Just say 'rock', 'paper', or 'scissors' and see if you beat your opponent! Also, this is randomized, not rigged. If you keep loosing and/or keep tying, you just have bad luck.
This is 100% randomized. So don't go in the comments saying "This game is rigged. 0/10. Would not recommend" or anything else like that. And speaking of random, this is my first game with random results. This text is random, just like your opponent's choices.
