Clear as many pieces from the board as possible.
Click on groups of colored pieces to remove them from the board. When you remove a group from the board, it will resize, unveiling additional groups of colors. Strategically remove specific colored groups until you are able to clear the board of every piece.
If a point is reached where the game board has no more possible groups, the game will be ended, with your final score being the number of remaining pieces on the board.
