Sudoku
« on: October 03, 2010, 06:14:59 pm »
Here's the progress on a Sudoku program that I'm working on.  It's about 10% complete.  I need to know three things:
a) Who would want this?  I want to make it, so regardless, it's getting made. :P
b) Does anyone know where there's about 50 Sudoku puzzles that I could copy and put in the game?
c) What should the Menu have in it?  I have a couple of ideas, but I want to know what you guys think. :)

Thanks! ;D

"Billions of Free Sudoku Puzzles" ... wow, sudoku's obviously got a lot of combos!

Not as many as the Rubik's Cube, of course ;)

yeah. and if you click the link to the "deluxe edition" or whatever they have 4x4, 6x6, 12x12, 16x16, and a couple variations of sudoku. but you have to download it.. and even then you only have a 60 minute trial until you have to pay money. i remember when i just started basic programming i wanted to make sudoku but didn't know how.

Wow, awesome! Back then, I tried to make a sudoku solver but eventually I quit because I lacked the programming skills needed for such a task. :P Maybe I should start it again someday...

1. MEEEEEEE!!!
2. See nemo's suggestion above :P
3. New, Save, Load, Restart, Quit

Looks nice. Unfortunately I'm not a fan of Sudoku, though, so I'm probably gonna pass on this one :(

Hopefully a lot of people will enjoy it :).

How many sudoku are going to be preloaded?  Do you think an on calc generator is possible?  Are you going to scramble the preloaded so that it is even more random?

:D

They will be 81 bytes each and I'm estimating 50 levels.

I think it's possible, but I am unsure on size or speed.  I doubt if I'll include one in this program, though.

I don't know how one would work.  If you have some pseudo-code, then it's a possibility. :)

okay, with some rowswapping and that little t thing we can do this in no time :D

Code: [Select]
   012345678

0  000111222
1  000111222
2  000111222
3  333444555
4  333444555
5  333444555
6  666777888
7  666777888
8  666777888
Alright so here is our sudoku board.  Can you see that if we swap column 012 with 345 we dont change the solvability of the puzzle?  In addition, we can swap and group of 3 columns (012, 345 or 678) with any of the others and still maintain solvability.  In adition, we can swap column 0 with column 1, 1 with 2, or 0 with 2.  In any group of 3 (012,345, or 678) we can swap any of the single columns without making the puzzle any more difficult of unsolvable.  We can then use the fancy t thing, flip the matrix, and do the same thing with all the rows.  And as a final note, you can rotate a sudoku as much as you want and it doesn't do anything :D.  So all we need is swapping rows and flipping! Both have fast and built in routines to do that for us :)

So it would look something like this:

Code: [Select]
For(G,0,1)

  For(F,1,5)
    Rand(0,2)*3->I
    Rand(0,2)*3->J  //that *isnt* I
    Swap(I,J)
    Swap(I+1,J+1)
    Swap(I+2,J+3)
  End
  For(R,0,2)
    For(G,1,5)
      Rand(0,2)->I
      Rand(0,2)->J //that *isnt* I
      Swap(R*3+I,R*3+J)
    End
  End

  FlipMatrix

End

For(F,0,Rand(0,3)
  FlipMatrix
End

Should all work but its all theoretical!  XD

OH!

I get it!  That's a very easy thing to do - I didn't realize I could do that.  I will certainly be implementing this!  Thanks Builderboy! ;D
