Logic Masters Deutschland e.V.

Normal Sudoku rules apply. Purple lines are Renban lines; they must contain a set of consecutive, non-repeating digits. Blue lines are Lockout lines; the endpoints (marked by diamonds) must differ by at least 4, and the digits along the line may not be between or equal to the endpoints. Digits along the diagonal indicated by the arrow outside the grid must sum to the given total, and may repeat if allowed by other rules.
