Clear the GEMS (Full) for Windows 8 is a simple-ruled and challenging puzzle game. For a free user, you can play the first 25 levels without any limitation. Slide a gem to the left or right. If there is an adjacent gem on the sliding direction, the two gems will exchange their positions. Moving three or more gems with the same color together in a row or column will eliminate them all. A level is completed if you eliminate all gems. You have limited number of "slides". If you run out of slides, you get to start a level over. Some levels may be easier to pass if you can benefit from a multi-touch screen. Without that you may be improbable to pass some other levels.
