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.

Regardless, each PDF is straightforward to preview, download, and print. Dive in and let the puzzle-solving begin!

This was definitely not what I was expecting. Although there is a plethora of options i was hoping to just download one huge file and be able to edit and sort without needing a hyperlink to access them as I am not very tech savvy.

Missing one star because I made an error not because the seller did. I thought I could edit this item in a program I use but I can't hence, the 4 star over 5. I would have given 5 star if I could use my favorite editing program.
