Four square

In most sports, there are two teams or players, but there is an interesting game that can have four competitors.
It’s not very popular in the world, but teenagers in many countries love four square.
This game has simple rules and is easy to play. Four players stand in front of each other on four squares.
The squares are all next to each other. The players hit the ball with their hands.
The players can’t hit the ball with their feet. The ball hits the other player’s square.
Then he or she hits the ball into another player’s square. The players can’t hit the ball two times.
When do you lose? When you can’t hit the ball in your square or when your ball goes out of all the other squares.
