About these worksheets

Each PDF is three pages: two pages of puzzle grids (four per page, or two per page for the larger Expert and Einstein grids) 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, solvable by logic with no guessing.

Packs are numbered sequentially within each difficulty. Easy through Hard fit 8 puzzles per pack (Pack 01 = puzzles 1–8, up to Pack 75 = 593–600); Expert and Einstein use larger grids, so they fit 4 puzzles per pack (Pack 01 = 1–4, up to Pack 150 = 597–600). Each difficulty has 600 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.
