Re: World Puzzle Championships 2010 :D (Team Diary)

Anyway, the Old Town was completely destroyed - but they've rebuilt the whole area using original blueprints and the guide expressed extreme pride for her city about this which I found remarkable - I would compare the situation to Coventry which was similarly bombed, rebuilt, and is now treated in ...

Ditto, especially Nick Baxter and the rest of the Americans! With Thomas and Palmer (not to mention Hideaki) all competing, the rest of us might have a chance on nikoli.com :)

Re: World Puzzle Championships 2010 :D

George is a bit of a hero - we frequently ended up sharing a dinner table with him and the Chinese competitors in Philadelphia.

I shall try and pump my contacts for regular updates - probably best to keep focussed on the competition for now!

Re: 20/10 Decathlon

Aargh, you just pipped me. Congrats David, excellent score. Completely agree with the Mutant Skeleton and Masyu being the hardest - made some headway with the Masyu, just needs a bit of fiddling, but it's not intuitive at all. I did find the Skyscaper mutant easier than the hard one, and ditto the ...

Re: 20/10 Decathlon

Well I didn't buck the trend - however the LMI thread suggests that they are showing a bit of leniency. In this case it'll boost me from a provisional 600 to 750!

Re: 20/10 Decathlon

He certainly seems to be a big fan of this decathlon idea to find the best all-round puzzler. I remember a while back when I was in the habit of winding him up a little playing devil's advocate on his blog that he thought something like the decathlon was the best way to find the best athlete.

Re: LMI October Puzzle Test 1 - Nikoli Selection

Gareth - the first shaded squares I intend to be shaded are in the top left box - I'm fairly impressed you've got the second four-room down solved without to be honest. Here's my model solution: The top left is immediately forced, by the logic above: a.png Which ever way the second 2x2 subroom goes,...

Re: Bulgarian Puzzle Championships 2010

I fudged my way through some of the ones I thought I might be able to identify the rules of last night (not against the clock) - I had these printed out without any reference to Ronald's translation here. Some were fairly gentle I thought, eg the ABCD, the snail sudoku thing, differing neighbours an...

Re: LMI October Puzzle Test 1 - Nikoli Selection

Gareth - there was definitely logic to the heyawake. The main technique came twice with the 2x5 room in the top and bottom left corners. (And here I'm assuming with the bottom left room you get to the bit where the top row of the room is confirmed to be empty). At first it seems there are lots of wa...

Re: Nurikabe setting

Well - as I discovered to my peril with the LMI thing - you have to be a bit careful at the end to make sure that everything connects up, but generally you should be fine with set as you solve. Also there are plenty of nikoli nurikabe that aren't necessarily symmetric. I don't think that many of the...

Re: Nurikabe setting

I really enjoy setting nurikabe - I do it really intuitively, almost as if I was solving the puzzle whislt setting it. I basically throw in some initial clues, see what the implications for shading in squares is, and then go on from there adding new clues. You can then iterate this entirely linearly...

Nice to see some new names under the UK banner! Tom, well done on your first contest! I hope you aren't too disheartened by the errors - pass the buck on to your test solvers! Disappointed, but not disheartened :) The main thing from my point of view actually was messing up the heyawake. Modulo the...

Re: LMI October Puzzle Test 1 - Nikoli Selection

So I'm in a very conservative mood - I'm not going to post this at LMI until it's been confirmed that this is indeed error free - but here is the heyawake and the answer. I believe this is good - although I thought that about the first one too :roll:

Re: LMI October Puzzle Test 1 - Nikoli Selection

Naturally I'm a little disappointed with the way things have turned out, but I'm currently trying to fix the marathon heyawake. The nurikabe error was entirely stupid, and I guess I just can't make numberlink!

Glad everything else was fun though :)

Re: LMI October Puzzle Test 1 - Nikoli Selection

Yeah, this ought to be a good one ;) The marathon ones are there because I foresee I great difference in solving speeds for this one, and having people sat twiddling there thumbs (albeit with huge amounts of bonus points) seems a little pointless. It also acts as a nice bonus for your average solver...
