Puzzle No. 520: Country Road

I have a lot of pending things to get to, which I hopefully do by the end of the month, including some more elaborate blog posts.

For now though, this is a puzzle.

Rules:

Draw a non-intersecting loop through the centers of some cells which passes through each region exactly once. A number in a region represents how many cells in the region are visited by the loop. Orthogonally adjacent cells across a region border may not both be unused. The black cell just means it’s a hollow, I.e., not part of the grid.

Puzzle No. 426 : Country Road

This puzzle’s quite tricky. There’s mainly one deduction though that makes things easier. As for appearances, it’s symmetry’s a bit messed up, but things are a little hectic now, so it’ll have to do. I’ll hopefully be able to update why things are so hectic by my next post.

Rules.

Rated – Hard.

Enjoy!

Puzzle No. 382-396 : Czech Puzzle Championship Puzzles

I think this was a set I wrote when I wasn’t that well. That’s not meant as an excuse, but as a warning – I tend to make things harder when I’m ill. However, some of these are also rejects from newspaper bunches for being not-too-easy (Heyawake for example) which means there’s some easy in there too. Unlike my previous puzzle set posts, I decided to find out a bit more this time, which basically means that I can add the points that were assigned to each puzzle. The Skyscrapers Pentomino was not used, but since it was not used for being too hard, I’ve simply valued it at points higher than any of the others.

The Championship had 5 rounds and then a playoff at the end. The first round had the largest time slot and so two of the hardest puzzles of my set, the Yajisan Kazusan and the Shakashaka were moved into that round. Two others, Heyawake and Multiplicative Corral were moved to the Playoff/Final. There’s no point valuing for these, but I’d put their difficulty around the LITS or the Country Road, something of a medium difficulty.

There were 25 participants, and Jan Novotný emerged as the winner, mainly by having a good playoff, as Matej Uher was ahead after the first 5 rounds (377.8 – 299.2). In fact, Jan was 4th before the playoffs, behind Jana Vodičková (332.5) and Jakub Hrazdira (306). Congrats to him, and the other qualifiers. For my round (the 4th round, valued at 110 points), the top scorers were Matej Uher (85), Jakub Ondroušek (77) and Jakub Hrazdira (62). I’m posting only my own puzzles but as a test solver for the event in general, I did have access to the other puzzles too, and the quality is quite high throughout. If you’re interested in knowing more, or you are a Czech/Slovakian interested in becoming a member of the HALAS Association (where I think you will gain access to all these puzzles), I’d suggest you contact Jiří Hrdina, who co-ordinated/organized this Championship.

Rules/links and points –

P382 : Bosnian Road (8 points).

P383 : Country Road (12 points).

P384 : Easy As Tapa (14 points) – Follow regular Tapa rules. Clues outside must be placed in the first unshaded cell in that row or column.

P385 : Fillomino (7 points).

P386 : Heyawake (Playoff puzzle).

P387 : LITS (12 points).

P388 : Masyu [Alternative] (4 points) – Follow regular Masyu rules. Additionally, the loop cannot pass two circles of the same colour continuously.

P389 : Multiplicative Corral (Playoff Puzzle) – Draw a single closed loop along the grid lines that contains all the numbered squares and does not touch itself, not even at a point. Each given number is the product of two numbers: the number of interior squares that are directly in line vertically with that number’s square (including the square itself) times the number of interior squares that are directly in line horizontally with that number’s square (again, including that square itself).

P390 : Nanro (14 points).

P391 : Norinori (5 points).

P392 : Product Heyawacky (25 points). Follow regular Heyawacky rules. Additionally, the number at the top left of a cage is the product of shaded cells in each different region, only pertaining to its area within the cage.

P393 : Shakashaka (40 points).

P394 : Skyscraper Pentomino (60 points?). (Edit – It should be noted that the puzzle in the link has “X” marks where pentominos can’t be placed, whereas the puzzle below has black cells denoting that)

P395 : Sum Skyscraper (9 points). Follow regular Skyscrapers rules. This skyscraper uses the digits 1~7. The numbers outside indicate the sum of the visible digits.

P396 : Yajisan Kazusan (40 points).

Now, the puzzles! Enjoy!

