Logic Masters Deutschland e.V.

Normal sudoku rules apply. Place the digits 1-9 in each row/column/box without repeating.

Anti-King - Same numbers cannot be adjacent diagonally.

Killer Cages - Digits may not repeat in a cage, and the cells within the cage will sum to the marked number, if applicable.

Double Arrow - The sum of the values on a red line will equal the sum of the values in the two circles on either end. **All Double Arrow clues are straight lines. If two double Arrow clues intersect, the sums of both clues will be the same.**

Quadruple - A white circle on a vertex must have each of its numbers in the adjacent cells.
