Sudoku Generator - SudokuPrint

Generate multiple Sudoku puzzles and arrange them neatly on an A4 page.

This app is designed specifically for creating printable Sudoku worksheets. Unlike traditional Sudoku apps, it does not focus on solving puzzles on the screen. Instead, it helps you generate multiple puzzles, arrange them automatically on A4 paper, and export or print the finished page.

It is ideal for Sudoku fans who prefer paper puzzles, as well as teachers preparing classroom exercises and homework.

Multiple Grid Sizes

Choose from several puzzle sizes ranging from 3×3 to 10×10, plus three large-grid modes:

• 12×12• 16×16• 20×20

Create smaller puzzles for casual practice or challenge yourself with large grids and extremely difficult puzzles.

Smart A4 Layout

The app automatically calculates an efficient A4 layout based on the grid size, number size, spacing, and number of puzzles.

It makes better use of the available page space and helps fit more puzzles onto each sheet.

Adjustable Difficulty

Use the slider to set the empty-cell ratio from 20% to 80%.

A lower ratio creates more accessible practice puzzles, while a higher ratio provides a greater challenge. Generate worksheets for different ages, skill levels, and teaching needs.
