Description:
For the ultimate test of Sudoku prowess, our 4 On Page Sudoku Hard 16x16 Horizontal collection is sure to impress.

The expanded format means more rows, columns, and subgrids, which translates to a deeper level of complexity.

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.

Absolutely blown away by the features and customization options for this planner. It truly lets you build your dream planner! So well thought out and designed. I hated having to switch back and forth between files on my reMarkable. Now I have a planner and notebook that I never have to exit, because everything is in one place and well organized. The hyperlinks are so well done! I will come back for this one next year for sure! I would love the addition of some copy and paste stickers in the future. I was able to get some of those elsewhere and build a sticker section into the planner. But it was a bit time consuming. Would love to have this included one day. Highly recommend this planner!!! Well done!
