Killer Sudoku
Sudoku Xtra 11 is out now, but I’m holding off the announcement post until it’s available on Amazon.com too. In the mean time, here’s a Killer Sudoku puzzle.
Just place 1 to 9 in each row, column and bold-lined box. Each dashed-line cage should add to the given sum, and you can’t repeat a number in a cage.

Zero Killer Sudoku 9×9 1 puzzleProbably because it sounded cool, or it was invented by someone who didn’t quite speak English, Killer Sudoku puzzles with some of the redundant clues removed are often referred to as ‘Zero’ Killer Sudoku. Or perhaps it’s because there are “zero redundant clues”. In any case, here’s one of those More >

Killer Sudoku Jigsaw puzzle
I’ve recently been working on refreshing the content for PuzzleMix.com, my play-online puzzle site, and one of the puzzle types I’ve been making is Killer Jigsaw Sudoku, where you not only have the jigsaw-shaped Killer regions but also jigsaw shapes instead of the regular 3×3 Sudoku boxes.

Double Toroidal Killer Sudoku Pro 8×8 puzzle
This puzzle certainly won’t be to everyone’s tastes, but it’s a double toroidal killer sudoku pro. Why double? Because there are toroidal jigsaw-shaped Sudoku regions, and there are toroidal jigsaw-shaped Killer Sudoku Pro cages. In other words, some of them wrap around the edges of the puzzle. It’s also More >
