About the Sudoku Generator

This sudoku generator is part of Tim's Printables, a collection of free printable worksheets and activities for kids, parents, teachers, and puzzle lovers.

The goal is simple: give you a fast, easy way to make custom sudoku puzzle packs. Pick a difficulty level, choose how many puzzles you want, decide how they fit on the page, and print or download a PDF. Answer keys are included, so the sheets are ready to use in classrooms, at home, or just for fun.

Every puzzle is generated to have exactly one valid solution. The generator works entirely in your browser, so there is no waiting and no need to sign up.

Free for Personal and Educational Use

You are welcome to print as many puzzles as you need for personal use, classrooms, homeschool lessons, or after-school activities. If you share the link online, a credit back to timvandevall.com is appreciated.
