Logic Masters Deutschland e.V.

• Normal sudoku rules apply: Place the digits 1-9 once each in every row, column and 3x3 box.
• Serial Killers: Identify 9 Serial Killers in the grid so that there is exactly one Serial Killer in each row, column, and 3x3 box. Each Serial Killer must contain a different digit. A Serial Killer 'kills' every cell orthogonally adjacent to itself, reducing the values of those cells to 0. The values of Serial Killers and any cells that have not been killed are equal to their digits.
• Little Killer: A clue outside the grid gives the sum of the values along the indicated diagonal.
