Prepare a practical Sudoku worksheet pack

This preset creates twelve Medium puzzles, four per page, with answers held on separate pages. Adjust density and level for your group.

Match the worksheet to the lesson

Use fewer, larger puzzles when students are learning a technique and need note space. Use four puzzles per page for independent practice, homework, or a puzzle club.

  • Easy supports first lessons on rows, columns, boxes, and singles.
  • Medium introduces longer scans and candidate elimination.
  • Keep the generated answer pages with the teacher or use them for self-checking stations.

Print a test page before the class set

Confirm paper size, borders, and writing space on one sheet. The New set button creates another batch with the same settings when you need a second version.
