Triad will train your brain!
The task is to find three matching tiles out of the 16 tiles on the screen. A tile has four attributes: number, color, shape and fill. Each attribute has one of three values. For example, the top-left tile in the screenshot below shows one maroon figure-eight that is not filled out. You found a triad if you found (and tapped) three tiles where each one of the attributes is either completely different, or they are all the same. The highlighted triad in the screenshot has all different numbers, all different colors, only one shape (the figure-eight), and all different fills.
The quicker you find triads, the more points you get. If you think the game is getting too easy, you can switch to 12-tile mode, where its much harder to find a triad, since there arent so many of them on the screen. In return, you get more points.
