Press space to generate a new puzzle. Each tile has a number. Click on a tile, and that tile, along with every tile surrounding it (including corners) will be lowered by one. If a number goes below zero, you lose, and you need to generate a new puzzle. Get all of the tiles to 0 to win! (Note: Every generated puzzle is possible) PLEASE do not post fake codes in the comments. Thanks to st19_galla for curating Zero!
X.X: Added a "9" Tile, and another tile change. Yes, it is still possible...
