You need to catch the colored ball with the suitable side of the square.
If for example a blue ball falls, you need to turn the square towards the ball with the blue side. Otherwise, you will lose.
The goal of the game is to match the color of the falling balls by rotating the square at the bottom.
It's easy at the beginning but it gets harder when the speed increase.
