Re: 2019 USPC

I've submitted 155 points worth of answers, and have been slowly trying to make my way through the stuff I didn't try. Very hard test this year!

Re: WPF Sudoku GP

What a horrible looking variant. I can only hope the instruction booklet is a bluff and that the competition puzzle only has 2x2 regions. Even in that case I feel like you are stretching the idea of what makes a good sudoku variant pretty far. The fact this needs a 2nd attempt within the IB to expla...

Mark Goodliffe 2455 - 6 scoring rounds 66. Jeremy Kong 2394 - 6 scoring rounds 130. Matthew White 17...

Re: WPF Puzzle GP

Overall UK standings with 1 round left to play: (I'll go as far as the top 100-ish) 18. James McGowan 3230 - 6 scoring rounds 46. Neil Zussman 2479 - 5 scoring rounds 54. Saul Glasman 2362 - 6 scoring rounds 56. Tom Collyer 2355 - 6 scoring rounds 77. Adam Bisset 2028 - 6 scoring rounds 85. Sam Capp...

Re: WPF Puzzle GP

They look a bit more sensible now.

35. James McGowan 452
58. Tom Collyer 390
63. Adam Bisset 381

Those top scores are a little disappointing from a UK perspective, but good to see 15 UK competitors in total!

Re: UK Sudoku Championship 2019 / WSC Qualification

It always makes me very sad to see OEBS presented without the kanji characters - I don't know why :(

It's fair to say the solving path for these puzzles can end up being quite linear. I did enjoy playing with the partition trick in rows 3 and 4 though!

Re: Results: 2019 UK Puzzle Championship

Well done James and David! And many thanks to Liane and the authors for the organisation I'm pretty disappointed in the answer keys. I don't believe the 1 character typo in my Masyu key was really worth the -60 points I was awarded. The fact that so few people ended up without any kind of answer key...

Re: UK Puzzle Championship 2019 / WPC Qualification

Liane - re answer codes, the instructions provide fairly clear detail about what the answer keys should be - e.g. for cave: Answer Key: Going clockwise from the top left corner enter the area of the groups of cells that are connected to the outside of the grid that are not part of the cave, separate...

Re: Results: 2019 UK Sudoku Championship

This is the first year by my reckoning where we've had two UK finishers - it doesn't happen all that often and it's a great achievement to pull it off. In general the level of competition was very high, which is particularly pleasing from a personal perspective - not least because a couple of people...

After the absolute shambles with the answer keys, the preliminary results are now available. I cannot understand how these are not being checked and verified properly BEFORE the round starts, let alone after it finishes. All's well that ends well I suppose. Top 3 UK: 17.

Again the scores were (somewhat dubiously) normalised to the top scorer (Ken Endo, for each of the 6 rounds), and the best 4 from 6 were counted to give a final score out of 400 here: h...

Re: UK Sudoku Championship 2019 / WSC Qualification

The instructions for Odd/Even Sudoku begin with the phrase "in each grid..." - does this mean there will be multiple grids, or is this a remnant from instructions originally written for a Linked 6x6? Yeah I'll fix that. To be absolutely clear, Puzzle #1 is a single 6x6 grid with Odd Sudoku rules, a...

Re: WPF Sudoku GP

The main thing is to narrow down the cells that can/cannot be the removed cell along a palindrome line. Work out which cells are the possible "mirror" cells along a line based on which cell is removed, and narrow down the possibilities based on which pairs can't contain equal values. That becomes e...

It’s usually a couple of weeks afterwards (as a rule of thumb we aim for 2nd and 4th weekends in June), but I’ll leave Liane to confirm
