For Grades 3 - 6. Wiffle ball is a competitive, clean league that includes playoffs, trophies and statistics. It's like baseball but with a hollow plastic bat and plastic balls made with unique (and often oblong) holes. For most wiffle ball game variations, you have the exact same goals as in baseball. Pitch the ball, hit the ball, move runners forward, and get the batter out. If you've got young baseball fans in the family, this is a great game to share with them.
Why not just play baseball or softball you may be asking? Those can be fun games for kids too, but there's a lot of cool things about wiffle ball that place it in a class all its own.
