My fourth addition to the modulo series. Since the Modulo Yin Yang Puzzle was most fun to set, I did another one with new constraints. Leave a comment if you liked it.

• Modulo Cages
• Modulo Yin Yang
• Fun Modulo 4
• Modulo Yin Yang 2

Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box.

Yin Yang: Shade some cells such that all shaded cells are orthogonally connected and all unshaded cells are orthogonally connected and no 2x2 area is fully shaded or unshaded.

Modulo 3 shading: The value of digits on shaded cells count modulo 3, meaning that the value of each digits is its remander when dividing by 3. E.g.: 7 has the value 1.

Region Sum Lines: Box borders divide each blue line into segments with equal SUMS of VALUES.

XV-Dominos: The VALUES of cells separated by an X must sum to 10. The VALUES of cells separated by a V must sum to 5. Not all Xs and Vs are necessarily given (no negative constraint).

Additionally cells separated by an X and a V must be shaded differently.
