Please read the instructions carefully as there is a slight spin on a traditional negative constraint.
Normal Sudoku Rules.
Disjoint Groups - Digits cannot appear in the same position in a different box.
XV - Digits separated by a V sum to 5; digits separated by an X sum to 10.
While all V's are given; not all X's are necessarily given.
The grey circle is an odd digit.
Also, if two orthogonal cells sum to 9 they must be in a given 2 cell killer cage. So no two orthogonal cells sum to 9 unless they are in a given cage.
