disproves Spock. Spock vaporizes rock. And as it always has, rock crushes scissors.
