Color Tiles Puzzle

|| HOW TO PLAY ||
The game rules are very simple - you just tap on a square and it changes colour along with the other squares adjacent to it. Color switching normally occurs from RED to GREEN, from GREEN to BLUE and from BLUE to RED (Yet there are some exceptions on higher difficulty levels). Your objective will show up every time you start a new game and will tell you which colours you should make all the tiles on the screen.
