12x12 Hard Sudoku – Vertical (4 On Page)

Description:

Feed your passion for Sudoku with the 4 On Page Sudoku Hard 12x12 Vertical puzzle set. Each page is stocked with four challenging 12x12 grids, all lined up vertically for an easy-to-print format. You’ll need to stay attentive, as ensuring no repeated numbers across rows, columns, and sub-regions can be quite the mental workout—especially at the Hard difficulty level. This design is perfect for intermediate to advanced players who want a step up from smaller grids.

And don’t forget, you have total control over your puzzle experience. By clicking the “edit settings” button, you can pick another difficulty level or switch to different grid dimensions like 6x6 or 16x16 before downloading. Because it’s all free, you can generate as many puzzle pages as you like without hitting a paywall. Print out your customized layouts for quick mental exercises or extended gaming sessions. Each puzzle promises a sense of satisfaction and accomplishment once those final cells are filled correctly.

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!
