Logic Masters Deutschland e.V.

Rules:

• Standard sudoku rules apply.


• Digits in cages sum to the clue given on the top left of the cage.


• Draw a single loop connecting orthogonally adjacent cells, which does not cross or overlap itself, and visits each of the 9 boxes. For any pair of different cells on the loop, if they have the same digit, then there must be an even number of cells along the loop between them, in each direction. For example, a loop with digits (in order) of 12342145 is acceptable because the 1s, 2s, and 4s are all separated by an even number of other cells, while 123214 is not.


• A yellow dot separates two nonconsecutive digits.
