Simply put, it's slowpitch softball with one pitch per at bat. A ball is a walk. A strike is an out, whether it's a called strike or a foul ball. And, a hit is a hit. The one exception occurs when the batter hits the ball back to the pitching screen. This results in a dead ball. A batter hitting the screen two times in a single at bat results in an out.
And that's it. No watching batters work the count or wait for a great pitch. The games move fast with pressure on the pitcher to throw strikes and on the batter to put the ball in play.
