12x12 Hard Sudoku – Vertical

Description:

If you’re ready for a larger board and a steeper challenge, our layout fits the bill. The page displays one 12x12 Sudoku puzzle in a vertical orientation, letting you focus entirely on filling in more cells and more subregions than the standard 9x9. This Hard-level puzzle demands attention to detail, ensuring a satisfying stretch for your logical thinking and deduction skills.

All it takes is a few clicks to get started—our platform is free, so you can generate new puzzles any time you want. If you’d rather explore different difficulty settings, smaller grids like 6x6, or even bigger ones like 16x16, just tap the “edit settings” button. Check the preview, download your PDF, and print a fresh challenge as often as you please. It’s a convenient, cost-free way to enjoy a more expansive take on Sudoku whenever you have some free time or need a stimulating break.

The actual PDF might look slightly different compared to what you see as a preview.
