Mod 10 Lines Reprised
(Published on 8. June 2026, 05:22 by pagedo)
Normal Sudoku rules apply.
Mod 10 lines:
Add 2 adjacent digits along the line to give the next number which is the Mod 10 of the addition. For example 5 + 1 gives 6, while 5 + 8 gives 3. The line only works in one direction. All digits inside the grid are from the digits 1 to 9.
Cells joined by a V sum to 5.
Cells joined by a white dot are consecutive.
Not all Vs or dots are necessarily given.

@TeddieMilo and @iEtsh
pagedo: I removed the outside hints for the main version of this puzzle. I included the alternative hints version link for those who may need it.

I really enjoy the puzzle and the rule is fun and enjoyable. However, the small layout is killing me. I also donno what's the use of the micro number outside the grid. If u can fully utilize the white space and make the puzzle bigger, would really help an old player who played on a small phone screen.
Thank you so much.
