- Digits can repeat on a line if allowed by other rules.
- Cells connected by an X sum to 10.
- Cells connected by a V sum to 5.
- Not all X and V are given (no negative constraint).

I know this is an old one, but I am going back into the archives. This puzzle was ahead of its time. Very well constructed. Impressive setting.
