The sport originated in the late 1940s in St. Louis, Missouri so that if 18 players weren't available to play a regular baseball game, or a full sized field wasn't available, they could play an alternate game much like baseball but for fewer players.
[1] Indian Ball is played in any size area from a regular baseball field to a side yard or street.
If the ball is put in play and hits or is touched by the pitcher it is an automatic out.
If in any case an infielder plays a ball in the outfield or an outfielder plays a ball in the infield it is an automatic double (two points).
A ball that is caught by a player in all locations (fair, foul or deadzone) without hitting the ground results in an out.
