Logic Masters Deutschland e.V.

Rules:

Normal sudoku rules apply.

Renban - Purple lines must contain a non-repeating set of consecutive digits in any order.

Haze Band - A haze band is a line that may branch in any direction. Where it overlaps another line, that portion is hidden from view; the hidden line still applies its constraint unchanged.

Killer cages - Digits inside a cage sum to the total given in the top left corner of the cage without repeats.
