Modular Lines 2
(Published on 22. April 2022, 03:08 by FullDeck-Missing)
Normal killer cage rules apply: digits in cages cannot repeat and must sum to the number shown in the upper left corner of the cage.
Modular lines: every set of three sequential digits along a line must contain a complete set of residues modulo 3, i.e. one digit from {1,4,7}, one from {2,5,8}, and one from {3,6,9}. Digits on two-cell lines cannot be from the same residue set. Digits may repeat on a line if allowed by other rules.
Another puzzle with a similar rule set:
- Modular Lines 1 // Modulare Linien 1 (3-star)
Solution code: Row 9 (from left to right) followed by Column 5 (from top to bottom); 18 digits with no spaces.

I loved it, haven't done this mod3 lines, so took a second to understand, but after that, what a ride!
>> Thank you! As far as we know, this is a new constraint but JC Godart and Raumplaner have both been using it as well since we introduced it. If you're looking for more puzzles with this constraint, we have one already on LMD and several more that we'll be uploading over the next few weeks.
