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.

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!
