Japanese Sum Cave Cipher #11: U-Bahn
(Published on 18. January 2023, 07:32 by KNT)
Rules:
Clues to the right and bottom are standard cryptic Japanese sums clues with values 0-9. Same letters stand for same digits, different letters for different digits. As standard, ? stands for any digit 0-9, and no clue may have a leading zero. (Point of clarification: Digits placed in the grid are 1-9)
The empty cells of the Japanese Sums puzzle form a cave: all empty cells are connected and every filled cell is connected to the edge by other filled cells.
Every empty cell must be traversed by a loop network that may branch freely, but may not have any dead ends. Clues to the left and top indicate the number of instances of crosses, branches, straights, and turns of the loop network in the respective row and column. The U-Bahn clues share the cipher with the Japanese Sums.
------
Below is an example and its solution with the digits 1-6 (and a cipher where A-G replaces 0-6). It can be solved here.
The main puzzle can be solved here. Enjoy!
Difficulty should be high 4 stars with some U-Bahn experience, likely 5 stars without.
Solution code: Row 8, then Column 12. C for corner piece, S for a straight segment, J for a junction, and X for a crossing, otherwise the digit.

Definitely my new favorite KNT puzzle. But what is with making me enter a novel for the solution code?

Fantastic puzzle, ended up being one of the more challenging ones for me as I am new to U-Bahns.

This puzzle is a ton of fun, with a lot of surprising deductions.
Also, I think the U-Bahn aspects of the puzzle aren't brutally difficult, so I'd recommend this puzzle even to solvers who are somewhat new to the genre.

I tested this for KNT and found it to be a fantastic puzzle. Really fun and orginial hybrid with a lot of thought-provoking and creative logic. Top 2 in the series for me for sure.
