Logic Masters Deutschland e.V.

Rules:

• Normal Sudoku rules apply.
• The zig zag lines are Palindromes. The numbers read the same frontwards and backwards.
• The total of the digits along an arrow must appear in the arrow's circle.
• Cells separated by a white dot have a difference of one while cells separated by a black dot have a 1:2 ratio. Not all dots are given.
• The numbers in a cage must sum to the number in the top left corner of the cage if given. Numbers may not repeat within a cage.
• Numbers outside the grid are little killer clues. The total of the digits along the diagonal must add up to the clue given.
