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.

There are so many items to look at, choose from, and decide which to download and printout. It is incredible! I think I am a bit addicted to planners and planner pages, and accessories. I have bought several, made my own, and am always looking for more. I am a stationary junky, I can admit it. Planners are just part of that. With so much to choose from, this buy will keep my addiction satisfied for a few minutes. (kidding, for awhile). I love what see so far. Now to print some out!
