Pick and drop blocks’ stacks inside the board to make a complete horizontal or vertical row of blocks. The more rows you make in single drop, more score you will get. There is no power up, no time-limits but the space limit. You will have 100 blocks’ board, and you must have to keep room for fitting the upcoming blocks, otherwise you will lose it. At a time you will have 3 stacks, and another will come, once you fit the current three.
