About these worksheets
Each PDF is three pages: two pages of puzzle grids (four per page, with every cell showing its starting number) followed by a full answer key where the cells that should be shaded are filled black. All puzzles are computer-verified to have a unique solution.
Packs are numbered sequentially within each difficulty. Pack 01 contains puzzles 1–8, Pack 02 contains puzzles 9–16, and so on up to Pack 37 (puzzles 289–296). Each difficulty has 300 distinct puzzles total.
If you'd rather solve interactively, play online with hints and step-by-step solutions. Or read the Hitori rules guide to learn the shading mechanics.
