The rules of Killer Jigsaw Sudoku present a wicked twist on those of Jigsaw Sudoku, in the same way that Killer Sudoku is itself an evolution of regular Sudoku.
The aim of the puzzle is to place each of the numbers 1 to 9 into each of the rows, columns and bold-lined jigsaw shapes in the grid, whilst also placing these numbers in such a way that each dashed-line cage adds up to the given total. A number also can't be repeated inside any given dashed-line cage.
There is only one solution, and it can always be reached via sensible logical deduction. Guessing is never necessary.
Solving Killer Jigsaw Sudoku can require a range of tactics - not only those from Sudoku or Jigsaw Sudoku and Kakuro, but also some methods unique to Jigsaw Killer Sudoku itself.
We can supply Killer Jigsaw Sudoku puzzles at different sizes and at a range of difficulties, as well as in either colour or black-and-white. All of our puzzles are either entirely hand-made or have significant manual input into the process.
