10x10 Hard Sudoku – Vertical

Take your Sudoku-solving up a notch with our layout. This format places a single 10x10 grid on each page in an easy-to-print vertical orientation. The board’s extra cells compared to a standard 9x9 add complexity, and the Hard difficulty pushes you to think critically about each placement to avoid repeats in rows, columns, and subregions.

Because our platform is completely free, you can generate new puzzles anytime without worrying about subscription costs. If you want to explore alternate options—like shifting to a Medium difficulty or choosing a different grid size—simply click the “edit settings” button before downloading. That way, you can preview exactly what your puzzle will look like and save a PDF that suits your preferences. Enjoy a satisfying mental workout on a larger board, all while taking advantage of our hassle-free customization.
