This is “our” version of indoor-baseball.
You have to have at least 8 people to play a decent game. You have 4 players on each team. You set up 3 chairs for the bases. Home plate is chalk drawn on the cement. If you have carpet or tile, you can use paper) In our church, the pulpit is behind home plate, so we draw an umpire, and if the ball hits it, it was a good throw and counts as a strike.
You play like regular baseball, only you have to sit on the bases (chairs)
