How do you stack up?

Slide colored cubes down the board. When you've created a group of three or more, it disappears. Special cubes allow you to make stacks, absorb cubes and change their color, and more.

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

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

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.
