It was a... questionable choice on my part not to use a domino tracker on the side, especially considering I was solving on paper anyway ._. But I made it! First try no mistakes xD

What a brutally challenging puzzle! After the break-in also it never gave up and till the very last when the last two dominoes fell in place, this just did not relent. Each digit was hard fought. Made so many mistakes which seemed so silly in hindsight. The discovery of logic at each stage was so satisfying and appeared very obvious later on. Thanks a lot for sharing yet another masterpiece.

Magnificent puzzle! Fraught with danger throughout - had to backtrack several times to fix some careless mistakes.

Phew, I think it’s been a long time since I have made so many mistakes in a single puzzle ! Kept overlooking some possibilities at every turn, and of course I always took the wrong turn... But it was very satifying to finally see all the dominos fall into place ! Thanks :)

Great puzzle, was really challenging for me.

@KNT yeah I just came to the same conclusion. Will figure out why I'm breaking the puzzle, then :-)

@Piatato if 1-2 and 2-1 were different dominos, we’d have 81 different dominos to place… two cells each would mean 162 cells of the 144 cell grid are dominos ;)

Amazing puzzle. Glad I persisted where the solving path got really narrow. Thanks.
