This is the first puzzle in the Ziffular Lines series. The lines in this series have a common modular remainder across pairs of digits. Instead of the remainder of a sum, the commonality is the remainder of a difference.

Ziffular Lines were inspired by the Zipper Lines created by Jaze and the many excellent puzzles featuring them created by the community. One zipper line variant, Ziffers, involves a common difference instead of a common sum. I wanted to expand the possible pairs of digits on a line, so I chose to modify the constraint to compare the difference’s Modular Line remainders (0, 1, or 2) instead of the full difference. This creates a line which is less constrained but still has lots of potential.

Rules:

• Normal Sudoku, Kropki Pairs, and XV Pairs rules apply, along with Ziffular Lines.
• Sudoku: Place the digits 1-9 once each in every row, column, and 3x3 box.
• Ziffular Lines: Each pair of digits an equal distance from the central spot on a Ziffular line have the same DIFFERENCE MODULO 3 (the remainder when the digits are subtracted and then divided by 3). The digit in the central spot has the same remainder when divided by 3.
• For example, 942 is a valid Ziffular line, because 9-2=7, and 7 and 4 have the same remainder (1) when divided by 3.
• Kropki Pairs: Digits separated by a white dot are consecutive. Digits separated by a black dot are in a 2:1 ratio. Not all dots are necessarily given.
• XV Pairs: Digits separated by an X sum to 10. Not all X are necessarily given.

I am a big fan of fantasy adventures, so I decided to add a bit of lore to this puzzle series. The lore is completely optional and will come in the form of a hint for one of the puzzles in the series (not necessarily the current puzzle). All puzzles are unique and solvable without using a hint. The hint will make some difficult deduction a bit easier, but it will not make the puzzle trivial.
