My new Sudoku variant

Postby jsmith » Sat Apr 27, 2013 6:34 pm

Hi everyone,
A few years ago I had an idea for a sudoku variant, but did nothing about it. It's based on an 8x8 board with split cells making an unusual 10x10 arrangement that you fill with the digits 0-9. Anyway, last year I coded it up [I'm a software engineer in my day job], put in on the web and did nothing about it.

It's available at http://sudo10.com and it would be great if someone could let me know what they think. In particular, I'd love honest feedback about things like:
  • Is it fun to play?
  • Is it original, or have you seen something similar before?
  • Is it too easy or too hard?
  • Can you think of any ways to improve it?

It's got a couple of difficulty levels, and you may find it more enjoyable if you switch to the hard difficulty.

I'm not sure why nobody replied or commented to this yet (Probably due to the waning interest in sudoku nowadays!!)

This is a lovely idea & a lovely variant ... Well done

The triangles will make it difficult to type graphically or transport digitally for electronic solvers.

Possibly because the website gives you nothing but a blank screen with the message "your bowser" [ sic ] "is not supported, please upgrade it". I'd like to look at it, but I can't.

Yes Bill I can confirm what you're saying when using IE8. I must have viewed it originally on Safari!!!

Good point, I should try and support that browser. Or Bowser!

I've updated it to work in Internet Explorer 8. I hope that lets you try it, Bill. It still doesn't work in older browsers, so I have some more work to do.

It works now, but I get a warning message that a script is slowing down my computer, and if I let it continue, it might bring my computer to a screeching halt. It also let me opt out of that script, which I did, and then the main puzzle came on.

Obviously that puzzle has at least 10-factorial solutions, if it has one. That doesn't necessarily make it easy, though. I'll try it later.

Bill, stopping the script stopped the board getting created properly. You should have seen a partially filled in board with one solution, not 10! The website isn't important anyway, what I really want to know is what you think of the variant. Below is an example board - I hope you can get a feel for it from that

Yeh, that's more like it. I'm glad you're better at creating puzzles than you are at designing websites. :)

I'll give it a try soon.

Motris has recently been posting similar puzzles, see:

http://www.gmpuzzles.com/blog/

He has an extra constraint that the "fractions" must be proper i.e. the upper number must be less than the lower one.

Wow, there are lots of interesting variants there. Were you referring to the tight-fit sudokus? http://www.gmpuzzles.com/blog/category/sudoku/tight-fit-sudoku/.

For my boards, the restriction that a smaller number is above a larger 't make as much sense as the point of the diagonals is to split the board into separate regions much like the sudoku board.

That the one I meant and I see your point about the constraint.
