I390

In this app you can see red and blue tiles randomly placed on a square board. Your task is to change them all to blue.
Sounds easy, doesn't it? Yes it does.
However there is a rule of flipping the tiles: if you click on a tile, then the four neighbour of it will be rotated.
Your goal is to make the whole board blue (which is a much more harmonic and calm color than red ;) ).

Don't be afraid of this challenge! You can change the size of the board from 1 to 10, and I can assure you that size 1 is really easy (actually easier than you think, but try it yourself).

And the most important part, is what you will see when you make all the tiles blue. Of course I won't write a spoiler about it, but the end of this game has a deep spiritual content (if you think I'm joking, solve the game, think about the ending, and if you are intelligent enough you will understand what I'm talking about).

HAVE FUN!
