The objective in this tile matching game is to collect all of the sparkling gems in a level before the time runs out on the ticking pocket watch. The number needed for the level is displayed above the main grid. Swap one stone at a time by choosing a pair, which trade places with a click, slowly eliminating all those which contain gemstones. The entire board can be shuffled twice and hints can be purchased for the cost of points.

There are also timed mini-games sprinkled throughout the game which provide more opportunities to earn gold stars.
