15x15 Hard Sudoku – Horizontal

Description:

Looking to tackle an expansive board with plenty of horizontal room to jot down notes? Our puzzle is perfect. Occupying the entire landscape orientation, this single, large-scale grid demands advanced logic skills and meticulous planning to fill in every slot. The Hard difficulty level ensures that even the most experienced Sudoku solver will find something to sink their teeth into.

Since our service is entirely free, you can print off endless variations—ideal if you’d like to share them at puzzle clubs or keep a personal stash for future use. If you prefer a different approach, use the “edit settings” button to swap grid dimensions or difficulties. Maybe you’re ready for 16x16, or maybe you want to step back to an easier level. Regardless, each PDF is straightforward to preview, download, and print. Dive in and let the puzzle-solving begin!

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

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!

the PDF's work well with my Onyx Note Air, and they are easy to edit and mark up. The tool for customizing is great with a ton of options.
