About these worksheets
Each PDF is three pages: two pages of puzzle grids (four per page, with the clue numbers in their cells) followed by a full answer key where every rectangle is outlined in thick black over the standard grid. 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 Shikaku rules guide to learn the area-and-factorization mechanics.
