You control everything with the mouse. The game presents you with a grid of face-down tiles, and you click one to reveal a picture, then another to find its match. If they match, the pair stays face-up. If not, both tiles flip back over, and you have to remember their positions for your next turn. The main objective is to clear the entire board by finding every matching pair. The pace is quiet and thoughtful, though the difficulty can ramp up as the grid size increases and the number of images grows. It feels like a simple, focused test of memory.
