Killer Sudoku-X Puzzles by Dr Gareth Moore

Killer Sudoku-X The rules of Killer Sudoku-X, like those of Killer Sudoku itself, present a wicked twist on those of Sudoku-X, since you must not only place each of the numbers 1 to 9 into each of the rows, columns, main diagonals and bold-lined 3-by-3 boxes but you must also place the numbers in each dashed-line cage so that they add up to the given total. No number can be repeated within a dashed-line cage. There is only ever one solution, and it can always be reached via sensible logical deduction. Guessing is never necessary. Solving Killer Sudoku-X can require a range of tactics - not only those from Sudoku-X and Kakuro, but also some methods unique to Killer Sudoku-X itself. I can supply Killer Sudoku-X puzzles at different sizess and at a range of difficulties. All of my puzzles are either entirely hand-made or have significant manual input into the process.
