Well, it's writing stuff in the right places now, it just happens to be writing the wrong stuff  |

For some reason it thinks it can overwrite cells which have already been filled  |

*fixes some code to prepare for introduction of the backtracking stuff*
[edit]
And the overwriting stuff is fixed now. If you check for possible values of filled cells, it actually is possible to conclude that you can overwrite it with a new value

Added some non-backtracking stuff, but it decided to cheat when the puzzle was almost complete and put the same number twice in the same grid |

Bah, got down to the two last spaces, at which point it bailed because it needed to backtrack |

Well, that bit works, but there's a bug in the bit next to it |

OK, it should work this time
And luckily it wasn't an interpreter bug |

c0de! I'm impressed.
I haven't run it myself, I trust it works.
How many have you tested it on? |

Just one
You'll need a funge-98 interpreter (*cough*) to run it. |

Today's puzzle must be easier - it solves that one without backtracking |

I suggest you look at Wikipedia:Sodoku
Not only does this have a set of pointers to variants, it also describes some of the more interesting logical possibilities (see for example "unmatched candidate deletion").
And you could add your solver to the list at the bottom, for eternal glory. But I suggest you test it a bit more first. |

Oooh, this is my 6999th post. I'd better have something important to say for my next one 
Not only does this have a set of pointers to variants So how come I can't find any of them?

You doubt the accuracy of my code? Well, I manually solved the one you posted a picture of, and got the same result. But in my experience just because a program works for one input doesn't guarantee that it will work for everything.

Maybe they arn't available on the internet
Actually, I've got a subtle plan for a combined puzzle. Might try and reify an example later.

Well that's stupid then! How are we meant to do stuff it it isn't available on the Internet?

Pfft, someone in Qercus has written one in BASIC. And it doesn't even support different sizes of grid!

Metoo.
But I haven't seen anything inside yet, apart from glimpsing its sodoku solver. |

Soduku cover?
Because clearly there hasn't been saturation coverage of that everywhere else. FFS. If I want to read a RISC OS mag, I want something slightly different than mainstream stuff. |
