An epic game played on a single wall that probably originated somewhere in Encinitas, California. Several people start off at first, hitting the red ball (about the size of a tether ball) against the wall. The server chooses order. The ball must bounce (only once) before hitting the wall, then the next person catches or hits it after no or one bounce(s). The server can call certain things, such as Sudden Death (only hits). One is out if they fail to hit the ball or follow any of the other rules on their turn. Last standing wins.
In some forms of the game, players are allowed to rainbow (go under the ball) for their turn.
A version of a game called wallball, which is the same as Elimination except its only two people.
Elimination is the best game invented that you can play on a wall.
