Hungarian Tapa / Roller Coaster (2)
(Published on 28. September 2022, 16:37 by KNT)
Cells inside the grid with clues cannot contain numbers, and they indicate the sums of all contiguous groups of numbers in the (up to 8) number cells that directly surround the clue cell. Empty cells serve as the delimeter between groups.
A loop that travels orthogonally from cell center to cell center must be drawn such that it visits every empty cell. On a single round trip of the loop, no cell is visited more than once. Clues outside the grid to the left indicate the sums of numbers on each horizontal stretch of the loop in that row, in order. Clues outside the grid to the top indicate the sums of numbers on each vertical stretch of the loop in that column, in order.
For all types of clues, a question mark can replace any number from 0 to 9, but no double digit clue may have a leading 0.
SudokuPad
Solution code: Row 3, with S for straight segment of loop, and L for a turn of the loop. If a cell has both a digit and loop, enter the digit first.

Amazing! Indeed very hard, but it never felt like a single step was too hard. There were mostly just a lot of little steps.

Incredible construction! One of my favourites of yours for sure, which says a lot. Thanks :)

Really good puzzle! It's nice that the puzzle has a constant difficulty during the whole solve

My goodness, that took me forever !!
I had to reset it at almost two thirds, because I was getting no more progress, and it made me realize I had done a terrible arithmetic in column 1... Anyway, starting over made me appreciate even more the subtle entry point to this puzzle. Despite what you said to me about the quality of this puzzle not reaching your usual standards, I can tell you I enjoyed every minute of the solve (and that was plenty minutes, believe me) and several of the deductions felt very satisfying ! Hungarian tapas are such treacherous clues in this puzzle, because one can easily forget a clue once it's surrounded by digits, shading, segments of loop... Gotta be extra careful when you solve a puzzle like this one... And setting it, well, feels like some kind of wizardry to me !

Hands down the hardest puzzle of yours on this portal imo. Solving this felt like a long scavenger hunt with plenty of rewarding deductions along the way. Amazing construction to come up with something so large and intricate. Thanks KNT!

Magnificent! Several hours of pure enjoyment, inching forward slowly deduction by deduction. Really well balanced solution path that is never tricky yet maintains its challenging nature all the way to the end. Thanks for the wonderful puzzle KNT!

Loved it! This puzzle would be up there among my favourite Wichtels for its originality, intricacy and size if it were one, which is probably the best compliment I could offer you. Can certainly confirm there is significant room for errors to be made, of which I discovered several! But there is definitely a very fair and logical path through it all.
Thank you for setting this - you should go overboard more often when you come back ;)

What a brutal, brutal marathon! The grid keeps on giving once the initial start is found though, so that you always are at the right place to look :D

Enjoy the break.
But not for too long.
