Sort the cards into the correct pile to gain points. Sorting them into the wrong pile will result in point loss. Can you beat the High Score? This game actually improves the deeper thinking of your brain because it forces you to always be thinking. Much of the time, we figure out how to do something and our brains create a new neuron path, which then forms habit. This means you aren't having to think nearly as much as you did the first time you did the thing. This game forces you to be constantly thinking because you can't form habits as the color is completely random every time.
I got the idea from a minigame in Mario Party 8. This game is MOBILE FRIENDLY :)
