Logic Masters Deutschland e.V.

Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box.

XV-Dominos: Cells separated by an X must sum to 10. Cells separated by a V must sum to 5. Not all Xs and Vs are necessarily given (no negative constraint).

Between Lines: Digits placed on Between Lines must be strictly between the digits placed in the circles at the ends of those lines.

Digits along the marked diagonal do not repeat.

Another constraint first time for me as a fairly new setter. Leave a feedback comment on the experience.
