Logic Masters Deutschland e.V.

Standard sudoku rules apply: each row, column, and 3x3 box must contain all the digits from 1 to 9.

Purple lines are renban lines: digits on a line form a set of consecutive digits in any order, without repetition.

Light brown lines are nabner lines: no two digits on a line can be consecutive; there are no repeated digits.

Digits along the diagonal indicated by the arrow outside the grid must sum to the value by the arrow.