Puzzle No. 316 – 336 : Polish Championship set

I’d mentioned a few posts earlier, that I’d contributed some puzzles to the Polish Championships this year. There was an offline qualifier, an online qualifier, the finals, and the playoffs. I think there was a good share of my puzzles in all 4 of these rounds. Its pretty confusing which was used where, since I’ve not organized it that well in my folders, so I’ll just post all the themed ones together (as mentioned in that post linked to above, the online qualifier had puzzles that I used simultaneously elsewhere and were more of a hurried solution).

The theme I was working on should be pretty obvious on seeing all the puzzles. It started with the easier Tapa, which I made completely by accident while writing a bunch of newspaper puzzles, and then I just tried a similar thing with the Corral and that happened quickly too. So, just decided to go along with it, discarded those two from the newspaper bunch and started off the Polish set with them. I couldn’t really try and retry the puzzles to get the exact appearances I wanted, and this is apparent from the 2 LITS and the Killer Sudoku among other ones. The LITS is of course something difficult that I set myself to do in a pretty short timespace, as both LITS were required hurriedly for the qualifiers, and to make it have duplicated regions throughout on the first try seems almost impossible, at least for me.

Anyway, here they are. As with the Zeka set, rules are either linked to by the puzzle names or just added here. These puzzles have varying difficulties, but I don’t think anything was exceptionally hard.

Enjoy!

P316 – ABC Box – Fill the grid with letters A, B and C. The clues outside give the sequence of letters in that row or column. If the clue is a number, that is the number of times a letter appears in that position of the sequence (Which letter is determined while solving). If the clue is a letter then that letter appears in that position of the sequence (The number of times it appears continuously is determined while solving). A “?” means that an unknown letter is appearing an unknown number of times in that position of the sequence.

Puzzle No. 194 : Country Road/Masyu

So… umm.. I hope someone’s pleased to see this. Anyway, TBH, he helped me more than the other way round as I was all over the place on what type I wanted to do today.  So when I saw the comment, I just put this one together quickly, because, well, I’ve still got a lot on my plate (refer to yesterday’s pointless post). I hope it doesn’t disappoint.

On a side note, I think Country Roads with symmetric regions are very limiting in a lot of ways. But I can’t stop doing that, maybe because I like it, or maybe because I just feel lazy and this way I just need to copy-paste one half of the grid into the other and so save myself half the work. Whatever be the reason, it shall mostly continue.  Because I like it.

On another side note, I recently got my 4th salary for providing puzzles for life-365. Which means I have earned about 2-3rd of the participation fee at Croatia just through this. Cool eh?

On yet another side note, this is the 400th puzzle I have ever created, since starting on December 23rd. And I make too many side notes.

Combine ’em. Solve ’em. Enjoy ’em.

Rated – A medium-hard level puzzle made in a state of immense anxiety(not related to the puzzle itself). I make too many medium level puzzles.

Puzzle No. 148 : Country Road

Update : Same as my last Country Road, I use Nikoli rules where all rooms are visited. I had previously linked to rules of Melon’s version by mistake where that is not necessarily the case. Apologies.

I’ve uploaded a tips page for yesterday’s puzzle since it turns out it had a little non-logical part in its solve. I think the Heyawacky a few puzzles before that might be a bigger mess, so if anyone wants me to upload a revealing tip for that I’ll gladly do so.

Also, I may/may not make a special puzzle for the 150th. Not sure if I’ll have the time, since I’ve got the unpleasant and time consuming task of clearing my room and searching for certain things. Anyway, for one thing, I’ve never really thought of 150 as a big milestone, not in cricket anyway 😛 (yes, random), and for another thing, the constant 13×13 challenging puzzles have made up for that, right?

Rules for Country Road.

Rated : Hard me thinks. But then I’m still a bit raw on solving these, so not sure.

Enjoy!

Puzzle No. 142 : Country Road

Firstly, I apologize for the unprecedented double delay. Truth is, I’ve been trying to make a certain type of puzzle with a certain type of layout, and I’ve just not been able to make it work! So today I decided to give that up for now, provide some solid puzzles for now and try it again later when I get time.

So this is… not my first country Road puzzle! 😛 I made an easy one for the publishers already. Anyway, this one’s certainly not easy.

Rated : Hard for the first timer(as far as this blog goes anyway)

Enjoy!
