Do you Sudoku?

My 17 year old son turned me onto this.

Warning: it can be addictive.

Su Doku is clearly a denial of service attack on the collective intelligence of the human race.

I recommand you cure yourself by writing a program to solve them for you. Its pretty easy, I did it in less time than it took my wife to solve the puzzle I then solved with it.

My wife discovered Sudoku (well if you can call it discovered when every square inch of the UK is covered with them (1) ) and now our life seems to revolve around them.  She’s been busy writing a solver for the past few days, and she’s pretty much there - I dread to think what’ll be next. I can still sort of remember what she looks like ...

If you have any sort of programming or logic based background - stay well clear, this will keep you occupied longer than the instructions on a bottle of shampoo(2).

1 A slight exaggeration, but if you don’t find at least 2 in any daily paper something is seriously wrong.
2 Lather, Rinse, Repeat.

Aha, Su-doku is great. I used to do (sure, addicted) it in my high school days — it’d taken me to Todai ([link]) — :-)

yeah, it’s been pretty big here in the UK for the past year or so. Whilst it’s trivial to write a program to solve and generate puzzles, I think what’s tricky is having generated a puzzle, getting a realistic idea of how difficult it is for a human to solve. Krazydad has generated loads of puzzles as PDF files, here

There’s a good online sudoku site at Fiendish Sudoku.

It has new puzzles every day at five difficulty levels, and an archive of hundreds of puzzles. All the puzzle designs are hand-made, not random computer generated.

Fiendish Sudoku can provide hints and step-by-step solutions. It has a choice of grid sizes and several printing options.

I’ve just launched a samurai sudoku site at Samurai Sudoku.

It’s the first free samuari sudoku solver on the web, as far as I’m aware. I post a new samurai puzzle each day. You can either use the online solving grid and take advantage of pencilmarks, hints and step-by-step solutions, or you can print the puzzle out at one of several grid sizes.
