Shade some cells in the grid such that all unshaded cells are orthogonally connected, and all orthogonally connected groups of shaded cells touch the perimeter of the grid. Then, enter numbers from 1 to 9 in every shaded cell such that no number repeats in a row or column. Numbers must not be placed in unshaded cells.

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:

Lösungscode: 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.
