Wiffle ball is similar to baseball.
There are two sides of 3-5 players.
The fielding side selects a pitcher who tries to get the batter out.
There are two outs per inning and five innings per game.
The batter can get out in several ways.
He can strike out, ground out, or fly out.
There are three strikes to strike out and six balls to walk.
A strike is either a ball that is swung at and not hit into play or a ball that hits the strike zone.
If the ball hits the strike zone and the batter does not swing, it is considered a "called strike."
Additionally, any of the first three pitches in an at-bat are a called strike, the batter is called out.
This is called the "one and done" rule.
A ground out is a ball that is grounded and fielded cleanly by any fielder inside the double line.
A fly ball is a ball that is caught before it touches the ground.
If a ball is hit past the double line on the ground it is a single.
All runners including the hitter advance one base.
If a ball is hit over the double line on the fly, it is a double.
All runners including the hitter advance two bases.
If a ball is hit over the double line and bounces past the home run line, it is a triple.
All runners including the hitter advance three bases.
If a ball is hit over the home run line on the fly, it is a home run.
All runners including the hitter score.
