Printing FAQ
What makes Killer Sudoku different on paper?
Each puzzle adds dashed cages with a small sum in the corner: the digits inside a cage must be different and add up to that sum. The printable keeps cage lines crisp on any printer.
Are the cage sums readable at print size?
Yes — cells are at least 14mm and cage sums print at a guaranteed-legible size, designed for comfortable solving away from the screen.
Does the answer page show the cages too?
The answer page shows the completed grid for quick checking; the cage layout is on the puzzle page, so you can verify any cage against the solution digits.
