Killer Sudoku
Free printable killer sudoku
Sudoku with no starting numbers at all. The grid is divided into dotted cages, and the small number in the corner of each cage is what its digits add up to. No digit repeats inside a cage. That, plus the ordinary sudoku rules, is enough to solve the whole thing — start with the smallest cages.

Killer Sudoku
Sudoku with no starting numbers at all. Dotted cages tell you what each little group adds up to, and no digit repeats inside a cage. That is genuinely enough to solve it.

Printing these
Print at 100 %, not “fit to page” — “fit to page” shrinks the grid and the point size along with it. Ordinary paper is fine; matte holds pencil better than glossy. The answer sheet is a separate file so you can print the puzzles on their own.
Yours to print, as many times as you like. What you may do with these
