Place the hats in a square with about 5 m between them.
Two players are the catchers, the rest move inside the square.
The 2 scapegoats can tap the other players with the ball. The catchers are not allowed to walk with the ball.
By throwing over the ball the taggers can tap the other players.
If you are tapped or outside the square you are finished and may leave the square.
Variation:
When players are out, they belong to the taggers instead of being out of the box.
