@Richard, could you, please, explain this part of the rules: ''Two orthogonal neighbouring cells from different domino pieces must be equal.'' Can two dominos form a square such that one half of neighbouring cells are equal but the other one is not?

Reply: No, two dominos can't form a square in this puzzle. All domino halves touching each other must contain equal digits. In the final grid, all domino's have to be placed like in a regular domino game, with the remaining 'holes' filled with black cells.
Here you can find a small example (puzzle 20)

Great, thank you. That will make it easier to solve.

Great puzzle! There was a lot of novel logic, at least for me. This type definitely has more potential than I first assumed.

Richard, this one is very interesting and quite hard. It took me some time to take the first few notes. After a while I made an assumption in one cell and then - after guessing one number of the solution code ;-) - it took me some more time to finish it. Im going to try if this experience helps me in some other of your Dominos.

Very nice puzzle, though! Thank you!

Because I used the wrong image of this puzzle, it had two solutions. With the new image, it must have a unique solution. I sincerely hope!
