is the latest effort from Puzzle Lab that plays unlike any other matching games released, but still one nonetheless.
Basically the player has to place three rings of the same color but different sizes together to make them disappear. The game ends if you allow a ring to touch the insignia. An issue I had with the game was that the ring placement system is a bit awkward. Players have to be mindful of the order in which they click on the rings as these could be placed in front as well as the back of the queue.
