Ultamite Ninja
A circle game that involves people doing only one move in an attempt to hit a persons wrist or hand to get them out. This game is widely popular among high school and college youth groups on the West Coast. Although not well known nationally or universally like tag or can be found on YouTube, its still extremely fun if taught by an experienced player.
Instead of getting into a fistfight, the Green West Valley Cross Country team challenged their archrival team Blue East Mountain Cross Country team to a game of Ultamite Ninja. Blue East wins but challenges Green West to Fast Ninja.
