In this puzzle game, you will be given a grid full of blocks, and you will need to eliminate blocks by filling up rows, columns, or 3×3 grids. To complete each level, you will need to find and remove the unique solution. If you can’t figure out the answer on your own, you can try using the hint button.

There are two ways to complete each level. You can fill up rows, columns, or 3×3 grids by removing blocks, or you can use the hint button.

If you ever get stuck on a level, you can use the skip button to skip to the next level.

There are five game modes: Classic, Endless, Story, Timed, and Ranking.
