# Puzzle No. 484-487 : Polish Qualifier Puzzles [Ex-Contest]

Check this post for reference on this blog’s 3 main types of posts from now on. I’ll post smaller sets like this one here, and keep I’m hoping to start a patronage system of my own for bigger sets. More on that later.

Right, just about got this in today. I won’t be home over the weekend, so whether I get a sample of the Instructive tagged post out depends on getting an internet connection where I’ll be staying. I’ll be back on Monday though, so will have it up at latest by Monday night.

This set might seem to have some tough puzzles for a National qualifier (not finals), but I was told that there were many easy puzzles already. Two of the puzzles are types I saw in a book purchased from team Japan at the WPC. It is a collaborative work featuring Serkan Yurekli and many Japanese authors. I’ve changed one rule slightly for Heyawacky block (more an omission than a change) but I prefer it this way personally. Anyway, here they are. Enjoy!

Rules –

484 – Yajilin.

485 – Heyawacky Block – Blacken some cells so that all remaining cells must be connected orthogonally. Any single horizontal or vertical line of white cells cannot traverse more than one thick line. Numbers indicate the amount of black cells in that region. If there is no number, there can be 0 or more black cells. Inside each region, all black cells are connected orthogonally. But black cells must not be orthogonally connected beyond the border lines.

486 – Nurikabe.

487 – Snake BY – Draw in the grid a snake, not touching itself, even diagonally. Each outlined region must contain exactly 3 cells occupied by the snake. The regions that contain the head and the tail of the snake are marked by grey color.

# Puzzle No. 469, 470 : Regional Tapa, Regional Snake

I took a week long break from puzzle construction, which was a little “forced”. Now I’m starting again from tomorrow,  and I want to start fresh, so discarding all my “reserve” puzzles and starting new on everything, as I like to do after a break.

The Regional Tapa isn’t that difficult but the Snake is.

Rules –

P469 – Rules of Tapa. Additionally, a clue also indicates the length of shaded cell groups in its region (in the exact configuration as the clue). Some regions may not have clues and have no restrictions. A “?” can stand for any number, but the number(s) needs to be constant for the clue cell as well as the region it is in.

P470 – Find a snake in the grid whose body consists of horizontal and vertical segments. The snake’s body never touches itself, not even diagonally. The head and tail of the snake are not given. Numbers in each of the regions surrounded by thick lines denote the number of cells occupied by the snake in that region.

Enjoy!

# Puzzle No. 453 : Regional Snake

I’m still a little busy, and its looking like that will continue through November. So, I’m just gonna post the puzzles I wrote for team practice before WPC, one by one. I will post write-ups too, somewhere in between all that. As of now, I’m mainly devoting about 5 minutes a day of my schedule to the write-ups, so I’ll fill them in little by little 😛

I decided to post the Regional Snake today. It has, quite literally (!) a narrow solve path. But I still think it uses the regions nicely.

Rules – (copied from the WPC Instruction Booklet, Serbian Round (R7)) Find a snake in the grid whose body consists of horizontal and vertical segments and its total length is 45 cells. The snake’s body never touches itself, not even diagonally. The head and tail of the snake are not given. Numbers in each of the regions surrounded by thick lines denote the number of cells occupied by the snake in that region.

Rated – Hard.

# Puzzle No. 438 : Bosnian Road

Tapa Season (TVC, CTC) is past halfway and now getting really interesting at the top in both competitions. I’m really happy with my improvement this year from last year’s inconsistencies. Hoping to end well now. TVC XV is going on this weekend.

Nothing much to say about this puzzle. Just that I like the top opening, although its not that tricky to spot.

Rules

Rated – Medium.
