Perplexible

Hai everyone!

I haven’t seen any puzzles like this before, do comment if you have.

Outside the grid are laser emitters, marked with > .

The goal is to place mirrors inside the grid, according to the rules:

A mirror is  placed diagonally inside a tile, reflecting the laser that hits it by 90 degrees (or pi/2 rad, if that’s your thing). The mirrors are double-sided, both sides reflect.

The numbered tiles tell both how many lasers pass through that tile and how many mirrors are adjacent to that tile (Minesweeper style).

Every mirror is hinted by a number; there are no hidden mirrors. Also, the mirrors may not be placed on numbers.

Every mirror must be hit by at least one laser.

Every laser must pass through at least one number. Lasers may not hit laser emitters.

Hopefully the rules are comprehendable!

Fillomino Borders. Divide the grid into regions (polyominoes) such that no two regions with the same size touch orthogonally, and put a number in each cell describing the area of the region it is contained in. Additionally, some clues appear:
– Inequality signs must be satisfied by the numbers in the corresponding two cells pointed by the signs.
– Black circles indicate that one of the numbers among the two cells a circle touches is exactly twice the other number. (Kropki circles)
However, the converse doesn’t apply; not necessarily all inequality signs and black circles that can appear are present.

Answer key: Enter the contents of the eighth row (counting from top, describing from left to right), followed by a comma, followed by the contents of the eighth column (counting from left, describing from top to bottom). Only enter the units digit (the last digit) of each cell; for example, for a 10, enter 0.

A new year special of course, with the 2013-1-1 theme. But apparently it’s missed by one of my blog’s solvers. Ya, I forgot to schedule this post for Perplexible, I only remembered to schedule for my blog 😛

Yay first post by chaotic_iak *insert shameless advertising he– wait I already have*

To begin my double-posting adventure, I’ll crosspost my Puzzle 39 here.

Liar Slitherlink. Follow regular Slitherlink rules. In addition, exactly one number from each row/column is false.

Answer key: Enter the number of cells inside the loop in each row from top to bottom without separators. If there are 10 cells inside the loop, put 0.

Puzzle 1: Liar Slitherlink

Unlike in my blog (linked above), I will not write stories for each puzzle here. Go there for stories. I will also post a puzzle here only if I think it’s good. Well, this one is average in my current standards, but it’s a good introduction to my style of puzzles…maybe.

…or well, maybe I’ll post here more often, because I can’t have the fave/solved API in my WordPress blog. As you see above, I have an answer key here. Blah why I can’t have the API in my WordPress blog. *insert rant here*

My solving skills had been stagnant for some time. Truth be told, I was getting slower with puzzle types which require speedy pattern recognition, like sudoku. Rather than fight what is likely age with practice, I decided to improve on the harder end of the spectrum. I took up writing puzzle fragments, as a way to learn things I had been missing as a solver. Eventually, the fragments turned into full puzzles, and I grew to love writing as much as solving. Obscure Japanese types come easier to me, so I am sharing one of those with Perplexible. You can find more half-decent puzzles I write on my blog. And in case you’re wondering, yes, my solving has gotten better with writing.

Draw a path from IN to OUT, visiting all 5 ice barns (the blue regions) along the way. Out in the field, the path can turn freely, but cannot cross or otherwise touch itself. Inside ice barns, the situation is reversed: your path can cross freely, but you cannot turn at all. Parts of your path are given, as well as the direction in which you walk over them. Enjoy.

Here is a new Slitherlink puzzle for you to try. This puzzle is based on Floret Pentagonal Tiling, which was suggested to me by Danny Sichel. The additional clue styles (ampersand and dollar sign) were inspired by David Millar’s excellent “Area 51” puzzles, which you’ll find at The Griddle. If you like this puzzle, you can download six of them here.

Fill in some of the dotted line segments to form a meandering path that forms a single loop. The path does not cross itself, branch, or touch itself at corners. The numbers indicate how many line segments surround each cell. Empty cells may be surrounded by any number of line segments.

A dollar sign ($) indicates the cell is inside the loop. An ampersand (&) indicates the cell is outside the loop.

There is one unique solution, and you should be able to find it without guessing. You may find it helpful to mark segments that cannot be filled in.

Unlike the others here, I am not a prolific puzzle author… or a speed solver… or even an expert solver.  However, like the other authors here, I love puzzles.

My current favourite puzzle types are slitherlink, masyu, and other loop type puzzles… and their variants. (Yes, I spelled favourite that way intentionally – I am Australian).  In addition to posting up some puzzles for you to solve, I also intend to put up some tutorials aimed at pure beginners.

I planned to do a slitherlink tutorial, but there are a number of good ones out there already (particularly the Conceptis one), so felt there was no need to reinvent the wheel.  Instead, you can practice those techniques on the below puzzle: (Easy possibly tending towards Medium)

My first slitherlink

This is my first upload here. To begin with its a medium level Diagonal Sudoku. Hopefully soon we might see some different and interesting variants too.

Hi Folks,

This is my first contribution to Perplexibles. I’m calling this a “Septigon Slitherlink”. This is 7-fold variation of the Snowflake Slitherlinks, one of many unusual Slitherlinks that you can find on my puzzle site, Krazydad.

Jim of KrazyDad.com fame suggested I kick off this blog with an inaugural post to set some sort of direction for it. What I envisioned is being able to provide a venue for established puzzle authors and occasional authors or newcomers to mix it up and just have a place to post puzzles and share them with an audience. That’s what I wanted when I started The Griddle 6 years ago, when a friend helped me get hosting and start fleshing out the site with content and code so that I could share the puzzles I’d made for friends, classmates, and teachers with a whole new audience.

So I guess that’s where I’m coming from as far as the spirit of the blog. As far as actual content and style, I envisioned something more like what Thomas Snyder, Palmer Mebane, and Grant Fikes do, with straight up puzzles, and maybe a bit of editorial commentary here and there. In fact, this puzzle is inspired by puzzle variations seen in motris’s blog, as well as a hybrid type I’ve posted on The Griddle and in Sudoku Xtra in the past. It’s a 6/9 Flip Slithery Sum Sudoku, which is a mouthful.
