To Eight
(Published on 3. December 2021, 03:37 by Scruffamudda)
Normal sudoku rules apply.
Every horizontal or vertical line of connected digits which sums to 8 is marked with a cage.
No other horizontal or vertical lines of connected digits sum to 8 (including across cage boundaries).
Solution code: column 9

Great new idea & a fun puzzle. I was expecting that the negative constraint could also be used for ruling out a length-3 connected block but only length-2 had to be considered. Maybe a future composition will show new effects with this ruleset?! Thanks for sharing.

This is the kind of puzzle I like, simple rules, however its innovative

I loved every bit of this. Cleaning up the bottom row felt so satisfying.
