Logic Masters Deutschland e.V.

• Hexagonal Kakuro: Place a digit from 1 to 9 in every empty cell such that digits do not repeat in an unbroken "row" (along any of the three directions in which cells share edges) without any black hexagons separating them.
  • Numbers in a black hexagon indicate the sum of digits that clue sees in the indicated direction, up until either the next black hexagon or the edge of the grid, whichever is encountered first.
  • A question mark may represent any number.
• Slingshot: If a cell contains an arrow, then the number in the cell connected to the tail of the arrow must appear N cells away in the direction of the head of the arrow, where N is the digit in the cell with the arrow clue.
  • If the Nth cell in the indicated direction is a black hexagon, the number at the tail of the arrow must be one of the given clues in that black hexagon (a slingshot cannot send a number to a hexagon with no given clues).
  • If there is a black clue cell at the tail of an arrow, and it has multiple given clues, the solver must deduce which of those clues is the number that the slingshot clue references.
• Clarification: The number that a slingshot clue points to does not necessarily have to be the first (or last) instance of that number seen in the indicated direction.
