TapToClean is a puzzle game in which you need to clean a square board.

The square board is from 5x5 to 8x8, and each cell could be green or white.

When you touch on a cell, the color of that cell and all of its adjacent will be converted:
- White cells will become green.
- Green cells will become white.

Repeat touching until all cells are white.

If you feel it is too hard to complete this level, press "Next level" to go to the next level.

WARNING: You will lose if you run out of time.
