Introduction
For solvers who love variety but also prefer a clean, linear approach, the Six Vertical Puzzles on One Page layout stacks six Medium-level Sudoku boards from top to bottom. This arrangement makes it straightforward to progress steadily through each puzzle without juggling multiple sheets or flipping pages. If you find yourself momentarily stumped on one grid, you can simply slide your attention up or down to the next challenge.
The vertical flow helps maintain a sense of order, especially if you like to work through puzzles in a methodical fashion or if you’re planning to time yourself and track improvements. Since all of our Sudoku puzzles can be downloaded without cost, you can print off entire batches to sustain longer solving sessions or share among friends.

Whether you’re aiming to sharpen your logic or just unwind with a structured pastime, these six stacked puzzles offer a nicely paced way to work through multiple boards in one go.

4x4 Sudoku
The 4x4 is the smallest Sudoku grid, switching to a Medium difficulty level means you’ll see fewer direct placements than in an any easy puzzle. You’ll likely need to scan each row and column more carefully, checking which digits have already been used before filling in the blank spots. This added challenge makes 4x4 a fun warm-up for bigger grids, as you can still finish in a relatively short time while practicing sharper observation.
Because it’s only four rows by four columns, you can quickly identify if you’ve made a mistake—there’s simply less space to juggle. This makes Medium-level 4x4 a neat option for solvers who’ve mastered the Easy version and want a gentle way to push their logic skills a bit further. In group settings or classrooms, it’s a perfect puzzle for quick contests or collaborative problem-solving exercises.
6x6 Sudoku
Stepping up from smaller grids, 6x6 at a Medium difficulty invites you to engage in a bit more thought without the heaviness of advanced logic. You’ll see fewer automatic placements and might need to keep track of which digits fit in certain rows, columns, or mini-boxes. Scanning thoroughly becomes essential, helping you build good habits for tackling larger boards later on.
Many puzzle lovers use 6x6 Medium as a casual brain exercise that’s more involved than the easiest versions but still solvable in one or two sittings. It’s also a natural stepping stone if you’ve already nailed Easy 6x6 and are ready for a somewhat deeper experience. Despite its compact size, you’ll feel the gratifying sense of progress each time you slot in a correct digit, inching closer to that final “aha” moment.
8x8 Sudoku
If 8x8 Sudoku felt like a comfortable size in Easy mode, trying it at Medium can bring new life to these grids. You’ll need to rely on a bit more than simple scanning—perhaps looking for pairs of digits that can only fit in certain spots. However, it remains friendlier than larger boards, making it great for those who want to fine-tune their approach without diving into full-scale 9x9 puzzles.
For educators, 8x8 Medium puzzles provide a healthy challenge to students who’ve moved beyond basic logic but aren’t ready for classic Sudoku’s bigger sub-boxes. It’s also a popular choice for puzzle fans who find 9x9 slightly intimidating. By giving you fewer guaranteed clues, Medium-level 8x8 trains you to think more methodically, paving the way for a smoother transition to the bigger grids down the road.
Classic Sudoku
The classic 9x9 Sudoku format, and a Medium difficulty puzzle strikes a cozy balance between accessible and thought-provoking. You’ll need to use basic strategies like scanning and cross-hatching more effectively, and you might even dip into some light candidate marking if you feel stuck. Still, you shouldn’t run into the multi-step or chain-based logic seen in Hard or Very Hard puzzles.
Plenty of solvers consider 9x9 Medium the “sweet spot”: big enough to be interesting, but not so large or sparse that you’re scratching your head for hours. It’s perfect for daily practice—maybe alongside your morning coffee—or as a casual after-work challenge. Each correct entry adds to a growing sense of accomplishment, and by the time you fill in that final box, you’ll have sharpened your Sudoku skills in a straightforward, manageable way.
10x10 Sudoku
If you’re looking for a twist on standard Sudoku, 10x10 grids at Medium difficulty might just do the trick. They typically use digits from 1 through 10 (or a blend of numbers and letters), forcing you to think carefully about each placement without the puzzle becoming too punishing. You’ll still rely on scanning rows and columns, but watch out for sub-boxes that might be sized differently than the 3x3 you’re used to.
Puzzle enthusiasts enjoy 10x10 Medium as a mild departure from the typical 9x9 routine. The slight shift in layout encourages you to pay attention to unusual sub-box shapes or an extra row of digits, which keeps the logic fresh. Because it’s still classified as Medium, you can expect to stay busy but not overwhelmed—a nice option for when you feel like trying something new without a steep learning curve.
12x12
A 12x12 grid can look intimidating, yet a Medium difficulty puzzle ensures there are enough clues to guide you without resorting to advanced deduction chains. You’ll likely juggle digits (and possibly letters) up to 12, making it essential to keep your notes neat. Each row, column, and sub-region demands a bit of scanning and partial elimination, but you’ll rarely feel completely stuck if you follow the logic carefully.
Many solvers appreciate 12x12 Medium as an expanded puzzle they can linger over—ideal for a relaxed afternoon, perhaps while sipping tea or listening to music. If you’re transitioning from 9x9 or 10x10, you’ll find that 12x12 rewards patient scanning and methodical note-taking. Once you get comfortable filling in a grid this large, you’ll feel a real sense of achievement when the last digit finally slots into place.
15x15 Sudoku
Bigger boards like 15x15 often mean slower progress, but with a Medium setting, you’ll still find enough structure to keep you moving forward. Expect to spend more time verifying that each row, column, and box is consistent, as one slip-up can echo through the puzzle. But that heightened attention to detail also makes completing a 15x15 board especially rewarding.
Some puzzle clubs and enthusiasts lean on 15x15 Medium puzzles for group-solving sessions, where each person can focus on one segment at a time. The process may require more thorough candidate marking than smaller grids do, but it’s far from the steep difficulty you’d see in advanced or expert-level puzzles. This format is perfect if you want a chunkier Sudoku without having to delve into advanced logic methods.
16x16 Hexadoku
Finally, 16x16—often called “Hexadoku”—throws extra symbols or letters into the mix, making it a uniquely large challenge even at Medium difficulty. You might need to mark possible digit-letter combos in each cell, but you won’t usually face multi-step chain logic or guesswork if you methodically scan each row and column.
Fans of bigger boards enjoy 16x16 Medium because it provides that expansive, engrossing puzzle environment without descending into overly complex territory. Each correct placement offers a sigh of relief as you cross out more possibilities. If you’ve ever wanted to explore the broadest Sudoku layout but aren’t into advanced or expert-level hurdles, this puzzle size and difficulty pairing delivers just the right blend of challenge and clear-headed logic.
