Re: Divisions A and B 2020-2021
Crikey, that combined table is interesting. If Freddie and Sam had been in the same division, their combined impact has a huge impact on Friday's scores (enough to move Adam above Tom and Matthew, for example- incredibly, by just a single point!). I think that definitely argues for a slight alterati...

Re: Divisions A and B 2020-2021
I should have completed through to today (which I think was the last one), sorry for getting a little behind. I've enjoyed the way you've set this round up Adam - I do obviously enjoy the 'sit and puzzle for 90 minutes' format for GP/LMI but its nice to have a round that's a bit different Thanks Ma...

Re: Divisions A and B 2020-2021
I'm nilz on there. I should be appearing there now, I just solved the Mon and Tues puzzles. Not sure if there is/needs to be any penalty for solving a day late, although I guarantee I'll forget again before the end of the week.

Re: 2021 WPF Sudoku and Puzzle GPs
Put me in the 'Disliking the SPOLICY' camp! Definitely should've spent that time on the scrabbles instead, but I forgot they were there!
Weirdly I found the big Yin-Yang easier than the small one. As Tom surmises, I do feel like I could've bifurcated a bit earlier to get the small one out quicker.

Re: UKPA Skyscrapers Contest 25 February - 2 March 2021
Nice contest thanks David. Disappointed I didn't finish. Think I spent too long on the Sums. I did have the easy consecutive done and entered, but I didn't realise/ forgot that the interface doesn't auto-submit when the time runs out. Made no difference luckily. Glad to hear there's a masyu contest ...

Re: 2021 WPF Sudoku and Puzzle GPs
I really enjoyed this test, even if I did spend way too long factorising large numbers :roll: Some really nice underrepresented puzzle types (I'm thinking mainly of the football puzzle), and it's nice to see a strong UK showing. :) Can we claim that makes us the best 'natural' team in the world, whi...
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...

And I did smile when I read the instruction booklet and saw 'You're Missing a Six', always nice to see clever inventions bas...

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...

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'...

Given Germany are hosting the WPC this year, it may be good practise.

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...

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...
