If you can imagine a game of baseball or softball with no bat, and substituting a soccer ball or similar for the baseball, then you get the idea of what this game is about.
Two teams, one fielding, one kicking.
Everyone gets a kick! The pitcher rolls the ball gently to the kicker, who after kicking has to run to first base.
The other rules can vary to suit the ages of those playing, but follow baseball and softball closely.
