Assemble the blocks by clicking on groups of horizontally or vertically connected blocks of the same color. With each collapse you will get a grade. The larger the group in which you collapse, the higher your score will be. The status at the bottom will show you the projected result for any selected group. You can apply logic to create larger groups. Your progress will be saved. So feel free to play it over and over again to get a bigger score. Do not allow the board to fill out of the blocks to keep the game going.
