12x12 Hard Sudoku – Vertical (2 On Page)

Description:

Looking to ramp up the challenge just a bit more? Our 2 On Page Sudoku Hard 12x12 Vertical setup might be the perfect next step. Two tall 12x12 puzzles are placed one above the other, creating a visually clean layout that’s simple to print. At the Hard difficulty level, you’ll need to bring your A-game for logical deductions, as these puzzles demand careful observation of each row, column, and subgrid. The expanded board size goes beyond the usual 9x9, so you’ll have more cells to conquer and a greater sense of accomplishment when you’re done.

Best of all, there are no fees or hidden costs. Just select your settings, download, and print—instant Sudoku gratification! If you decide 12x12 is too big or too small, feel free to click the “edit settings” button for a different grid size or to adjust the difficulty. Our platform is designed to cater to your puzzle preferences, whether you’re a dedicated Sudoku solver or just looking for a new mental challenge.

I know I'm capable of creating and adjusting the finer details of my own calendar like this in Excel or some other program, but I've been using up my spoons with so many other things that I'm just relieved to stumble across someone who's already done it and made it available for purchase so I don't have to use up any more. I prefer filled versus bound planners because I don't have to risk overhauling the whole planner because I want to redo a few pages.  This also lets me mix and match planner styles, such as using a 15-minute planner template with specific time slots as needed to keep up with appointments and this template that I'm currently reviewing as a lesson planner. I'm using a self-paced course to train for a new career and wanted something that worked for my brain to plan specific deadlines to meet academic goals without getting bogged down by the visual noise of other daily activities. This template has been great for visualizing how many days I have left until the deadline I set and how much I need to get done each day to make sure I meet that deadline.

Not necessarily a review because all of your templates are fantastic and easy to print. I am hoping that eventually you'll make an A7. I know it's tiny, but I'm not that important and don't need to write too many notes.
