Very nice puzzle, thank you. After fully coloring the grid and all was left was to switch colors to numbers, I managed to fumble and ended up putting my 4's and 6's in the wrong way around and broke the final sandwich clue :)

@Christounet: Thank you! Also, this is a good observation, because I really enjoy discovering little peculiarities like this and building a puzzle around it. And in fact, I am a mathematician. :)

Very nice ! I like that kind of puzzle where you have to think about the clues and negative constraints outside the grid before you even start to put anything in the grid. As in mathematics, when you have to discover a theorem that's only valid in a given set with its basic properties. I noticed you tend to do that a lot in your puzzles.

It's absolutely extraordinary that this puzzle has a unique solution! It took me a while because I got stuck somewhere in the middle but that made it even more rewarding when it finally cracked :-)

This was a fantastic puzzle, and on the easier side as your puzzles go, I found. It's interesting how so few clues are required for a unique solution with this ruleset.

Took me over 3 hours, but managed to solve it and really loved the logic. Clever break-in and interesting path for the middle solve.

A beautifully smooth, thematic solve, resonant with peculiar little "echoes" everywhere.

A very hard but fun puzzle with a fabulously ingenious break-in. It takes me way to long to admit, but I am chuffed to be able to solve it at all :-) lots of staring aimlessly before dim bulbs light up...

Being able to solve a Phistomefel puzzle is one of the pure joys of life !! Messed up the endgame on first attempt, but came back today and got thru. What an elegant puzzle ! Thanks, @ Phistomefel :-)

On my first attempt I made a mistake somewhere, but I started over and persisted, and the second attempt went much smoother! What a lovely puzzle. :D

Thanks a lot for the warm feedback, folks! I am really glad if you found the solving path interesting.

Very cool puzzle. Challenging as usual, but nothing inhumanly hard this time :-)

he's done it again! what a sublime work of telegraphing each step so tightly that it almost feels like the setter is holding your hand and teaching you the secrets of the consequences of the constraint... just brilliant

Beautiful puzzle as always.

Incredible and wonderful opening sequence! I didn't expect to see the difficulty suddenly ramp up after that, but once I spotted the one trick, everything got resolved beautifully ;)

Very nice combination of rulesets. Congrats :)
