I was stuck until I got gravity assist from CTC. Very dense and beautiful sudoku.
Thanks Mark. Triple thanks Myxo.

This may be the most challenging 6x6 I’ve ever solved, but that’s partially because I had never encountered numbered rooms before, and I kept getting my numbers mixed up. Still… I solved it, but I couldn’t for the life of me say how, exactly. Every digit felt like a win! I also learned a few things that I didn’t know before and, for that, I thank you.

Fun puzzle with good logic. Tricky in spots for sure but once I remembered the trick with anti-knight in a 6x6, it made things a touch easier
