Hello Sudoku lovers!

This post is here to receive feedback, suggestions, bugs (impossible! eheh)

  1. Elbert Ford Says:

    There seems to be no way to enter a correct number if you happen to enter another one in error.


  2. Heracleum Says:

    You can freely input any value in any cell, obviously not on given values: you can change the value on cells at any time and no matter if you enter a wrong value on a cell, even if you already have that value on the same box / row / column. So I could rather understand if one complains in the “opposite way”, something like: “hey, there is no check on same/incorrect values in the grid!” :)
    The only check on correct values is done at the END of the game, when the grid is full, otherwise all inputs on an incomplete grid is considered “temporary” and not to check.

  4. NR Says:

    Is there any way to make the timer pause. I like to know how long it takes me sometimes but (for the bigger, longer puzzles this is particularly a problem) I can’t leave the puzzle for a couple of minutes if I want to.

  5. Heracleum Says:

    Hi NR, of course you can Pause the game: just click on the Timer itself, it will freeze time and game grid will be hidden, revealing the background image, in case you’re interested in viewing it as well eheh.
    Here is the how to play sudoku page in case you need to know about other game features (i.e. using the mouse-wheel to select values or simply hide the background…).

  6. Sudoku Maniac Says:

    is it possible to stop the timer for a while ?

  7. sarah Says:

    omg i love these games there HILARIOUS.. totally addicted to them, i recommend them to EVERYBODY, but there seems to be a slight error in the makings ;)l

  8. Siobhain Says:

    there appears to be a malfunction on the 25×25 games with the keys. Not with all, but A - I all appear as different letters, making it impossible to play the game! Can you fix?

  9. Heracleum Says:

    :O !!!!
    You’re totally right! Oh my… yes A-I are replaced with Q-Y :(
    what a stupid bug!
    While in 16×16 it’s all right.
    Thank you for the very accurate bug report! I really appreciate, I’ll let you know about the fix.

  10. Adele Says:

    Please use hexadecimal for 16×16 puzzles.

  11. Chris Says:

    I can do the Hard 9×9 quite quickly. The Easy setting on 25×25 is too easy to be interesting to me. But the Hard 25×25 is something that I can never finish. Could you make it a little bit easier? Is this something other solvers think? The Independent in Britain publishes a 25×25 each week which takes about 2 hrs to solve - that level I think is about right for an online version.

  12. Robyn Says:

    I like this website, but I refuse to use it on days that there are pictures of somewhat naked women in the advertisements….

  13. Howard Says:

    Hi, Hera, ’sme again. Never mind what I said about Sudoku not loading. My stupid PC’s Java was requesting permission to load (!) and I didn’t notice the request. (Damn Norton Security.)

  14. Heracleum Says:

    Oh yes Howard, I think it requested your confirmation to load the pictures (external to Java applet). Uhm I think it’s also time to change the background images set ;)

  15. Nee Says:

    It would be great if there was a way to save your progress and then be able to return to the puzzle later. Some of these big puzzles can take me a really long time to do, and it would be nice if I could continue later, or save my progress before my computer freezes, etc.

  16. Barbara Rosen Says:

    Love your site and puzzles.

    I do the huge (25×25)-hard all the time, cutting and pasting into word, then cropping and resizing and printing. My comment/suggestion is that if you could put the puzzle date in the background, next to the “Given cells” or next to the version at the bottom, that would save the user the task of putting the date on it themselves. When you prepare more than 1, as I do before traveling, you need the date to keep them straight.


  17. Heracleum Says:

    Nee and Barbara,
    those are both excellent suggestions.
    So, providing a “printable version” and a “save” functions.
    Thanks to both.

  18. Patrick Says:

    This is a good website for sudoku! My only thing is, is there a way to save what I’ve done so far, that way I don’t have to do a puzzle all at once? 16×16 hard are good puzzles, but they’re hard for me to do all in one setting. Thanks.

  19. nancy Says:

    I’ve pretty much left this site because the only puzzles I like are the large ones, but I can’t do them in one sitting. On April 23, 2010, Heracleum said that a “save” function had been provided, but I can’t for the life of me figure out where or how. The one place that seems like a possibility says: “Copy this link for an absolute reference to this Puzzle”, but all that does is bring up the puzzle, not any entries I’ve made. Any help? It’s been a while since Patrick’s entry…is the site still being monitored?

    However this turns out, thank you for providing these for us! It IS appreciated.

  20. Heracleum Says:

    I’m sorry! On that comment I meant that those were legit features to implement, especially after all the time that passed since then… actually, the big problem is that it is about 5 years I don’t develop in Java anymore, none of the tools installed but even worse I’m afraid I’ve lost the original source files :/ (that is a shame since it took me several months to build the puzzle creator engine). I’ll do my best to search for it!

  21. nancy Says:

    Not to worry. 8)

    I’m sure you have many things to do in your life and it sounds like implementing a “save” function would be pretty time consuming.

    Thank you for responding!

  22. Peter Paul Says:

    Is it possible that if you click on, say, a letter “B” that all other letter “B”s are highlighted?

  23. Gordon Stewart Says:

    My solution agrees with the “SOLUTION” but when I finished, instead of CORRECT it said WRONG.
    What happened? How do I proceed?

  24. cabiria11 Says:

    Perché non riesco ad aprire il sudoku? Mi dice che la pagina è bloccata perché il sito non è sicuro. Ieri ho fatto un aggiornamento Java, che sia quello?

  25. dawn Says:

    The latest Java update is apparently blocking my ability to play your Sudoku - it says your application is unsigned or untrusted. Help! I am addicted to your game!

  26. Heracleum Says:

    To safely run the Sudoku applet I suggest to add the URL(s): (for Italian version)
    in the Exception Site List in the Security tab of Java Panel.
    See official instructions and FAQ here:
