I've created even more free sudoku printables, by popular request. The 100 puzzles below are in a large, one-per-page format. Choose from easy, medium, hard, or very hard level of difficulty.
The solutions are printable as well. Feel free to print and solve as many of these sudoku puzzles as you like.
Each sudoku printable page has one zoomed-in puzzle. The large puzzle size provides lots of room for you to tag guesses in cells or make notes along the side of the puzzle. Anyone with poor vision should find these puzzles easy to see.

As mentioned, the sudoku puzzles available here are one to a page, unlike the other collection. I thought four-sudoku-to-a-page was a good idea at the time.
Cramming four on a page does have its advantages. The main benefit is you get four sudoku puzzles one sheet, which saves paper.
On the down side, I had to shrink those puzzles so all four would fit on a single page. This doesn't leave much room for annotating each puzzle with tag numbers as you try to solve it.
Also, the four-to-a-page can feel a little cramped. Folks with eyesight problems may have trouble reading the numbers on those.
The new larger sudoku printables here correct all those issues. I hope you enjoy solving them.
Are you the publisher of a newsletter, bulletin, newspaper, or magazine? Include a sudoku puzzle or word search puzzle in each issue. Your readership will love it!

For those new to sudoku, I'll quickly go over the rules.
Note: To learn powerful strategies for solving sudoku, see Kevin Rush's free guide here. You'll learn advanced techniques such as Ghosting, RC Counting, Tagging, and Line Checking.
The rules of sudoku are straightforward. Enter a number 1 through 9 in each cell of the puzzle such that no number is repeated in any row, column, or 3-by-3 square.
The puzzle is solved once you have filled in all the small squares following this rule. Every sudoku puzzle has only a single solution.
Sudoku puzzles consist of a large square divided into a 9-by-9 grid. There are nine rows and nine columns. Each row has nine small squares. Each column has nine small squares. These small squares are also known as cells.
The grid is further subdivided into 3-by-3 boxes. There are nine of these. (See the sudoku puzzle image at left as an example.)
As I mentioned above, you need to enter a single digit 1 through 9 in each of the 81 small squares in the puzzle. The number 0 is not used.
I recommend using a pencil with an eraser, since it's quite typical when solving sudoku puzzles to make a few errors along the way.
You are allowed to make notes and other marks on the sudoku printable. One common strategy is to enter guesses in small writing in the cells. This is known as tagging.
Another is to list the numbers 1 through 9 on the side of the puzzle. Once you've found all instances of a number, cross that number off your list. That way you won't waste time checking numbers you've finished searching. See Kevin Rush's sudoku strategy guides for a detailed explanation of this and other tricks.
Sudoku is one of my favorite number puzzles. It's great for sharpening brain skills such as concentration and numerical reasoning. I hope you enjoy this collection of 100 large-size sudoku printables.
