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 am so happy to have found such a comprehensive planner for my Kindle Scribe. The included templates in the Scribe leave a lot to be desired. This planner is incredibly detailed and provides me with all that I need and more to organize my life. I cannot wait to play around with it some more. I would buy again in a heartbeat!
