Press space to run generation! If scissors touch rock, they become rock. If paper touch scissors, they become scissors. If rock touch paper, they become paper. Each figure moves towards the closest one that it can infect. It seems to me that in any case you just have to wait, and someone will win. You can change the settings of the simulation in the top part. Also, you can drag them! (I don't think the "AI" of these figures is very good)
