Click tiles to rotate them. Rotate as few tiles as possible. You can't click too much. You will still win as long as all tiles are rotated correctly in the end.
Update: Added edges. Thanks, @agentaj8 and @Fly1ng_Bread! - Thanks for all the likes and faves! I am flattered. - Please stop saying the game is hard and I should make it easier. It is really easy enough and more than that would ruin the fun! #pattern #patterns #puzzle
