To open the door, you must slide each block into place. Click on a block and it will slide down the lined path to its designated spot. Once all blocks are in their proper places, the door will open! Click on the door to move to the next level.

Blocks can't collide with each other - so plan each move carefully!

In later levels, spikes will appear on the paths. Each time a block moves, some spikes will disappear while others reappear. So if the spike was visible, it will lower into the hole and vice versa.

If you want to restart the level, click on the arrow in the upper right corner of the screen.
