How to play Sudoku
Fill the grid so that every row, every column and every 3×3 box contains the digits 1 to 9 exactly once. The digits printed in bold are your starting clues.
Start where the grid is busiest: a row, column or box with only one or two gaps often gives an answer straight away. Pencil small candidate numbers in the corners of cells when you get stuck.
How our difficulty levels work
We grade every puzzle by solving it the way a person would and recording the hardest technique it needs, rather than just counting clues.
Easy puzzles need only singles: a cell with one possible digit, or a digit with one possible home. Medium puzzles have fewer clues or need you to spot a digit locked into one row of a box. Hard puzzles need pairs and triples. Expert puzzles need patterns such as the X-Wing, Swordfish or XY-Wing, but never trial and error.
Printing tips
Every PDF is laid out for both A4 and US Letter. Choose “Actual size” or “100%” in your printer dialogue rather than “Fit to page” so grids stay square.
The puzzles are black on white with thin rules, so they print cleanly in greyscale and use very little ink. Answers come in a separate PDF, so you can print the puzzles now and keep the solutions for later.
