Division C 20202021
Division C 20202021
Division C is open to any UK puzzler who is not in Divisions A and B, even if they wish to join in the middle of a season. You cannot be relegated from Division C into Division D, and the champion of Division C will be promoted to Division B in the 202122 season.
Like Division D, the winner of each competition will receive 10 credits, second place will receive 9 and so on.
The schedule is as follows (external competition dates will be finalised as they are released by LMI and WPF). This was edited to switch in the Puzzle Grand Prix dates for January.
12th/13th December  Advanced Fillomino and Tapa
29th January to 1st February  WPF Puzzle Grand Prix
26th February to 1st March  UKPA Skyscrapers competition
5th to 10th March  LMI Puzzle Ramayan
17th/18th April  Advanced Four Winds and Minesweeper
15th/16th May  UKPA Masyu competition
Edited to reflect swapping of Masyu competition timing.
Advanced competitions will involve the same standard types as Division D, as well as variants which will be announced in advance of the competition.
Should you wish to join Division C, please email adam@ukpuzzles.org

Re: Division C 20202021
If I’m in Division D, can I still do the puzzles in Division C and submit my times? Also, I’m running out of example puzzles in my copy of Puzzle Ninja (I’m sure that most will have heard of it), so I would hugely appreciate it if someone could give me a recommendation for a puzzle book or website.
Re: Division C 20202021
Absolutely you can submit for Division C puzzles even if you’re not in Division C.
My standard website for practice puzzles is GM puzzles.

Re: Division C 20202021
Thank you for recommending GM. I’ve really enjoyed the ones the puzzles that I’ve done so far.
Re: Division C 20202021
On the weekend of 12th/13rd December, Round 1 of Division C will be held. We will use the honesty timing structure of Division D, so you can complete these puzzles at your leisure and submit the ones that you complete in the time they take. There are more puzzles of a wider range, so they might take a bit longer than the Beginners sets.
Here are the variants that will be used alongside the classic types, and some examples.
Please ask if you need any clarification, or further examples.

Hi
Here is Round 1 of Division C of the 20202021 UK Puzzle League.
Please download and print the puzzles. You can complete them in any order at any point between now and Tuesday 15th December.
For each puzzle, remember to time yourself honestly as to how long it takes.
When you are finished all of the puzzles, or as many as you are able to, please email adam@ukpuzzles.org your times for each puzzle and the answer key for each puzzle (to ensure that you have understood how each solution is supposed to look).
If you are not in Division C, your times will be entered onto an allcomers scoreboard, which will not score points in the UK Puzzle League. If you are in Division C, the solver with the most points will receive 10 credits, the second will receive 9 credits and so on. If two or more solvers score the same number of points, then the fastest total time (spent on completed puzzles) will score the higher number of credits. If you are new to the UK Puzzle League, you can join in Division C late.
If you have any questions, please ask via email (adam@ukpuzzles.org)
Please do not discuss the puzzles in the forum until the competition is declared closed.
Have fun!

Re: Division C 20202021
I'm only just getting round to looking at the examples for these: the diagonal fillomino example has two solutions, I believe (you can swap R2C3 and R3C2 in the given solution).
Re: Division C 20202021
Thanks Sam. You’re right, that’s an oversight on my part. I’d accept either answer if that happened in the real competition puzzles.
Re: Division C 20202021
Glad I came back to this thread  the document itself says 11th  14th November so I thought i was too late. Time enough to read up on these variations again!
Re: Division C 20202021
At the end, it asks us to send the clues and the answers. What does it mean by clues?
Re: Division C 20202021
Whoops! Yes, you can still submit on Tuesday (or you can submit Wednesday daytime because I don’t organise everything until Wednesday evening), so still lots of time.
Re: Division C 20202021
Hello everyone. Round 1 is now closed.
Everyone seemed to enjoy the puzzles, and it was especially good to see so many people solve all of them, though there were a couple of errors in the solutions submitted. Thanks to David McNeill and Emma McCaughan for test solving, and Freddie Hand for the beautiful puzzle 15.
Here are the rankings:
Sam CapplemanLynes 41m7
Jeff Dick 60m0
Liane Robinson 64m6
Thomas Powell 77m8
Eva Myers 78m55
Maurice Blount 82m27
Adam Sandhu (296pts) 123m40
Tom Collyer (280pts) 43m49
Those coloured red are in Division C, so congratulations to Jeff for edging out Liane. Liane was about 5 minutes quicker on the Tapa than Jeff, so it was a very impressive Fillomino set from Jeff that led to his victory.
Other notable performances was Maurice's second place time on the Diagonal Fillomino and fastest of all on the Black and White Tapa. Liane also got a fastest of all, on Tapa 14, with all other fastest times by Tom or Sam.
Here is the league table at the moment:
The next round will be a slight difference to the advertised one, as LMI have not yet announced their Puzzle Ramayan schedule, so we'll use the Puzzle Grand Prix Round 1, scheduled for 29th January to 1st February.

Re: Division C 20202021
Wow?!
Thanks for the commentary! I really enjoyed the variety of puzzles. Was puzzle 7 super difficult or was that just me? I felt I lost a lot of time on it but maybe not as much as I thought.

Re: Division C 20202021
I wasted time on this by not thinking about it properly. As the diagonals couldn't have repeated numbers in them it was worth considering the actual size of the grid as that gave how many different numbers would be in the diagonals. With that bit of knowledge the puzzle is much more straightforward. I've just solved it again now and it fell easily.
Re: Division C 20202021
Hi everyone
Round 2 is now complete, though still open to appeals.
Isolating the Division C players from the whole list, we have
1st  Maurice Blount  226 points
2nd  Liane Robinson  194 points, 1.27.38
3rd  Eva Myers  194 points, 1.29.22
4th  Thomas Powell  188 points
5th  Keith Lothian  183 points
6th  Jeffery Dick  58 points
In the event of tied scores, the highest score in the most recent round decides. This was edited on Wednesday to reflect a new player joining the league. Welcome Keith!
The next round is at the end of the month (26th February to 1st March), with David McNeill's skyscrapers variants. An IB will be published in around a week and I'll send an email to competitors.

Re: Division C 20202021
I’m really excited for this round! I don’t know if some of these variations are original, but I really like the rule of 6 and socially distant minesweeper, as well as the triangle minesweeper rules. Although, I think in the instruction booklet, the socially distant and triangle minesweepers do not have unique solutions. Maybe I misinterpreted the rules, but here are the other solutions I found. https://imgur.com/a/svg9Q5N

Definitely multiple solutions to the two that you've mentioned.

Re: Division C 20202021
Both are unique if you clarify a certain number of mines. Triangular with 6, socially distanced with 4.
Re: Division C 20202021
Sorry guys. You’re absolutely right, those are also viable solutions to the ones you’ve looked at. I’ve had quite a few rewrites in the actual set because I’m not always great at getting them unique first time. David and Neil have been very patient with their testing  the actual set should be unique.
