Re: Results: 2020 UK Puzzle Championship
Wow, that was close (and fortunate). I predict many victories for you in coming years Freddie, with Neil and I not far behind. 8-) Which is great news for the strength of the UK team! Thank you to Ashish Kumar, Bram de Laat, Hatice Esra Aydemir, David McNeill, Nikola Zivanovic, and Prasanna Seshadri...

Re: Puzzle Ramayan - 2020
Well done Freddie! When I last looked it said you spent 16 attempts and 50 minutes struggling with one puzzle. Was it a bad answer key in the end?

Well done Freddie!
I thought it said 11:59pm finish, not 11:59am, so I started at 11:53am and found out two hours later that it didn't care about my answer keys

Don't get their hopes up Tawan, my Google-fu is just too strong. But they are welcome to compete for second place!

Re: Different Neighbours
Yes, obviously finding points where 4 cells meet help you propagate information quickly. Another thing that sometimes pops up is having a chain of cells where every 2nd cell must be a 4. If this chain loops back on itself then it must be even length, so you may be able to rule out options that would...

Humble Bundle Puzzles
I just spotted on gmpuzzles that there was a bundle of ~30 puzzle and other books last week, which I am sad I missed. After missing two similar bundles over the last 3 years, I had asked Humble to email me about every new bundle... except no email for this one, I don't know why. Did anybody here get...

Re: Arrows
Originally I was only going to post about notation, but then decided to start solving the puzzles as an example. I hadn't read Freddie's interesting posts at that point, so have repeated some of his observations in my own words. I haven't thought about that 4-1-3-5 square logic before, a great start...

Re: Arrows
I have a fast notation. I use a small ruler, and quickly draw a long line wherever I know an arrow points. Each 'row' can have 0, 1, or 2 lines along it. Initially it's not important to know which direction the line comes from. e.g. let's say there is a 6 and a 1 that can see each other (same 'row')...

Re: WPF Puzzle GP
Nice work Sam! I had a bad start, I'd practised for the big Slitherlink at the end, but after 25 minutes I'd broken it 5 times, printed it twice, and made myself move on to start getting some points elsewhere. During my guessing start I thought I'd proved that the bottom-right cell must be in the lo...

SOTR Holiday Quiz 2018-19
Similar to previous years, Tawan has written a puzzly quiz on his blog.

One puzzle they allowed a couple of correct answers, due to different assumptions made by people. And one true optimiser...

Re: PuzzleUp
I played in 2013. Most puzzles were fun and enjoyable. But the contest ends up decided by the few frustrating ones. A lot were optimizing style, so I remember some ambiguous rules where you're not certain which answer to submit. I also remember poorly created optimizers, where the obvious easy answe...

Re: [SOTR] End of year events
Thanks Tawan, two great contests.
I was quietly confident in my Scattergories skills for the Hurdles...
Turns out I was completely wrong, and finished down the bottom of the leaderboard!
But the quiz was fun, good for people that enjoy puzzle trivia.

The 12 pages can be joined together to make a large 'map'. At the moment I am looking at constructing some French coat of arms, and a list of galaxies ...

Re: BBC Radio 4 - Puzzles for Today
The solution briefly mentioned Fibonacci.
That was referring to the observation that the the number born today equals the number born 2 days ago plus the number born 3 days ago.
So that gives a Fibonacci-style sequence, and from that sequence t18 + t19 + t20 = 200.

Re: Puzzle GP question
I think it depends what they think the rules mean... I'd just ask them.
It's also possible they made a mistake?
