This is a Rock, Paper and Scissors game. You have 15 seconds and have to guess who the winner is every time that a game is played. If you guess in less than 0.5 second, you will get a “fast” bonus and 3 points. From 0.5 to 1, you will get 1 point and for more than 1 second, you will get 1 point, but also lose 2 seconds (because of being slow). For draw, you will get 2 points and for wrong guesses, you will lose 3 points. The goal is to score higher at the end and the game will rate you according to your score.
