Object: Cover all target squares. 
 
First click anywhere on the board to start a random setup. Zillions will drop eight Dominoes.
 
Click a Domino to rotate it ninety degrees clockwise. If this is not possible because the target square is not empty, then the Domino will rotate 180 degrees. If this is not possible because the target square is not empty, then the Domino will rotate 270 degrees.
After the rotation the Domino will slide as far as empty squares are available.
If at the end of this slide it 'hits' another domino, then this domino will also turn and slide, and so on until no domino is hit after a slide.
Note that such chain reactions make this game different from the very similar game 'Domina 3'.
 
You win if you have covered all target squares. The target squares are marked with orange dots.
 
The other variants have other target squares and/or a different number of dominoes.
Note: Variants 16, 17, 18, 19 have not been solved by the author. Can you do it?
 
Invent your own variants! I am sure the game allows several hundred more challenges...
