Summation U-Bahn #6: Liar
(Published on 30. November 2024, 09:00 by Agent)
Rules
- Draw a loop network through the centers of some cells, which may branch or turn, but may not have any dead ends.
- Assign each line shape (irrespective of rotation) a digit from 1 to 4 as follows: corner = 1, straight line = 2, branch = 3, cross = 4.
- Clues outside the grid represent the sum of "digits" in each contiguous sequence of cells visited by the loop network, in the order of appearance from left to right or top to bottom. Consecutive sequences must be separated by at least one cell not visited by the loop network.
- For each row and each column where clues are given, one set of clues is complete and correct. The other set of clues must be a lie, that is, either the amount of clues is incorrect or the numerical value of one or more clues is incorrect (or both).
- Each letter represent a different number. A "?" may represent any number, including two-digit numbers.

Solution code: For each row except the last, from top to bottom, the number of lines leading down from that row.

[You sneaky Agent...]
Another beautiful and clever puzzle! The previous entries did help to get familiar with some patterns in here, the later half of the solve especially was deliciously delightful to work on!
Don't make me pick my favorite in the series, it's like choosing between the favorite childs (lol)

There's nothing else to say; SUB is the best series of puzzles of all time.
It's also incredibly fun to feel myself getting better at solving these.

It is equally rare for the end of a U-Bahn puzzle to outshine the start, especially when the start is remarkable already. Yet this one achieved perfection, especially the last four letters: sinister but ingenious.
Thank you Agent! Eagerly waiting for the next masterpiece in this series.

Great puzzle again ! On the easier side for me compared to previous entries. Definitely helps to know some patterns learned from solving the other puzzles first. Thanks :)
