Re: WPF Sudoku GP 2020

I did not enjoy that round for many reasons - and looking at those results I don't think I was the only one!

Re: WPF Sudoku GP 2020

I wouldn't be totally convinced that's not just a coincidence Sam - at any rate this tic tac toe puzzle seems a bit friendlier and less reliant on second order logic than yours, although some of the same hidden gimmicks still apply (e.g. orientations of even winning lines). I wonder what this Kropki...

Something akin to the Japanese Heads Up puzzle league would be pretty cool, I think.
Could you give a brief summary of what that is and how it works? I’ve never heard of that

Re: Some puzzles for your solving pleasure

Excellent to see more Latex use :) How are you drawing up the puzzles though Sam? At a guess they look like png files from (possibly Excel) screenshots?

Re: WPF Puzzle GP 2020

I’m relatively sure wei-hwa draws up all the grids himself for the GP booklets... of course if you happen to have lots of different templates for different styles then maintaining consistency is difficult (although still very much desirable!)

Re: Where should a beginner start with puzzles?

Recent competitions are a good start - even if you don't solve many of the puzzles, lots of more experienced solvers will have them fresh in the memory, and will generally be happy to explain how things work if you ask

Re: WPF Puzzle GP 2020

Yes I got caught out by the domino puzzles being the wrong way around. Hopefully they’ll realise I have the right code in the wrong place and give me the points.

From the forums, it seems Kota also has this problem so I don’t feel quite as daft for missing this

Re: UKPA Hybrid Sudoku Contest

My guess of 40 minutes for the winning time wasn't too far off the mark. I didn't enjoy killer-clone at all - I must have spent half an hour staring at it without getting a single number placed, which ended up being very frustrating because otherwise I was solving quite well. Turns out the trick was...

Re: WPF Sudoku GP 2020

I'll have to go back and have another look at the classics. I made a very conscious decision to avoid quad max and more or less work backwards. There was a point where I wasn't sure I was going to get back through all the classics, but I seemed to get through them OK, but my focus was very much on g...

Re: WPF Sudoku GP 2020

Well known is probably stretching things a bit :roll: personally I think that would apply to Extra Regions, Fortress and maybe Renban. I much preferred the balance of types in round 2 to be honest :D

It's not what I'd really call a 'logic' puzzle, but I've seen far worse sequences.

Re: WPF Puzzle GP 2020

Also note that for whatever values you put for the sequence, there will be a 6th order polynomial you can construct that fits the sequence. It’s a terrible puzzle for the GP.

Re: WPF Puzzle GP 2020

Quite annoyed to miscount 7 as 6 for the 59point nurikabe - that would have moved me up to 40th. I think it’s going to be pretty competitive behind Neil and James this year!

I think me and Neil are planning on coming - we might even get our round together! The timing is a bit annoying from a UK perspective - there's a bank holiday on Friday which is doing funny things to the prices of flights as a few people are fancying a bit of a jolly in Budapest. My current plan is ...

Re: WPF Sudoku GP 2020

In general the classics points have been a bit weird. At a guess I’d say for any given puzzle one of the testers had a great time, perhaps after guessing or even restarting. I doubt that was the preferring for any one individual tester either! My strategy has been to ignore the lower point classics ...

Re: WPF Sudoku GP 2020

yeah I suspect that hidden clone caused more than a few people a spot of bother. I’m not at all sure I properly tweaked all of the logic. I just about tweaked that the regions might overlap, tried the top left shift and that just about worked with a bit of experimentation. Not sure how you’d have ru...

There were lots of points for this round wich kind of meant puzzle selection was key.

Bad luck with answer keys Freddie, I assume 10/14 isn't all wild speculation and...

Round 1 results. I thought that was pretty tough, and that seems to be backed up by only 12 solvers getting a full 13/13. I hope the GP's aren't going the same way as the USPC and the so-called "Snyder Effect" with the difficulty ratcheting up year on year. Top 3 UK preliminary results are: 39. Heat...

Re: Different Neighbours

I find the quickest way to solve harder examples is just to take a guess and hope you get to a contradiction sooner rather than later. There are a few techniques you can use before you need to resort to that though. Notating where numbers go across two adjacent cells can propagate very quickly acros...
