Online Sudoku

Online Sudoku is a javascript version of the popular japanese number game sudoku. This can be used to play sudoku online. Sudoku is a mind game and a puzzle that you solve with reasoning and logic. Fill in the grid with digits in such a manner that every row, every column and every 3x3 box accommodates the digits 1-9, without repeating any. For more info about how the game is played, please visit the Sudoku page in Wikipedia.

How about a leaderboard? and an extreme level? that would be awesome.

I don't know how to put several small numbers in one cell until I know which one is right. How do I do that?

Anonymous at 09 Mar, 2007 10:18

simply type all numbers in the one cell.

I've seen these puzzles in the grocery stores and even saw students attacking them in the classrooms, but I never tried to figure one out for myself. Thanks for the "teaching" instructions. I've just completed my first one ever and I'm so happy to have found a daily brain teaser.

I picked up the pen (cause i didnt know what that meant), and dropped it immmediately (when i figured it out). but now everytime i click it still fills it in with whatever i typed last - annyoing

other than that its great - and even better my company doesnt block the website!

Binny V A at 23 Mar, 2007 01:26

yay for css naked day

The_Missing_Link at 12 Apr, 2007 11:39

need better presentation. would be helpful if grids are marked instead of blank small squares. otherwise good site. difficulty levels need be more complex.

Binny V A at 13 Apr, 2007 06:52

Presentation is one of the strong points of this app - you can change the style using the 'style' dropdown in the right side toolbox. Choose the 'Paper' style. I am sure you will like it.

Averaging around 6 minutes for Hard Puzzle

Anonymous at 16 Jun, 2007 08:37

Crap.. I'm around 10:30 for the default ones.. which I assume is easy. Just learned how to play last night so I'll get faster hopefully. Actually tried to learn this game 6 months ago and believe it or not was trying to add all the numbers to equal 45 on each side. Needless to say I thought the games sucked hard. Now I love it.. it's so addicting!

Anonymous at 09 Oct, 2007 03:43

They will all add to 45 if you do it right!

Snorre at 31 Aug, 2007 12:55

Hi.

I used this script on my company's page: www.toyentrykk.no/?side=sudoku

I translated it to Norwegian, and I modified it so it has five different levels of difficulty; Kiddie-version, Very easy, Easy, Medium and Hard. I also modified it so that the users have to choose level of difficulty before the script loads.

Thank you very much for the great script! :D

Anonymous at 20 Mar, 2008 09:18

I have encountered a few puzzles with multiple solutions. For the most part each puzzle generated has a single solution, but on occasions it breaks this. You should probably revise the method the program checks for this to make sure it doesn’t break the "rules" of Sudoku. However, it’s excellent otherwise.

Anonymous at 26 Mar, 2008 07:26

Thanx a lot... very interesting and addictive too...

Anonymous at 07 Apr, 2008 04:41

when I press green or orange .. it runs over the numbers.. hence it is difficult to read the puzzle..

Sudoku Maniac at 07 Apr, 2008 04:43

It will be great if the puzzle changes to hard when I change the difficult level automatically..

Anonymous at 19 Apr, 2008 02:01

Thanks for the great script. Did some very minor cosmetic changes and really enjoy it. We'll see how it works out.

My fastest time in the category easy is 02:13. I have started off with the normal lately and I have recorded a time of 04:20. This is a great game and I am looking forward to improve my time with more and more practice. This game helps me relax completely.

The hard level is too easy. Would appreciate even harder puzzles.

Susan G. at 12 Oct, 2009 07:43

I discovered this website when we were on vacation in Hawaii, I used to do the Sudoku in the paper there everyday. They had an online version of the paper which I would go to when I got home, and the Sudoku puzzle part of the paper led me here. I am on a Mac computer. I use a (shift, apple, 4) command and outline the paper version of the puzzle, and print it, it fills up the whole 8 1/2 by 11 piece of paper. I do the puzzle by hand on the paper, save the puzzle here on the computer, come back later, plug in my answers and see if I got it right. This is just my little idiosyncratic way of doing it, but I really love it. I am super busy, and I will pick up my piece of paper and put it down again, maybe for days, before I finish it, but my saved puzzle is still there until I am done. this way I can do it at my leisure. I really appreciate you guys. Thanks for the fun.

I replaced the numbers with pictures. This makes a nice game for people with discalculi. Without the numbers it is (clear) this is no math but a logic game. Folow this shortened link to see txf.nl/8 [ txf.nl/8 ]

bdimag at 17 Feb, 2010 02:51

me again,
put a few numbers in a cell and it switches to the smaller red font... when you reset or start new puzzle that cell keeps the formatting.

Anonymous at 22 Feb, 2010 08:16

Great site, I spend too much time here. But it's not a Japanese game - it was invented by an American named Howard Garns, who called it Number Place. The Japanese just made it popular.
