Hungarian Tapa / Roller Coaster (1)
(Published on 23. September 2022, 20:45 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.

I've never before felt so rewarded every time I discovered another rule that I'd overlooked while skimming through the ruleset. XD

This was just fascinating stuff ! I had trouble getting acquainted with the ruleset at first because of all I had to keep in mind, but once I did, it was a real treat of a roller coaster ride ! Now I'm off to try the bigger one !! Buckle up ! :)

Great fun as usual ;-) And not too difficult. Still challenging enough to keep in mind all rules.

Updated link due to some bugs in Penpa+ regarding resizing the grid

That was great! Also, next time I won't forget the rule about the loop going through all unshaded cells.
