This puzzle came to life thanks to Gene and him hosting a setting contest around the pairrow constraint(s). I did manage to finish this one in time to submit, and it got a place. 🥹 🥇
Note: Two numbers are in the same residue class modulo D when they have the same remainder when divided by D.

Clarification for the pairrow rule: the empty spaces between grids count. For example, r6c2 is three spaces away from r9c5.

Very nice puzzle!
I was confused as to whether the "non-cell" spaces was supposed to count when crossing between grids.
I eventually found out by the logic of the puzzle, so if it is meant to be like that, good job! Otherwise it would be nice to have clarified more in the rules :)

Yes, they do count, hope the clarification helps.
