Crypto Japanese Cave-Bahn
(Published on 18. January 2023, 07:32 by KNT)
Clues outside the grid indicate the sums of connected groups of numbers in the respective row or column, in order, where unshaded cells serve as delimeters between groups.
Draw a totally connected loop network through the centers of all unshaded cells, which may branch or turn, but may not have any dead ends. A clue outside the grid indicates how many times the corresponding line shape (i.e. a cross, branch, straight line, or turn) appears in the corresponding row or column, irrespective of the line shape's rotation.
The letters A to J replace the numbers from 0 to 9, and no two letters may replace the same number. A question mark can be any number from 0 to 9, and for all clues, none may have a leading zero.
A 1-6 example is provided:
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.
