Logic Masters Deutschland e.V.

Rules:

Normal sudoku rules apply.

Renban lines: Digits along a purple line form a set of consecutive, non-repeating digits in any order.

Killer cages: The digits in a cage sum to a number. In this puzzle, the sums must be determined by the solver.

In this puzzle, the sums of the 9 killer cages, modulo 10, form a magic square. In other words: for each sum, take only the last digit. The 9 resulting digits form a magic square. A magic square consists of the digits 1-9 arranged in a 3x3 grid such that every row, column and long diagonal in the grid sums to 15.

Every possible renban line contained entirely within a killer cage has been given.
