Collapse the blocks by clicking groups of horizontally or vertically connected same-color blocks. On each collapse you will obtain a score. The bigger the group you collapse, the higher a score you will get. The status at the bottom will show you the projected score for any selected group. You can apply logic to create bigger groups. Your progress will be saved. So feel free to play it again and again to obtain a higher score. Don't let the board fill from blocks to keep game going.
