How the levels are set

On this site the level is the number of given numbers: easy gives 45, medium 35 and hard 27. Fewer givens usually take longer to solve, but the solving methods a puzzle needs can differ between two puzzles of the same level. Every puzzle is checked to have exactly one solution.

Print a puzzle pack

The ready files contain ten different puzzles, followed by ten numbered answer keys. Print pages 1 to 10 for the puzzles, and keep pages 11 to 20 for the answers.
