I just started a thread on this! Wow.

― Tom (Groke), Thursday, 12 May 2005 14:16 (twenty-one years ago)

it's gone now! ;)

I could swear I've seen something similar to this game before in puzzle magazines.

― teeny (teeny), Thursday, 12 May 2005 14:19 (twenty-one years ago)

The mods are more vigilant than in my day though.

Anyway I am suspicious of this fad, it looks like a logic problems sort of thing except without the comedy situations (Five housewives all bought different types of washing powder etc etc.) Also I do not immediately see a way of playing "Dirty Sudoku".

― Tom (Groke), Thursday, 12 May 2005 14:19 (twenty-one years ago)

wow, it sounds decidedly unfun.

― mark p (Mark P), Thursday, 12 May 2005 14:24 (twenty-one years ago)

I have confirmed with my mom, she has been playing this for decades in puzzle books.

it's ok. not bored of it yet. what i want to know is what kicked off the fad in the UK? it's not a new thing in the world, but it's gone from nowhere to ubiquity in weeks

― Gravel Puzzleworth (Gregory Henry), Thursday, 12 May 2005 15:11 (twenty-one years ago)

I'm intrigued that they say maths is not involved at all. I guess that it just looks maths-y because of the numbers.

― Japanese Giraffe (Japanese Giraffe), Thursday, 12 May 2005 15:19 (twenty-one years ago)

Among lots of other fun stuff, there's a great sudoku tutorial on this site:

http://www.nikoli.co.jp/en/

― Japanese Giraffe (Japanese Giraffe), Thursday, 12 May 2005 15:21 (twenty-one years ago)

This game was featured in GAMES magazine at least since the early 80s.

― gygax! (gygax!), Thursday, 12 May 2005 15:45 (twenty-one years ago)

the guardian one today is the first i've seen (in the guardian) and it's very sparse = hard. the independent's used to get harder during the week with monday's and tuesday's piss easy. i wrote a little something in javascript that'll solve the easy ones, didn't quite get the brute forcing of the harder puzzle sorted before i lost interest (recursion, ick!).

> Also I do not immediately see a way of playing "Dirty Sudoku".

just fill all the boxes with 6s and 9s.

― koogs (koogs), Thursday, 12 May 2005 16:00 (twenty-one years ago)

I had yesterday's Guardian one lying around and have just solved it, at least I think I have, this is the problem with sudoku, I really can't be arsed to actually check.

― Tom (Groke), Thursday, 12 May 2005 16:10 (twenty-one years ago)

That is the first one I have ever done, though. But it was quite fun!

― Tom (Groke), Thursday, 12 May 2005 16:13 (twenty-one years ago)

this doesn't look fun to me at all! i haven't actually tried one yet, though. the guardian's whole "ours are hand designed" thing seems really odd to me - isn't this exactly the kind of thing that computers should be good at designing?

― toby (tsg20), Saturday, 14 May 2005 06:32 (twenty-one years ago)

It's like a crossword with numbers and logic yeah? I fucking hate crosswords. I fucking hate number puzzles.

― Sick Mouthy (Nick Southall), Saturday, 14 May 2005 06:39 (twenty-one years ago)

"Forget the computerised versions spreading like fast-food joints in other newspapers. Pit your wits against the authors of the Guardian's unique Sudoku classic - the only version in the country with each puzzle hand-generated by the game's Japanese inventors."

When they started going on about them being "hand-crafted on the slopes of Mount Fuji", you've got to figure they're taking the piss.

Hadn't tried one of these before yesterday's Guardian, with one on every page of G2. Now I'm addicted to the bastards. And I don't even enjoy it.

― James Ball (James Ball), Saturday, 14 May 2005 16:45 (twenty-one years ago)

sat down on saturday night and did thursday's and saturday's guardian puzzles and they are a different kettle of fish to the (easier) independent ones i'd tried before. they took over an hour each whereas the indie ones (of which i'd only seen the easier start of week puzzles, they now have 3 graded puzzles every day) you can fill in as fast as you can write (almost). what struck me was how there was always a logical step, there was never any reason to resort to trail and error. learnt a couple of new tricks as well.

indie has a 16x16 puzzle on saturdays. hmmmm, hexadecimal...

― koogs (koogs), Monday, 16 May 2005 07:33 (twenty-one years ago)

Has anyone yet managed to perceive the "almost imperceptible wordplay" supposedly evident in the Grauniad ones?

(not that I would necessarily know as I finally gave up on the Guardian last week)

― Marcello Carlin (nostudium), Monday, 16 May 2005 07:37 (twenty-one years ago)

what struck me was how there was always a logical step, there was never any reason to resort to trail and error.

This is supposed to be the main benefit of hand-written sudoku over computer-generated ones.

