Click or tap to place each next block on the board, either all on black squares or all on white squares. When the blocks get larger and more difficult, you will need to rely the Park ability to skip blocks that you can't place right away, or to save them for future use. At the start, each move is worth 1 point. This increases by 1 each time you clear the board to all black or all white. This is the way to the highest scores!
