Logic Masters Deutschland e.V.

Normal sudoku rules apply.

Gray lines present in the grid are renban lines, meaning the digits on them are consecutive, but they might not be in order.

White squares separate cells whose difference is a multiple of 3.  (This is the same as saying that two cells separated by a square are the same mod 3).

Not all squares are given.

The little killer clue on the diagonal indicates that the sum of that diagonal is 1 more than a multiple of 3.
