Cracking The Cryptic

Mark Goodliffe & Simon Anthony have a youtube channel! https://www.youtube.com/channel/UCC-UOdK8-mIjxBQm_ot1T-Q This is mostly off-topic, focusing on Cryptic Crosswords, however there is the occasional run through of The Times "super-fiendish" classic sudoku, and "deadly" killer sudoku.

Hi Mark, thanks for sharing this. It's always good to hear new puzzle ideas. Here are (from a purely puzzle solving perspective) some brief thoughts: First off, I like the name!

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

Interesting stuff David - I see the Olympiad has been around for a while, but is 2011 the earliest there has been a sudoku/kenken event? Perhaps we should add this (and also the times event) to our hall of fame?

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

Myself, Neil and David C from this parish were at the Sudoku / KenKen event this morning amongst a field of about 15 people. The format was two papers: the first a set of 8 fairly easy classics, and the second a set of 8 kenkens, two each of 6x6, 7x7, 8x8 and 9x9. The smaller puzzles were quite easy...

Re: The Hunt for Justice

Specifically the hunt seems to be 1pm to 9pm EST. Which I make as 6pm to 2am here in the UK

It is worth noting that the 21st October is during the WSC/WPC in India, so that might affect participation a bit from this parish.

Re: Play-offs

Rugby League sounds ridiculous! I think one aspect of the play-offs is it gives some motivation to some solvers who aren't going to be quite challenging at the top. From this point of view I'd certainly like to see a few more innovations like the Tour de Senec to vary the competition up a bit. I don...

Re: 2017 Sudoku GP

Results are up - I thought it was a very hard round, measured by how close I thought I was to finishing (not close at all). I also thought it was perhaps a little too "puzzle-y", although not by much. The UK ranks are a little below the norm for this year, which is a bit disappointing. Top 3 UK: 56....

Re: 2017 Sudoku GP

It's GP weekend again - perhaps a bit late but you still have til tomorrow evening to compete.

Re last month, the time slipped away from me somewhat that weekend. What with the attacks near London Bridge (10 minutes away from where I live) the whole thing completely slipped my mind.

Re: croco-puzzle

Yes, I think I understand. Instead of fixed logistic curves defined by a fixed parameter of 2, this exponent was variable. Do you know to what extent this value varied away from 2 before your change? I'm also curious about the updating factor f - is that also a fixed parameter? As an aside, I have l...

Re: croco-puzzle

Well I seem to have done very well out of this - I've been pushed up by 100 points or so. With a little less carelessness I think 3rd dan could be in sight!

Is it possible for you to explain a little more about the formula Berni? This kind of thing does interest me a lot.
