This is the best application for understanding the process of "photographic memory." I hope more people will use this application and discover new ways to use their brains.

"Concentration!" puts its emphasis on understanding the process of "photographic memory." I think most people try to remember just the position of cards with the same pictures, as they are flipped over in order the first time they play the game. This is fine at first. However, if you consciously try to remember the cards as an image, "photographic memory," as you continue to play the game you will start to understand what I mean by "a new way to use your brain." I want all of you to feel the way I do now!
