Janken Pon! which is Japanese for Rock, Paper, Scissors.
Pretty simple game. Has two different modes: Player vs. Computer and Player vs. Player.
In Player vs. Player, the computer chooses your sign for you and you cant choose another sign for at least five seconds. This prevents players from cheating by quickly tapping the screen and drawing a new sign.
In Player vs. Computer, you can choose from rock, paper, and scissors. The computer chooses a sign at random.
The computer has a 33/100 chance for each sign, except for Tiger Claw. Which has a 1/100 chance of being picked. And nothing beats Tiger Claw!!
