Re: Hello

I subscribed to Tough Puzzles for a year when I was 14. Couldn't solve most of the puzzles, but I enjoyed seeing a variety of new puzzle types. In particular, I think it was my first introduction to Cross Sums (similar to Kakuro). Since Nick asked, I'll chime in to say my favourite puzzles were gene...

Re: Results: 2020 UK Puzzle Championship

Congrats James. Bad luck Freddie, though I've now doubt you'll win plenty of future competitions at this rate. Thanks as always to Liane and all the other organisers/ setters. And I did smile when I read the instruction booklet and saw 'You're Missing a Six', always nice to see clever inventions bas...

Fwiw, I wouldn't describe this discussion as 'controversy', so I don't think you have anything to be concerned about, Tom.

Re: WPF Puzzle GP 2020

Congrats on a really good result Freddie! For my part, I made a small error on the yajilin that I didn't catch- it was an actual solving error rather than a answer string error, which is perhaps slightly less annoying (but more worrying), but still a big chunk of points to throw away. I also solved ...

Re: WPF Puzzle GP 2020

I'm not a fan of number sequence puzzles in general, but this one was nowhere near as bad as the one from last year's Mind Sports Olympiad that was posted in another thread at the time. The difference between successful numbers is 22, 42, 68... The difference between *those* numbers is 20, 26, 32......

Re: WPF Sudoku GP 2020

I felt like I solved more puzzles than I did which is an odd feeling. But anyway, those that I did solve were (mostly ;-) ) nice, particularly the diagonals.

Re: 20th 24HPC in Budapest

As Tom says, I plan to attend, but haven't sorted out exact schedules yet (I haven't checked flight prices because Tom's scared me too much). But I'm definitely planning to do something puzzle-y on the Friday if people are around. :-)

Re: Puzzles at the Mind Sports Olympiad in London on Sunday

Congrats Rodders. I could've stared at that sequence all day and not got the answer (I already did spend about as long on it as I spent on all the other puzzles combined!) so as Tom said, solving it makes you a worthy winner. That's one reason why reusing puzzles is clearly far from ideal- I'd far r...

Re: WPF Puzzle GP

I spent probably over half an hour getting most-but-not-all of the massive pointer at the end. I subsequently broke the slalom as well, plus both snakes (although by that stage I was largely guessing). Of the puzzles you mentioned, I did solve the Fibonacci Doppleblock and the Unequal Slitherlink- b...

Just to add balance, I actually hated it! But that's likely down to me, rather than the puzzles.

Is point 1 true? I can't remember enough from my uni days frustratingly!
Can't find flaw in points 2-4 though.

Re: Figure sum sudoku [WPF sudoku GP 2017]

I don't like that definition due primarily to the use of the world 'primarily'. Similar to the way Fred has demonstrated on other types, it would be possible to create one of these puzzles where the structure placement constraint is used trivially, making that particular puzzle example a 'primarily'...

Re: Puzzle decorations

The top one is a classic sudoku. The bottom two are not, although they are obviously very close. (One difference is that the top example works just as well with the numbers replaced by unordered symbols, whereas the others don't). I think part of the reason in my head that it's not an analogous situ...

Re: Burodoku [new example]

One of the most interesting factors (to me) is that you could easily make a variation of this with some numbers missing (and possibly some more bold separations). Then you could make another variant with even more gaps and barriers. And so on, step by step, getting closer and closer to a traditional...

Re: Wrong Puzzles? [WSC 2011]

What would you say if I propose to you a slightly different thing, integrating some world "puzzle X" championships (because that's the good idea of your proposal): Monday-Tuesday: WSC - competition containing only sudoku as defined by the commitee. Thursday-Saturday: WPC, with the specification tha...

Re: Wrong Puzzles? [WSC 2011]

OK so I guess I should've foreseen that shortening the WSC so much would not be too popular amongst some groups of people (note that I didn't suggest killing the WSC altogether, my schedule still has a World Sudoku Championship in). However, I stand by my point that, in the puzzle community, there a...

To be fair, I did say I haven't thought out the details thoroughly. However, I am very much still in the camp that...

Re: Wrong Puzzles? [WSC 2011]

As the only person to vote that this is fair game for a sudoku competition, allow me to put forward my thoughts. Clearly, it's not a sudoku puzzle, or even a variant. It's a sudoku-related puzzle. I feel that all remotely sudoku-related puzzles should be allowed in the WSC. Conversations on other th...
