This is a game based on the game “four-square” played all over the world. If the ball goes to your square, you have to hit it so it first bounces in your square and then in someone else’s. If you make a mistake, you are out, everyone who was in a lower square moves up, and a new person enters the game in the lowest square (on the bottom-left). The highest square (top-left) is the king square, and if you make a mistake here, you only move to the lowest square, instead of going out.
You are the blue player. You earn points for staying in and playing fast shots. You earn double points when you are in the highest two squares. When you go out, your game ends.
