About these worksheets

Each PDF is three pages: two pages of puzzle grids (4 per page for Easy/Medium/Hard, 2 per page for Expert/Einstein) followed by a full answer key page showing solved cells filled in. The subtle shaded area contains the clues — row clues sit to the left of each row (right-aligned), column clues sit above each column (bottom-aligned). Every 5th gridline is slightly thicker on 10×10 and 15×15 grids to aid counting.

Packs are numbered sequentially within each difficulty. Easy, Medium, and Hard have 37 packs each (8 × 37 = 296 puzzles drawn from the 300-puzzle pool). Expert and Einstein have 75 packs each (4 × 75 = 300 puzzles, fully utilising each dataset).

If you'd rather solve interactively, play online with hints, keyboard controls, and auto-strikethrough when a line is complete.
