The main goal of the player is to clear the field from the balls, clicking on the balls of the same color. The field is 13 balls wide and 17 balls long. When the entire column is cleared, the nearby columns shift to the right. If the player manages to clear the entire field, he or she receives a bonus at the end of the game. You can adjust the difficulty level of the game by choosing the number of ball colors that you are playing with.
