The purpose of this cool flash game is to exercise your brain and enhance your mental response-time. Just like the classic game but with some cool new features. You can use YOUR MOUSE or the ARROW KEYS to play. (Arrow keys are best if you want a good response time). A cool challenge is to try to get to 10 level with a response time under 200ms. Also try playing without looking and call it "Blind Samurai Saimon Style". Have fun!
