Press space to start the game. Certain tiles will turn blue that you have to remember. Then after they turn back white, try to click the tiles that turned blue. If you get a tile right, it will turn blue. If you get it wrong, it will turn red. Once you have clicked the same amount of tiles it showed, it will show you a new pattern. See how long you can go without getting 10 tiles wrong!
I was inspired by a game in the Apple app Peak Brain Training. Otherwise, it's all mine. And I know, there are some glitches.
