Ever since I published Odd Fives and Even Sevens, I've been thinking about creating a puzzle with two "special" digits. Recently I discovered that this might work with low/high digits, where a 1 can't touch another low digit, and a 9 can't touch another high digit, although this rule is surprisingly restrictive.
Rules:
- Normal sudoku rules apply.
- Every cell orthogonally adjacent to a 1 must be at least a 5 and every cell orthogonally adjacent to a 9 must be at most a 5.
- Cells connected by an X must sum to 10. Cells connected by a V must sum to 5. Digits connected by a white dot are consecutive. Not all Xs, Vs and dots are given.
Lösungscode: Row 7

I agree it's surprising how restrictive this rule can be. It creates quite interesting interactions. Very nice puzzle!

Probably closer to a 4* than a 3*, but very beautiful logic. I was surprised it worked, but it did. Loved it, thanks!
