Well done Tom!

Good luck to those of you currently taking part in the online MSO sudoku contest. I made a mistake with the registration requirements - I registered with MSO, and with Discord, and with vint.ee, several days ago. However I cut it fine driving home tonight and didn't realise about needing to register...

Thank you. It was good to see Tom and Neil, and Rodders for the first time in ages. There were some other familiar MSO faces too.

I contacted The Times generic mailbox a few weeks ago to find out about the qualifiers (as I would need to qualify this year after a stupid error last year). David Parfitt replied soon afterwards: "[...] I'll be in touch as soon as I'm in a position to update you on what is happening this year." Not...

Hello. 958 ?

Even more succinctly, a sudoku is about symbol placement not structure placement

More succinctly, a sudoku is primarily about symbol placement not structure placement.

For me, I think that it is the numbers (or symbols) that should need to be placed in a sudoku, not the structural components. I am happy when regions are marked out in the beginning. I am not happy with having to mark out regions myself. Thinking about it further, I think that I would be happy to pl...

This is OK for me. The list and white junctions are really just extra constraints that reduce the number of classic candidates. Subjectively, I also like the concept (but that's irrelevant).

This is a "no" for me. I expect to be asked to fill in a sudoku grid (including whatever extra shaded/region/other rules are relevantd). I do not expect to be asked to have to construct part of the puzzle itself. For me, this example goes too far beyond just applying rules and becomes actual realtim...

I'm not sure how to insert a diagram image, so maybe I'll refer to plotting a colour-coded diagram with a RAG Status list instead (Red=no, Amber=borderline, Green=OK), with Classic in the centre, other Greens surrounding, Amber slightly further out and Red much further out This is just an illustrati...

"Or the 2011 WSC round 12, which consist of a real cube (not a 3D representation on a 2D paper)."

I feel that anything involving physical handling/dismantling/constructing/manipulation is a distraction and a gimmick.

Any set of symbols will have some cultural baggage. In my opinion the digits 1-9 have less baggage than the letters A-Z and come from a smaller set of elements (implying less likelihood of confusion for contestants and markers). I don't think there is any other relatively small set of symbols that i...

I wonder whether an Euler diagram would help the discussion? I seriously don't want to trigger a distracting Brexit discussion, but a few years ago I found that Euler diagrams were a great way of drawing out some of the subtle differences between different terms used to describe the supranational Eu...

No because of:
(a) repeated symbols
(b) bias towards those used to the English (unaccented) alphabet
(c) potentially even more difficult for markers than numbers

I still have nightmares about this round in my only WSC appearance - I'll vote No before you even post the poll

Hi Tom. How would you like us to approach a situation like this? Without having the actual discussion here, my opinion of HALLOWEEN has two distinct aspects: the use of non-numeric symbols and the use of repeated symbols. Would you like me to simply vote on the specific example you have chosen, or s...

Congratulations to Mark and commiserations to Tom

Congratulations, Neil, on an excellent pair of victories, especially as the format changed this year. Thanks for posting the results - your post was how I heard the good news!

Just to remind everyone that this year the event is at a hotel on the Purley Way and NOT at the usual venue.
