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.

I bought this to get templates for my Supernote. There are a ton of options for all of my devices. The Supernote png is not sized for the new Manta. I was able to resize the pages myself and they look amazing on the device. The only other minor inconvenience is that it isn't always clear what I had bought access to and what had an additional price tag on it. Overall, these are minor things and I am 100% enjoying the amazing variety, clean graphics and customizations that are included. I highly recommend for anyone whether you have one device or many that you are downloading for!
