This is a fast moving version of kickball for large groups. This version enables everyone to get up to bat several times in a short period of time.
The concept is the same as kickball except that you have three pitchers pitching to three kickers simultaneously. Once you are on base you do not have to advance a base unless you want. Therefore you can have several people on one base at a time. Instead of there being three outs we make it nine outs before the next teams gets up to bat.
The defensive team can stand anywhere around the playing field. Try it and modify it to suit the needs of your group.
