Make your own Sudoku puzzle book in a minute. Choose how many puzzles you want, from 10 to 50, pick a difficulty and a layout, and PuzzleCraft builds a printable booklet with a cover page, numbered puzzles and every answer at the back.
Every puzzle can be printed or saved as a PDF with a separate answer key. Choose 1, 2, 4 or 6 puzzles per page, switch on Large Print for extra-big squares and numbers, or build a Sudoku book of 10 to 50 puzzles with a cover page and all the answers at the back.
How it works: every PuzzleCraft Sudoku is built from scratch by a generator that fills a complete 9×9 grid and then removes numbers one at a time, checking with a solver after every removal that exactly one solution remains. You will never get a puzzle that needs guessing or has two answers.
Difficulty is rated by the solving techniques a puzzle needs, not just by how many numbers are given. Easy puzzles fall to singles alone. Medium adds naked pairs and pointing. Hard needs triples and box/line reduction. Expert asks for advanced patterns such as the X-Wing and XY-Wing.
Sudoku books make great gifts for grandparents, travel packs for long trips, and quiet-time activities for classrooms and care homes.
