24HPC 2014 Budapest 21-23 March

Postby Gyorgy ISTVAN » Thu Feb 27, 2014 10:30 pm

After 1,5 years break, the Puzzle Marathon will be held again in Budapest, 21-23 March.


Some basic information about the event: the schedule of the weekend will be the same as it's usual (see below), there will be 13 times 100 minutes puzzle sets, which is much more than you can solve during any WPC-style event. In this year Pál Madarassy (former WPC individual champion) is in charge of selecting and checking the puzzle-sets from all over the world (India, Japan, Germany, Croatia etc.).

There's a welcome dinner on Friday evening at approximately 7 pm (to be finalised later, when we have more details about the participant's flights), and later we have a Q&A session, if you have unanswered questions (the IB is published a week prior, and we're replying for your question on the WPF-forum, so normally this Q&A lasts only 30 minutes). On Saturrday the championship starts at 10 AM. On Sunday the solving time ends at 10 AM, and there's an award ceremony at 11:30 AM, which is followed with the farewell lunch.

The fees are: 180 Euros in double room and 240 Euros in single room. 40 Euros discount goes to the puzzle authors (if two person compile one set, it's only 20-20/person).
The fee covers the transfers from/to the airport, T-shirt, meals, soft drinks, coffee, tea during the 24 hours and ... the puzzles of course ;)
You can pay in cash during the championship.

If you want to participate, send your registration to istvan.gyorgy@gmail.com.
Please let us known your travelling info in order to organise your transfer from/to the airport.
Please calculate 1,5 hours for your transit between the hotel and the airport, and give also an hour for the security and passport control at the airport (if you have not just a hand luggage, another 30 minutes for check-in your baggage), so the earliest departure should not be earlier than 3 PM (Budapest local time).

Please also write your T-shirt size, and if you have any meal preferences (like vegetarian) or any other special request.

We're also please to organise your extended stay in Budapest (e.g. if you want to visit some logical live-action games, see more at: http://www.theguardian.com/travel/2014/jan/10/claustrophilia-live-action-game-budapest)

So, if you want to do some extra mental games, we're more than happy to reserve a place in one of the dozen great places - and we can also delegate some Hungarian puzzlers if you don't have enough friends to form a team for these games. Of course we're offer to play this game on Friday afternoon (and you should arrive a bit earlier to Budapest - and you should make your decision early in order to have free place in one of this games...), or staying one night longer in Budapest.

If you have any further question, feel free to ask us.

Until now 13 participants confirmed their registration for the 14th 24-Hour Puzzle Championship - but the registration is still open, so why not join to the event?

I have started to look through the instructions and have a few queries on round 4 -Tamas Antal.

Puzzle 4 - Walk Tents - this says there is a one cell width walk path fro top to bottom. In the example the middle two rows could be two cells wide. Is that a possibility in the competition puzzle?
Puzzles 5 & 8 examples are non-unique. I presume the competition puzzles will have unique solutions.
Puaale 10 - "Neighbouring letters can't be pairs". Does this mean neighbouring in the puzzle grid or alphabetically? I read it as in the puzzle grid, but the small example grid has the G & D connected.

Thank you.

Just a small note on the 3rd set, puzzle 5 - Arrow Masyu ...

From my view, it is not necessary to draw all the circles in the grid, that sentence is there only for better understanding the rules. I hope that the checkers will not insist on drawing all of them.

Dear friends,

here's the answers for your questions (some of them sent by e-mail):
Part of Tamas Antal, Puzzle 4, "Tents park": The sentence "if it is part of
the complete solution" suggests, that the six puzzles belong together somehow,
but no hint is given, how they are connected. (If I should guess, I'd say,
that one has to find out which grid belongs to which variation, but I would be
happy to have a clarification.)

your guess is correct, you need to find out which rule belongs to which grid.

I have started to look through the instructions and have a few queries on round 4 -Tamas Antal.
Puzzle 4 - Walk Tents - this says there is a one cell width walk path fro top to bottom. In the example the middle two rows could be two cells wide. Is that a possibility in the competition puzzle?

It's possible, just need at least one road (no need to draw)

Puzzles 5 & 8 examples are non-unique. I presume the competition puzzles will have unique solutions.
The competition puzzles are unique:)
We apologise for non-unique examples.

Puzzle 10 - "Neighbouring letters can't be pairs". Does this mean neighbouring in the puzzle grid or alphabetically? I read it as in the puzzle grid, but the small example grid has the G & D connected.
alphabetically (ie you can't connect DE or CD)

Part of Nikola, "Arrows Doubleblock": What about two largest numbers in the
2x2-square? Does it never occur or does the arrow only point to one of the
two, or does it point in two directions?

You are right, it never occur.

Part of Bram/Hns: "Pentominous": I found an alternative solution to the
example - see attached file - or more likely, a rule is missing, probably
saying, that two given letters may never be part of the same pentomino.

Yes, the rule is missing.
"No pentomino can contain more than one letter"

Part of Russia: The points are missing. Will we get to know them in advance?
Yes, now you can download the updated version with a cover page.

Dear friends,

we got some more questions by e-mail.
Here's the answers:

Tamas, Tent Park:
It’s not stated explicitly, but I assume the usual “exactly one tent per tree” rule holds? For the bit tents, “exactly one tent part per tree”?

Yes.

Matus, Multiple Yajilin:
“The […] white cells must all be connected”: Does this mean that all white cells must connect along edges, even if they’re not part of the same loop? The example doesn’t make use of that condition.

To be honest, I do not understand the question, but there are no such rules in that puzzle. The only difference between that and usual Yajilin is the fact, that there are more loops than one.
All white cells must contain part of loop. There is no white cell that is not connected with any other white cell.

Matus, Arrow Masyu:
- I assume that all possible Masyu clues are counted? I’d state the rules as follows:
Draw a single non-intersecting loop that passes through some cells. Place all Masyu clues that are valid for this loop. Then the arrow clues count the number of Masyu clues in that direction.
Is it necessary to draw the Masyu clues for a solution to be marked correct?

No, it is not necessary.
(there are some masyu circles without any arrow pointing at them)

RUS, Fill 2x2
“Same” is without reflection or rotation (both uses)?

"Same" here means that these areas are completely identical - the same shape, size and orientation.

Tawan, Encrypted Mines:
What does “all possible numbers” mean?

I will give all possible numbers that A-E could be.
In this case, A-E will be represented by 0-4.

Couple more questions?

In Tamas Antal's round, in the ABC connection can we assume that all cells will be used?

In the Japanese round in the first Zenbeya puzzle does the symmetry apply to all regions, even those without a clue number (the example implies this)

Thank you.

I think the question is, are the black cells allowed to cut off part of the white cells, so that all white cells don't form a single area (think for example hitori and heyawake).

So is a situation like this allowed?

Thank you Bram, it is a good question.
I haven´t thought about this situation. But the answer is: "Yes, it is possible." But there will be no such situation in the competition puzzle (as you may deduce from my reaction).

Have a nice day
