Different puzzles per copy — one per student.

Ready for the classroom

Each page has Name, Class and Date lines at the top and four puzzles below. A combined answer key makes marking fast. Choose the difficulty to match your group, from Easy to Expert.

How to play Sudoku on Playoku

Sudoku is a logic number puzzle played on a grid divided into boxes. Fill every empty cell so that each row, each column and each box contains every digit exactly once — 1 to 9 on the classic 9×9 grid, 1 to 4 on a 4×4 grid, and 1 to 6 on a 6×6 grid. Every puzzle on Playoku has exactly one solution and can be solved by logic alone, with no guessing required.
