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!

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?

Re: Puzzle Alphabet - 08.-12.05.

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 :lol:

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...

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: 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.

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