Ten to N
(Published on 28. September 2025, 15:50 by marty_sears)
Rules:
Normal sudoku rules apply.
If a black dot sits between two digits, then one is double the other.
In row N or column N, a clue outside the grid indicates the sum of all the digits that appear in that row or column before reaching the digit N, reading from the end nearest the clue. (The digit N is not included in the sum.)
Solution code: Row 3 from left to right

Very fun, simple rules doing a lot of work. And I love how you always take that extra step in presentation.

It is quite delightful how everything unfolds and finally falls into place in one neat solve path. Very enjoyable puzzle and quite approachable as well. Thanks a lot for sharing this.

So much more mathsy than I'm used to from one of your puzzles. You've been expanding your horizons, I see.

I loved how you pulled the up-to-N in for some simple maths, that made all the difference.

Really enjoyed that usage of Up to N, had a great combination of not being too difficult but still giving you new ideas to discover.
