Circulate

Circulate is another variation in the matching tiles sub-genre of casual games. This time, the player has to rotate a circle at the center of the screen with the mouse. The inside surface of the circle is constructed as a maze, and the balls residing in its nooks and crannies fall as if obeying the laws of gravity.

The main objective of most levels is to link spheres of the same color in order to make them disappear. Some levels require moving the balls to a container. Other levels require that spheres destroy each other (fire balls destroy ice balls, and vice versa).
