Butts Up

Butts Up or Wall Ball is a North American elementary school children's playground game originating in the 1950s or earlier.. It is slightly similar to the game Screen Ball, and began in the 1940s or 1950s as a penalty phase of various city street games. Butts Up is played with a ball (such as a tennis ball, handball, or racquetball) on a paved surface against a wall, with a variable number of participants—usually more than three and often likely to exceed ten. Butts Up tends to be played during recess, before or after school. . Popular in New England is another frequent variation of wall ball that usually differs a lot from the more widely known 'Butts Up'.

Players determine the variations of the game prior to start of play. Some of the rules of the game very loosely resemble the rules of baseball and racquetball.
