Nope! WHy? You can barely see any difference.

It's either a very short game or too hard for me. I would suggest it to start easier and have an even background.
To add something new to this type of game: How about the possibility to move/drag tiles? So we can check if what we see isn't an illusion due to the placement of the tile.

Interesting game, but depends far too much on the quality and contrast of ones monitor.

Good challenge

I'm afraid I don't understand- how do you tell which is a different color? They are all the same color and shade in my eyes. No matter how much I kept trying, in the end it became a guessing game.

Some further information would greatly be appreciated. Thank you.