I've been doing the Guardian ones, and I like them because there is that constant logical trail through them. You can stare at one for 10 minutes and not spot the way forward, before suddenly spotting a connection that lets a whole series of numbers fall into place.

The one thing I don't like about any of these sort of logic puzzles is the boring clearing-up you're left with towards the end - when you're left with lots of boxes or rows with 7 or 8 numbers filled in, and it's easy-but-boring to finish the thing off. Sudoku isn't as bad for this as some other sorts of logic puzzle though.

― caitlin (caitlin), Wednesday, 18 May 2005 20:03 (twenty-one years ago)

i find starting the damn things is the tedious bit, writing out all the possible combinations in each square. modified this yesterday to sort that out.

http://home.clara.co.uk/koogy/SoDorky.html

am thinking of making this completely dumb so it doesn't try and solve things for you - it often does too good a job. even though it's currently missing an obvious step - if a column only has one possible 3, for instance, it doesn't yet notice.

― koogs (koogs), Thursday, 19 May 2005 08:43 (twenty-one years ago)

Doesn't have the satisfaction of a good crossword, because you know that if you plug away at it for long enough you will always be able to finish: it's just a question of devoting the time, and the last maybe 25% is a matter of just entering the only possible numbers.

― bham, Thursday, 19 May 2005 10:03 (twenty-one years ago)

i find starting the damn things is the tedious bit, writing out all the possible combinations in each square

You have to do this? I don't bother making notes or anything; at the start I just scan through each digit and see if there are any definite places to start.

― caitlin (caitlin), Thursday, 19 May 2005 10:39 (twenty-one years ago)

it's called 'caching' 8) i get fed up of working everything out again and again (that said, making sure everything is up to date when you've got cascading solutions happening is tricky in itself)

someone pointed out yesterday that he didn't bother writing anything down but then he was doing the 'elementary' level one in the indie. i tried it last night and it took much longer.

― koogs (koogs), Thursday, 19 May 2005 11:13 (twenty-one years ago)

Oh, it probably does take me longer to do it that way overall.

― caitlin (caitlin), Thursday, 19 May 2005 11:14 (twenty-one years ago)

― Japanese Giraffe (Japanese Giraffe), Thursday, 19 May 2005 21:16 (twenty-one years ago)

made some changes last night so you can pass the initial game state in as an argument. hava also stripped out all the autofilling stuff and made viewing of possible values optional so it's more like the pencil and paper experience (that said, the ddlb still only lists possible values so...):

one from the times

have about 7 or 8 more of varying difficulty just lying around the office so i'll post those later

(oh, the above html will run locally just fine, it doesn't use the server to hold game state or anything, it's all javascript generated on the fly. as a consequence the back button doesn't undo as you'd expect.)

― koogs (koogs), Friday, 20 May 2005 07:40 (twenty-one years ago)

Another way in which it is inferior to crosswords (I discovered yesterday): if you discover about two thirds of the way through that you have made a mistake (ie at some point put a number in the wrong square), the whole thing is f*cked - you have to abandon it or start again at the beginning - very annoying

― joseph (joseph), Monday, 20 June 2005 22:17 (twenty years ago)

this was in the guardian couple of saturdays ago and i can't solve it without resorting to trial and error (which, i'm told, you should never need). anyone?

(this is as close as i get)

((row 1 column 0 is a 5 in the full solution))

ailsa otm about writing something to solve them - i ended up taking all that out. new version will provide hints but won't autofill or brute force the solutions.

toby's link was interesting but i'm more interested in how few squares you have to define, and which ones, in order for it to be solvable.

― koogs (koogs), Tuesday, 21 June 2005 07:50 (twenty years ago)

Oh god, apparently everyone in my new office are really into these. I said I'd write some code to solve them for me.

This might be tricky, there are a lot of things that are a bit subtle. For example in the one for last Friday:

http://image.guardian.co.uk/sys-files/Guardian/documents/2005/06/17/GdnSudoku035_050617_3.pdf

Something like Koogs' program will quickly place a 7 in the seventh row, and then one in the ninth column. After that, it's easy to 'see' that in the sixth column, the seventh eighth and ninth numbers will be 1, 8 and 9 in some combination, and so the fourth fifth and sixth will be 2, 5 and 7 (and so the fourth one must be 2), but it's a bit tricky to program.

― Andrew Farrell (afarrell), Tuesday, 21 June 2005 17:03 (twenty years ago)

Koogs: consider the 5's, first in the ninth row, then in the second column.

