Logic Masters Deutschland e.V.

Rules:

• Normal sudoku rules apply.
• Along the negative diagonal, digits may not repeat.
• Each purple line contains a set of non-repeating consecutive digits, in any order.
• Box borders divide blue lines into segments with equal sums.
• Adjacent digits on a green line differ by at least 5.
• Grey lines are palindromes, i.e. they read the same forwards and backwards.

Clearly, some lines touch each other. However, lines do not intertwine.
