Logic Masters Deutschland e.V.

Normal sudoku rules apply. Digits cannot repeat in cages and the digits in every cage sum to 0 modulo N. Cells separated by a white dot are consecutive. Cells separated by an X contain digits summing to 10. Every X in the grid also represents multiplication between the two cells it separates, with their product modulo N being placed to the right of the equals sign. The number N is the same throughout the grid and is not given. The solution does not require any cells to contain zero.
