100 Free Easy Sudoku Printables

I've put together 100 free easy Sudoku printables for beginners and anyone who enjoys a gentle pencil-and-paper challenge. Each puzzle has one large grid per page and a separate answer key. Choose any puzzle below to print it or save as a PDF. All free, no signup required.

Easy Sudoku puzzle 1 with large squares and clear 3 by 3 boxes

To print or save a puzzle: Select a numbered Puzzle link below, then choose Print This Page. In the print window, select your printer or a PDF option. The Solution link beside each puzzle opens its answer key. Puzzle and solution pages open in a new tab.

All 100 puzzles on this page are Easy. Puzzles #001-080 offer a gentle start with plenty of numbers already filled in. Puzzles #081-100 give you a little more challenge: fewer starting clues and more squares to work out, using the same basic solving techniques. The large squares leave room for pencil marks, and the answers stay on their own pages.

Easy Sudoku Puzzles 81-100: A Little More Challenge

Ready for a step up? These 20 puzzles have fewer starting clues, so you have more squares to fill and may need to scan the grid more carefully. Each still has an Easy rating and can be solved using single-candidate techniques and hidden singles, explained below. The numbers within this group are for reference, not a strict difficulty ranking.

How to Solve Easy Sudoku

A Sudoku grid has nine rows, nine columns, and nine smaller 3 x 3 boxes outlined with thicker lines. Your job is to fill every empty square with a number from 1 through 9, following three rules:

Each row must contain all nine numbers, with no repeats.
Each column must contain all nine numbers, with no repeats.
Each 3 x 3 box must contain all nine numbers, with no repeats.

The numbers already printed in the grid are your starting clues. Leave those in place. You do not add, subtract, or calculate anything; the numbers act as symbols whose positions you work out by elimination.

How I Check and Rate These Easy Puzzles

I checked every puzzle for exactly one solution and confirmed that its separate answer key matches. I also verified that all 100 can be completed using basic singles techniques:

Single candidate: Only one number can fit an empty square after you check its row, column, and 3 x 3 box.
Hidden single: A missing number has only one possible square within a row, column, or box, even if that square appears to allow other numbers.

For an additional check, I ran the complete collection through HoDoKu 2.2.0 with its default difficulty settings. All 100 received its Easy rating. HoDoKu considers the solving techniques used and their combined score; difficulty labels can vary between publishers.

Puzzles #001-080 have more starting clues. Puzzles #081-100 give you more squares to solve and a little more searching practice, while staying within the same singles-only standard. None requires guessing, pairs, X-Wings, or advanced chains. Easy still takes practice, so take your time and rescan the grid after each discovery.

A simple routine for getting started

Look for nearly finished rows, columns, or boxes. If just one square is empty, work out which number from 1 through 9 is missing.
Check a square against all three rules. A number may be missing from its row but already present in its column or box. Rule those numbers out.
Look for the only place a number can go. Pick a number missing from a box. Numbers already in the crossing rows and columns may rule out every empty square except one.
Scan again after each answer. A number you just entered may make a nearby square solvable. Small discoveries often lead to several more.

Try Three Opening Moves from Puzzle #001

Here is the actual starting grid for Easy Sudoku #001. If you would rather solve it entirely on your own, skip this example. Count rows from top to bottom and columns from left to right.

Starting grid for Easy Sudoku 001. The first row reads 2, blank, 3, 1, 7, blank, 8, 4, 6.

Find the two missing numbers in the top row. It already contains 2, 3, 1, 7, 8, 4, and 6. The missing numbers are 5 and 9, and the empty squares are in columns 2 and 6.
Check the top-left 3 x 3 box. There is already a 5 in that box, at row 2, column 1. So the empty square in the top row, column 2, cannot also be 5. It must be 9. That leaves 5 for the other empty square in the top row, column 6.
Now check the top-left 3 x 3 box. With that 9 entered, the box contains 2, 9, 3 / 5, blank, 4 / 8, 6, 1. Its only missing number is 7. Write 7 in row 2, column 2.

That's three squares filled using only the numbers already on the page. Continue by scanning for another nearly complete row, column, or box. You can open the separate solution for #001 whenever you want to check your work.

What to Do When You Get Stuck

First, move to a different part of the grid. It is easy to keep staring at one square even when a simpler move is waiting elsewhere. Try scanning for one particular number throughout the nine boxes, then switch to another number.

If you need pencil marks, write the possible numbers lightly in an empty square. For example, a small "3, 8" means either number still fits the row, column, and box. These are possibilities, not answers. Cross one out when a new entry rules it out.

If a square seems to have no possible answer, or a number appears twice in a row, column, or box, check your recent entries. Every number must satisfy all three rules at the same time. An answer that fits the row can still be wrong for the box.

I keep the solutions separate so you can decide how much help to use. Check one troublesome square and return to the puzzle, or compare the whole grid after finishing. For a longer illustrated lesson, see Kevin Rush's Sudoku Instructions: How to Play and Win here on my site.

Printing Your Sudoku or Saving It as a PDF

Open an individual puzzle before printing. Use its numbered Puzzle link above to open the large printable sheet, or the Solution link beside it for the matching answer key.

For a paper copy: Choose Print This Page, select your printer, and check the preview. Use portrait orientation. The sheet is designed for US Letter paper; if you use A4 or see an edge cut off, choose your print window's fit-to-page setting.
For a PDF copy: Open the same print window and select its PDF destination, often called Save as PDF or Microsoft Print to PDF. Save the puzzle and its solution separately so the answer stays out of sight.
For a cleaner sheet: If the preview adds a date, URL, or page number, turn off the print window's headers and footers option. Check that the full grid and copyright line fit on the page.
For classroom or group copies: Print one puzzle and enough copies for your group. The black-and-white grid works with a monochrome printer. Keep one solution sheet for whoever is leading the activity.

Common Questions

Are all 100 easy Sudoku puzzles and answers free?

Yes. You can print or save any puzzle and its matching solution without an account, email address, or payment. Each numbered puzzle has its own Solution link.

Which puzzle should I start with?

If you are new to Sudoku, start with #001 and follow the worked example above, or choose any puzzle from #001-080. When those feel comfortable, try #081-100: A Little More Challenge. All 100 remain Easy, but the last group has fewer starting clues. Puzzle numbers within each group are not a strict difficulty ranking.

Are these suitable for children or older adults?

Choose by the person's experience and interest. A beginner who can recognize the numbers 1 through 9 can learn the rules with help, while an experienced solver may enjoy these as a relaxed warm-up. One large grid per page gives everyone more room to write. If teaching someone, work through a few squares together before handing over the pencil.

Can I download the whole collection as one PDF?

This collection is organized as individual puzzle and solution pages. Use the PDF option in the print window to save the particular puzzles you want, and keep their three-digit numbers in the filenames so the answers are easy to match.

May I copy or share these Sudoku puzzles?

Yes. You may print and share copies for home, classroom, church, club, workplace, care-home, or activity-group use. Keep the copyright line in place, and do not sell the puzzles. You may also include a puzzle in a newsletter or other publication with this credit: "© Memory-Improvement-Tips.com. Reprinted by Permission."
