16x16 Hard Sudoku – Horizontal (4 On Page)

Description:

For the ultimate test of Sudoku prowess, our 4 On Page Sudoku Hard 16x16 Horizontal collection is sure to impress. It features four enormous 16x16 puzzles aligned in one row, each one requiring exceptional focus to solve. The expanded format means more rows, columns, and subgrids, which translates to a deeper level of complexity. At Hard difficulty, only the most persistent solvers will find themselves breezing through.

Even better, everything on our site is free, so you can generate and print unlimited puzzle sets for personal use, educational purposes, or puzzle-loving friends. If you decide to try smaller boards or different difficulties, just tap the “edit settings” button. You’ll have access to options such as 4x4, 6x6, or 9x9, each with five difficulty levels ranging from Very Easy to Very Hard. Once you’ve selected your perfect setup, preview and download a printer-friendly PDF. Dive into these colossal challenges for a rewarding exercise in logic and patience!

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!
