10x10 Hard Sudoku – Vertical (2 On Page)

If you’re searching for a refreshing twist on classic Sudoku, our 2 On Page Sudoku Hard 10x10 Vertical layout is just right. Each page presents two vertically stacked 10x10 grids, striking a balance between the complexity of a larger board and the simplicity of having fewer puzzles per sheet. The Hard difficulty level ensures you’ll need to apply logical thinking and strategy at every turn—no quick wins here. Expect to plan carefully, watch out for repeated digits in rows and columns, and rejoice when you finally place the last number.

Because this service is entirely free, you can generate and download as many puzzle pages as you desire—ideal for both individual practice and friendly competitions. If you’d like a different configuration, simply click the “edit settings” button prior to downloading. From there, you can swap out difficulty levels or try another grid size, such as 8x8 or 16x16. Once you’re happy with your choices, preview and print the final PDF for a satisfying, screen-free challenge anytime you like.
