Here´s how to play:

1. Position your cube along the lower left or right edge of the board, then left-click to release it.

2. The cube will slide in a straight line until it hits another cube or the end of the board.

3. When three or more cubes of the same color touch each other, they disappear as a group. Eliminate the required number of cubes to reach the next level.

Note: This game works best with Internet Explorer 5.0 or later and requires Macromedia Flash 6 or later.
