Purple Rain! Number SAME GAME

"Purple Rain!" is a slow-paced puzzle game with no time limit and no action.

◆How to play
Tap the tiles with numbers on them. The number will decrease or increase.
If there is a tile with the same number on the left, right, top and bottom, the number will increase by one.
If there are no tiles with the same number next to each other, the number will decrease.
Combine the tiles well so that all tiles are purple (5). That is "Purple Rain!"
