Liar, Liar, Up to N’s on Fire
(Published on 6. November 2026, 11:05 by sujoyku)
I’d like to thank NEWS, Calvinball, PrissyP and Marty for testing and wish you joyful solving!
Rules:
- Normal sudoku rules apply, i.e. each Row, Column, and 3x3 Region has to contain the digits from 1 to 9 once each.
- Liar Cells: Each Row, Column, and 3x3 Region contains one liar cell, whose real value is different from its digit.
Every liar cell contains a different digit from 1 to 9.
Every liar cell has a different value from 1 to 9.
- Up to N-sums: A clue outside the Row or Column N indicates the sum of all values up to the first cell seen from the clue that contains the value N. (The value N itself is not included in the sum.)
Here you can solve the puzzle online:
Solution code: Values in Row 8 from left to right (9 digits in total)

Very nice combination of rules, a lot of deep thinking! 80 minutes for me, but I could've finished faster if I hadn’t been distracted by work...

Fabulous. Struggled at first as I’d not realised that the rule restricted where the N values went but once I realised that, the puzzle was a blast to solve. :)

Excellent puzzle! Very tricky, especially compared to most of your other puzzles. Great solve path. I really liked how the liar digits and values resolved. Liar cells are a fantastic constraint and just keep on giving. Thanks!

You are right. This is a bit harder than my usual 2-3* sweet spot.
I am glad that you liked it.

A beautiful combination of liar cells with sujoyku's trademark constraint, 'up to N'. Some moments I found quite tricky, but everything flows moothly once you ask the right questions :)

Thank you, Marty! Your setting is an incredible source of inspiration. It is great to hear that you enjoyed my take on your variant.
Kind regards, sujoyku
