Rules
Normal Sudoku rules apply.
Additions and multiplications are Mod 9 and 9=0 is written down as 9.
Clues joining 4 cells apply to both diagonals.
Digits in two cells separated by an X sum to 10.
Digits in two cells separated by a V sum to 5 Mod 9.
White dots join cells with consecutive digits. 1 and 9 are consecutive.
A cell joined by a black dot is twice the other Mod 9. For example mod9 (2 * 8) = mod9 (16) = 7. 7 can join 8.
Digits in a diagonal pointed at by an arrow show the remainder mod 9 of the sum in that diagonal. The digits on a diagonal may repeat.
No negative constraint.
