This is an indoor baseball game best played in a small auditorium (ours seats about 180 max.) I recommend a foam bat and a FOAM ball so nothing gets damaged.
Start the game with multiple teams (3 or more is best) of any number of players per team. You will need a scorekeeper with a whiteboard and marker, or just paper and pencil if you’re boring 😉 There is one batter standing on or near the stage, facing the auditorium. There is one pitcher, put your mound wherever it is easy to pitch from. Every other player is a fielder, standing wherever they choose.
Teams take turns batting homerun derby style. Each player gets three hits on the ball (hits, not pitches or strikes). Pitchers may rotate as you see fit, usually when the batters do. Team with the most points wins.
Scoring points are assigned for the following reasons:
Retrieve the ball after hit: 1 point
Catch the ball out of the air: 2 points
Your hit caught out of the air: -1 point
Hit an easy object: 1 point (For our game, these were two huge banners hanging from the balcony, the size of bed sheets.)
Hit an impossible object: 10 points (four very tiny windows on either side of the banners were open. No balls went through in 45 mins!)
Break the projector: -50 points and -$1500
Most points will be won by retrieving balls, so it becomes a frenzy for students trying to push each other out of the way and dive to the ball first. Teammates can retrieve hits from their own team’s batter. The pitcher may retrieve or catch hits. If you have a way to mark teams for the scorekeeper (i.e. team bandannas) it’s a good thing.