― Andrew Farrell (afarrell), Tuesday, 21 June 2005 17:38 (twenty years ago)

(Obviously, I actually mean "there is at least one thing that's a bit subtle")

― Andrew Farrell (afarrell), Tuesday, 21 June 2005 17:38 (twenty years ago)

> Koogs: consider the 5's, first in the ninth row, then in the second column.

gotcha. 1 of 9,1 or 9,3 must be a 5. which means 8,2 must be a 1. etc.

first time i've seen it be that subtle (and the puzzle was only marked a medium). sometimes for a medium there's the case where the only possible values for a pair of squares are on the same line meaning nothing else on that line can take that value but often you don't even need that and the above is a step further. (and, like you say, v hard to program. the code to check for only one possible position remaining for a value in a single row / column / square is fiddly enough - the hint thing in SoDorky3.html i wrote on monday night is about half the code again and triple nested loops usig values as indexes into other arrays)

― Andrew Farrell (afarrell), Wednesday, 22 June 2005 08:11 (twenty years ago)

i enjoy these, but enthusiasm will prob'ly wear off after a while.

i was intrigued by someone saying upthread that it gets easy-but-boring at the end "clearing up". i know what you mean, and there's an element of that, but i also sometimes get stuck right at the end because there are two out of nine numbers still to fit in, in four or five boxes. And you've got an either/or situation in each box, with both options looking as if they will work and no obvious logical solution. anyone else found this?

― zebedee (zebedee), Wednesday, 22 June 2005 08:30 (twenty years ago)

this should never happen. the 'rules' i read somewhere say that there's never any need for trial and error, everything is logical, either only one value will be possible for a square or only one square will be possible for a value.

― koogs (koogs), Wednesday, 22 June 2005 08:34 (twenty years ago)

Yeah, I picked up one that I fucked up yesterday, and went over it with a different color pen, and the main difference was just switching 7 and 9 everywhere. But there's usually a solution if you look.

― Andrew Farrell (afarrell), Wednesday, 22 June 2005 08:35 (twenty years ago)

xpost - obviously you can get an impossible problem: either one where the stuff that's specified matches more than one solution, or enough to match one solution + a contradictory value.

― Andrew Farrell (afarrell), Wednesday, 22 June 2005 08:39 (twenty years ago)

I like that I'm making out that I'm some battle-scarred veteran: I picked up my first one yesterday and I've done maybe half a dozen.

― Andrew Farrell (afarrell), Wednesday, 22 June 2005 08:41 (twenty years ago)

I think it depends how good the compiler is. I've seen one or examples I'm convinced can't be completed logically (ie without guessing or trial and error). The Times claim that theirs (unlike some others) can all be completed logically and so far that has been true of the ones I've done. The Samurai on Saturday was a bastard, though, allegedly easier than the previous week but not for me it wasn't.

Classic just now but probably dud in the not too distant.

Your best bet is to use that method with the middle left grid

― Orbit (Orbit), Saturday, 2 July 2005 18:25 (twenty years ago)

It has to be a "1" in the left square of the middle left grid, which means a "7" goes in other blank box

― Orbit (Orbit), Saturday, 2 July 2005 19:40 (twenty years ago)

What a strange article. Why demonstrate a method when there's a much simpler way of getting the same answer (there's no other number that could fit in that spot).

Anyway, I don't quite follow how you're applying it there.

― Andrew Farrell (afarrell), Sunday, 3 July 2005 01:25 (twenty years ago)

neither do I. What I do have so far is that the top middle square of the top right box must be a 9, since it can't be anything else. By same reasoning, the middle number in the left hand column of the bottom middle box must be an 8.

Once you've placed them, you should be able to work out the contents of a few other things. I'm a wee bit further on than that, but I still can't conclusively show which way round the 1 and the 7 go in that middle left box.

Sudoku boards---I just want to fill them in with random numbers.

My 7th grade algebra teacher gave us "number crossword puzzles" for extra credit. You'd solve equations and fill in the xword w/the sums. I quickly realized she didn't actually check the answers, so I'd spend a minute or two each day filling in the several-hour xword w/any old integers. Easy extra credit. Consequently, I can't even think when I see a sudoku puzzle. I go back to 7th grade brain and want to write "3 7 4 1 6 8" etc., at random.

I saw my hometown's paper at the library and their sudoku puzzle has a clip art bamboo border and Chinese restaurant menu-style typeface for even the instructions. I thought it was humiliating. The paper had an article once where they interviewed a diplomat from Japan, and all they asked him about was "how is to eat squid?" Wotta town.

i played a sudoku board game last weekend. it was kind of odd. you fill in numbers with different colored dry erase markers and basically get as many as you can in the 30 seconds (one of those hourglass shaped sand timer things) and then pass on to the next person and at the end see who filled in the most numbers. it's sort of fun, but gets REALLY fucked up if someone puts a wrong number in.
