Printable Sudoku Puzzles (Deluxe Version)

Generate unlimited free Sudoku puzzles with varying degrees of difficulty!

Sudoku is a great activity to sharpen the mind. The object of Sudoku is to fill in the empty spaces of a 9x9 grid with numbers 1-9 in such a manner that every row, every column and every 3x3 box contains all numbers 1 through 9. It's fun and challenging for all ages. We also have 4x4 Sudoku for younger kids and 16x16 (Hexadoku) Sudoku for the enthusiast who wants a real challenge!

Printable Sudoku Puzzles (Deluxe Version)

Choose from a large single puzzle, 4 medium or 9 small puzzles per page. You can also choose your difficulty and page title. After printing the puzzle(s), simply close the window and generate and print the KEY for that Sudoku.

Fun Addition: Our printed puzzles are highly customizable and can also be printed with 'candidates' (i.e. available numbers for each cell) and we also compile a list of the strategies that it takes to solve each Sudoku Puzzle that you can add to each puzzle.

COMMON CONCERNS/QUESTIONS: (from the box below - keep comments coming)
1. Q: Regenerate multiple pages, same difficulty? A: Just choose difficulty level for each puzzle, create the puzzle(s) - it opens in a new window. Print these puzzles. Show Key, Print the Key. Click "Regenrate Puzzles" Button to get another page of puzzles.
2. Q: I like the size of the old ones better. A: EVERYTING is 100% adjustable. The left menu has a ton of options, make the puzzles bigger/smaller, change the font size, show cadidates, colors, thicker lines for poor vision, thinner lines to save ink. Show the exact difficulty score, Show the strategies required to solve each puzzle (more info on this coming soon), Play around with all of the options/buttons/sliders in the blue menu to see how you can customize your puzzles.
3. Q: I like how I used to be able to print 4 puzzles, please add that back. A: You still can print 4 puzzles - choose "4 Puzzles" in the options - it's in there. All 4 (even up to 9) WILL fit onto 1 page. If yours is printing to 2 pages (then your margins are bigger), just adjust the cells to be a tiny bit smaller (Grid Colors and Sizes > Puzzle Cell Size - slide it left). Lot of comments about this, so I am addressing it - even though the option is definitely there.
4. Q: Why the change? It is slower and more cumbersome. A: SEVERAL reasons:

  1. MOST IMPORTANT: The old puzzles were not "real sudoku" puzzles. Real puzzles have one solution - the old one is faster because we didn't test for number of solutions (or actual difficulty) for each puzzle. Like most Sudoku found on the internet, we simply created a completed puzzle grid, then removed numbers - choosing a harder difficulty just removed more numbers from the grid, but in many cases this made a puzzle EASIER because at a point it starts having more then one number that could go into the squares. Some of the old puzzles had hundreds of solutions. Counterintuitive, but true. We now solve each puzzle before sending it to analize the strategies required to solve it, assign the appropriate difficulty, and ensure that the number of solutions is "1" (or close to 1). These new puzzles are better in every way, except that they may take a couple of seconds to do all that stuff (Solving/Analyzing, etc.). But for those who don't care to wait the extra time for 'real Sudoku', the old Sudoku is still here.
  2. We also added different dimensions; smaller (and fun fonts and images and colors) for early learners (4x4) and bigger for more advanced users (16x16). More non-analyzed sizes coming soon. By request.
  3. We also added options to reduce the amount of ink used when printing (or you can increase it for poor vision). By Request.
  4. We also added a playable version so you don't have to print them - soon it will be playable on your phone or tablet. By Request
