How in the world does a bot get a 76:1 record in a game of chance?
It's more like poker in that it's a game of statistical strategy. You can throw more than just rock, paper, and scissors, there are 100 dynamite and unlimited water balloons to throw. Timing when you do this will help you win or lose a match.
One of the things you can do, also, is know who your opponent is and adjust your strategy appropriately. If they happen to follow a pattern, you can adjust to counteract their pattern.
