Liar Japanese Sums #1

(Published on 21. December 2022, 18:27 by Niverio)

These last few months I have been a little inactive, or it seemed so. It's mainly because I have been testing a lot of puzzles privately and setting puzzles for different projects which were not suitable (or allowed) to appear on LMD just yet. But I haven't gone anywhere.

This next puzzle I am publishing right now is the start of a series of puzzles I intend to set using this new ruleset, inspired by this awesome KNT puzzle. It has been my favourite puzzle I solved this year, and although that puzzle is extremely complex, the core ideas of it have huge potential and they can be simplified quite a bit, which I have tried to do here with this first iteration of puzzles. As I set more, I will be incorporating either other puzzle genres, or sudoku variants into it as well (and probably leave the strict boundaries of Sudoku itself). But don't get the wrong idea, this puzzle is still not a pushover by any means. :) Hope you enjoy!

Rules:

  • Sudoku: Normal Sudoku rules apply. Place digits 1-9 in every row, column and 3x3 box.
  • Liar Japanese Sums: Shade some cells in the grid such that clues outside the grid indicate the sums of the continuous blocks of unshaded cells in that row or column. At least one shaded cell must separate the blocks. For every clued row or column, 2 different sets are provided (Left / Right for rows, Top / Bottom for columns.) One set is correct, with correct sums in the correct order.(Always left to right or top to bottom.) The other set is a lie. Which sets are correct must be determined by the solver.
  • Empty rows and columns simply indicate that there are no clues provided for that row or column.

Puzzle Links: You can solve the puzzle in F-Puzzles, CTC or in Penpa+. CTC and Penpa versions have answer check included for correct number placement.

Solution code: Number of shaded cells in Column 5, followed by the digits of Column 5 (10 digits, no commas or spaces.)

Loved this ambiguity puzzle ! I'm really starting to get the sense of how one needs to approach a japanese sums puzzle. This one was intimidating at first, but surprisingly easier than I thought. Thanks !

Would a bottom clue both be read top to bottom and placed in the grid top to bottom?

~Yes, that's correct
