12x12 Hard Sudoku – Horizontal (4 On Page)

Description:

For those who crave a substantial challenge, our 4 On Page Sudoku Hard 12x12 Horizontal format delivers four expansive puzzles side by side. The 12x12 grid offers a step up from standard 9x9 Sudoku, requiring heightened concentration to keep track of every row, column, and sub-region. Since these are classified as Hard puzzles, each layout promises a satisfying sense of accomplishment once every digit is in its rightful place.

But the fun doesn’t stop there—our service allows for infinite customization at no cost. If you’d like to dial back or amp up the difficulty, just click the “edit settings” button. You can pick from different skill levels or even switch to alternative grid sizes like 8x8 or 16x16. After making your selections, simply download and print your newly created puzzle page. Enjoy the flexibility of exploring various Sudoku styles whenever you want, while fine-tuning your logic and pattern-recognition abilities with each new puzzle set.

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!
