Su Doku

Here’s an massively evil game for you to play: Su Doku

If you’ve not played it yet then prepare to lose a lot of time…

It’s got very simple rules:

Each row must have the numbers from 1 to 9 in it

Each column must have the numbers from 1 to 9 in it

Each of the nine 3×3 boxes must have the numbers from 1 to 9 in them

… And that’s it.

Just click on the sample problems to have a go. If you’re new then I strongly suggest the ‘easy’ ones!

(You’ll need Java enabled for the games to run, but if you’re techy enough to know about that then you’ll probably be ready for that anyway.)

  1. I bought a book of them on Friday. Guess what I did for the ~entire weekend~ (except for the small portion of it which was spent at the beer festival)

  2. I did one a few weeks ago (in my last Maths lesson in fact). Would have done more, were it not for having my time taken up by A-levels. I’ll probably wind up doing them all summer though.

  4. 🙂 They are great fun aren’t they? Number puzzles shouldn’t be so addictive!

    LGGSaRaH, ‘glad you like my stuff, but I lost track of what you were trying to say towards the end of that post, maybe include some more of the letters in future: it makes it a lot more readable! I like hearing people’s comments, so it’s frustrating when the language has been abbreviated to the point where the meaning becomes lost. Thanks!

  5. Wow… I spent far more time than could be considered healthy finishing every puzzle on that page. Thanks for something to do at 3 in the morning!
