Re: United Kingdom Competition Registration Protocol

Good point. I've observed this too - it would be good to standardise to "United Kingdom" in my opinion. "UK" is not a universal abbreviation (in the UK it is, but not everywhere else).

Re: Nikoli Selection - LMI July 2011 Puzzle Test #1

I would like to know more about kakuro and uniqueness too! I read Steve as saying that after the Kakuro he returned to the Suraromu and used uniqueness on that, where of course it helps a lot. I normally avoid Kakuro in competitions but trying Tom's example beforehand persuaded me that he'd use ver...

Re: Nikoli Selection - LMI July 2011 Puzzle Test #1

I really enjoyed all of these too - thanks Tom. I particularly liked the Suraromu - I often find you have to deliberately not use uniqueness on these so as not to make them trivial, and while it was a good technique on this one it far from solved it in a single move. :)

Re: UKPA Puzzle Cruise (2-3 July 2011)

I also thought that Pentomino Pool was an excellent puzzle when I tried it afterwards. Very nice and logical. I was kicking myself for persisting on the Kakuroh when this is a beautiful (and actually quite easy if you see how to start) puzzle.. Yes, I was too scared to try it because I thought it m...

[[[[[Bermuda Triangle can be solved as follows:]]]]] Thanks very much for taking the time to post that! In which case that's great, since that's exactly how I did it afterwards.

Re: UKPA Puzzle Cruise (2-3 July) ** started **

The worst puzzle formatting was on the KakurOH. You MUST use the slash notation for every clue, or at least position the horizontal clues and vertical clues in different spots in those cells. There were a lot of phantom clues in there. I'm glad you said that because I thought I was dumb - I spent s...

Hi all, in puzzle 8 I can’t understand the following statement: “Arrows represent tides that must be followed correspondingly.” Think of it as a one-way street. If you use that particular cell as part of your path, you can only travel in the stated direction. A possible confusion here is that you n...

Re: Any interest in a UK croco-puzzle ladder?

I don't use croco puzzle, but from occasional browsing of this thread I understood that if your play time was much shorter than the time since initialisation, the time from initialisation took priority? Doesn't that explain it? :)

Say a given 4-cell long ship is marked 1234, it can appear as 1234 or 4321 (horizontally or vertically).
Which would, I think, be fairly called reflecting it. :) So reflection is allowed.

Re: 2011 UK Puzzle Championship (25-26 June 2011)

Good Neighbours - so if the grid were 515 555 the top row would be clued as 11 (and not 6)? There are only 2 distinct entities (in your example, a monimo(?) and a U-pentomino) in the top row, so the clue would say 6. In your answer to David's previous question, which explicitly asked exactly this, ...

I think the example solution key to Clueless Tents (#8) should be 31222222. On various puzzles the example row/column entries are not marked on the puzzles.

In Spanish Armada (#16) what does the rule "The orientation of the cannons must be respected, however, the 1x1 ships (which cannot be described as submarines as those did not exist at the time of the Armada!) can have the cannon oriented in any direction." mean?

Re: 2011 UK Puzzle Championship (25-26 June 2011)

Correct. Operations should be carried out in the order they appear in the sum. eg "8 - 4 : 2" = 2. (not 6) Since this is a UK test which we want to be open to the general population, shouldn't we use a division symbol that most people would actually recognise as one? In the WPC last year it took me...

In Turn of the 90s (#4 and #5) is the set of rules complete?

Re: 2011 UK Sudoku Championship (11-12 June 2011)

Sure. I guess I'd simplify my comments by saying there are two axes of difficulty with a sudoku. They can have easy or difficult (or non-existent) logical steps. They can have a broad or narrow solving path (meaning fewer places to make the next deduction). These have a low score on the type of ste...
