A simple yet challenging game which exercises your brains "computational perception" circuitry: your ability to "notice" non-obvious relationships between objects in your surroundings.
To play: Find matches of three tiles where each trait (shape, shading, number, color) is all the same or all different. Look at the examples in "Instructions" to quickly grasp the concept.
Each game lasts about 90 seconds, or work with "training" mode to hone the basics.
"Mind bender" mode adds a very challenging twist to the game by turning the rules inside-out!
