Object: Eliminate all Dominoes (except one). (20 fixed variants, 7 randomized variants)
 
You may only click Dominoes that can 'capture' another Domino (see below)!
 
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 after its rotation and sliding the clicked Domino has another Domino 'ahead' of him, then this second Domino will be captured.
The tricky bit is that you can only click a Domino if such a capture of a second Domino is possible!
 
You win when only one Domino is left on the board.
 
The other variants 2, ..., 20 have other starting positions.
Each variant needs only seven moves to solve it, but each is surprisingly difficult!
 
Variant 21 - 27 : Click the board to create a random setup. Depending on the variant, there will be 8, 10, 12, 14, 16, 18, or 20 Dominoes. Eliminate as many Dominoes as possible. (To check how many can be deleted you may let the computer do the task once as a control run).
Thus you can create hundreds more problems of this type. (All 20 fixed variants in this game have been created this way).
