MagicBalls is a single-player game in which the objective is to score points by creating rows of three or more balls of the same color. You create a row by swapping two balls. Each time a row of three occurs, those balls are removed and the remaining balls drop down, creating new combinations. You can set the board size up to 9x9 squares. A hint feature shows possible moves, or you can search without the computer's help. Scoring is automatic, and there's a high score honor roll with funny icons. Other options let you choose 3D or flat images -- or let a single light source emanate from the mouse cursor to illuminate the balls and create shadows.
