Downball (occasionally known as wallball) is a multiplayer game where players take turns hitting a tennis ball with their hands against a wall until a player misses a shot and is eliminated. The last player left is declared the winner and the next round begins. It is usually played by schoolchildren. Downball walls were built in school yards. The game has been popular in Australian schools, especially in Melbourne and elsewhere around Victoria. A full player (aka a player "in full life") who catches a shark shot stays in play and puts the person who played the shark shot "onto the wall".
