I seem to recall a close battle for the minor places last year too! For my part I'm pleased to have finally put my answer key demons to rest...

Well done Freddie, James and Neil!

Thanks for this, Tom - as I've already said to you, the puzzle quality was very high. Definitely my favourite UKSC since I started competing. I particularly enjoyed all of the classics, the OEBS, the Diagonal, the Irregular and the Eliminate.

I don't understand the answer key for 2.8 Train Tracks. The segments in row A and the segments in row B look the same length to me, so I don't know how to get 11,222 out of that.

Thanks to all involved!

Small nitpick: in the solution for Clone Sudoku in the IB, the 8 and 9 in the lower-right region are transposed.

In terms of the second example, this was my sticking point: https://i.ibb.co/3ycXNp4/doppelblock1.png My approach here was to note that the 3 in C5 and the 3 in R5 interact through their common cell - either both clues are a 1-length gap or both clues are a 2-length gap. This means that either both ...

Congratulations to Freddie Hand, who has won the UK Sudoku Championship for the first time, ending a run of three consecutive victories for David McNeill.

I also want to say thanks to everyone who took part. I know there are a number of solvers who were taken aback by the difficulty. I considered applying a warning to the contest beforehand, but I didn't want to 1) scare off people who might have otherwise enjoyed it or 2) influence how the top solver...

Hi pin7guin, Here are some examples of the rule in action which hopefully will clear things up. This situation is not allowed , as the two squares are the same size (both 1x1) and can directly see each other https://i.ibb.co/G3mQxF0/disallowed1.png This situation is allowed , as although the two squ...

Sam, In the rules for Look-Air Yajilin, "the total number of distinct squares" is possibly open to misinterpretation. I briefly wondered if it meant "the number of distinct square sizes" e.g. the intended rule is that two single-celled black squares separated by a 4-cell black s...

Haha, well spotted. I did read over everything to check that I hadn't left in anything that didn't make sense or wasn't true but I missed that one.

I won't be there since I haven't done the GP yet and am planning to squeeze it in! Hope it goes well

I did the same for Meandering Wordsearch and the 2 minutes I spent doing so was easily offset by how much easier the puzzle became to solve.

Thursdays are busy in general for me so I'll have to give it a miss if so.

Thank you!

Is there any chance of having the two sets of clues in Hashi/Hotaru Beam being a different shade? I think it would then be easier to tell them apart at first glance, rather than relying on the presence or otherwise of black dots.

Congratulations to David McNeill, who has won his 6th UK Sudoku Championship, and third in a row. David displayed impressive consistency to finish all 16 of the puzzles in 1 hour and 48 minutes - the same time it took him to do so last year! Tom Collyer also submitted answers to all 16 puzzles but w...
