Puzzle #18

This is a Heyawake puzzle. 

Difficulty: extreme

Theme: Filled Empty Space

Puzz.link link. 

Recently learned about an advanced Heyawake deduction. Here's my take on it. In addition, this puzzle requires bashing (or some deduction I haven't figured out yet). That's why this puzzle merits an "extreme" rating and not merely a "hard" rating. You have been warned.

Many thanks to rob and Freddie Hand for proving this unique.

Puzzle #17

This is a Castle Wall puzzle. 

Difficulty: medium

Theme: Logical

Puzz.link link. 

Just a puzzle I decided to make, using a Castle Wall deduction I don't seem to see too often. In general, I find that most Castle Walls available tend to use only deductions I consider "easy", so hopefully this will introduce you to a deduction you might not have known. Then again, given who likely reads this blog, I'm guessing that most of you already do know this deduction...

Rules link is to MellowMelon's blog; he created this puzzle genre. I'm sure there's MUCH more potential in this genre than the deductions I already know of and have seen elsewhere, though.

Puzzle #16

This is a Cipher Hashiwokakero puzzle, a variant of Hashiwokakero. In addition to the rules of Hashiwokakero, each number has been replaced by a letter. Different letters refer to different numbers, and the same letters refer to the same number.

Difficulty: medium (not actually an Evil Zinger)

Theme: Bridge X-tension

Puzz.link link. (Note: Because Puz-PRE does not use letters in Hashiwokakero, all Xs in the puzzle have been replaced by blank islands in the link. Puz-PRE does not have the "same letters refer to the same clues" constraint programmed in, so the solver may mark incorrect answers as correct.)

Puzz.link does not support letters in Hashiwokakero, I had to manually add all the Xs in Paint.NET.

So yeah, this puzzle isn't quite as EZ as a normal Evil Zinger as I would have liked. Shame.

Puzzle #15

This is a Masyu puzzle.

Difficulty: medium

Theme: Logical

Have a Masyu puzzle I constructed on request from an acquaintance. No clue how often I'll keep updating this blog, but I think I have something for here that I should probably post at some point.

Puzzle #14

This is a Double Choco puzzle. I can't be bothered to write rules pages for every single genre that I come across any more, so the rules are below.

Difficulty: hard

Theme: Valentine's Day

Puzz.link link.

Divide the grid along the grid lines into orthogonally-connected regions. Each region should have exactly one grey half and exactly one white half; each half-region should be orthogonally connected, and the two halves should be exactly congruent. Numbers indicate the size of the half-region containing them; a region can have zero, one, two, or more numbers inside it.

Apparently Japanese Puzzle Twitter is making a bunch of these for Valentine's Day, so I thought I'd join in the fun. However, the latter half of the puzzle was difficult to finish off and I ended up enlisting the help of Puzzlers Club. Thanks to ManyPinkHats for coming up with a good end. It's still quite casebashy, though, so you have been warned.

Puzzle #13

This is a Go puzzle.

Oh wait no, it's actually a Masyu. (Click on image to get a Masyu grid. With hope, this will work, though I'm not immediately sure as Blogspot's "Preview" option doesn't allow you to click on links.)

Yes, that's right, just click on this and you'll get a version of the puzzle that's on an actual Masyu grid instead of a Go board.

Difficulty: hard

Theme: White Wins

I made a joke when watching someone stream Go (aka Baduk, aka Weiqi), about Go positions actually being Masyu positions. Several weeks later, the idea was still bobbing around in my head, so I made this weird puzzle to go in a post on /r/badukshitposting. It also involves repeated application of a trick that should be known to all intermediate/advanced Masyu solvers.

(To save you unnecessary checking, there are no "3-white-circles-in-a-row" configurations in this position.)

Puzzle #12

This is a The Witness puzzle-- Hey, someone's peeled all the stickers off this one!

Difficulty: Medium

Theme: Solvable

The Windmill link (Note: Due to the nature of this puzzle, you will have to input the polyominoes yourself.)

Just something I came up with this morning. Hopefully it's enjoyable and sufficiently within the spirit of the game.

Hunt Puzzle #2: Deceptive Diagramless

This is not a logic puzzle. Yes, I've jumped the shark again (for another post).

Note: You will probably want some form of graph paper, square paper, crossword-constructing program, spreadsheet software, or some tool for inputting things into a grid to solve this. Some blank 25x25 grids are provided with the PDF download, but this does not imply that the size of the grid is 25x25; the size of the grid is for the solver to determine.

The final answer is a single word, thematic to the puzzle.

Difficulty: Hard

Theme: (To be discovered while solving.)

ERRATUM: At 19/04/2018, 08:33, the clues 17A, 34A and 1D were amended, as an earlier version of the puzzle was uploaded by accident. The PDF has been updated to match. Your progress should not have been affected.

Exams are coming up in a month (again), so expect what little output there is now to dwindle (again). Hopefully I can get back to making more puzzles afterwards (but don't count on it, again).

Yes, I just copy-pasted most of this from the previous Hunt Puzzle. :P

Puzzle #11

This is a Ciphered Clue Tapa puzzle, a variant of Tapa. In addition to the rules of Tapa, each clue has been replaced by a letter. Different letters refer to different clues, and the same letters refer to the same clues. (Note that a clue may be composed of multiple numbers, unlike in regular Cipher Tapa where each letter corresponds to a single number.)

Difficulty: Evil Zinger

Theme: The most X-hausting Ciphered Clue Tapa ever!

Puz-PRE link. (Note: Because Puz-PRE does not use letters in Tapa, all Xs in the puzzle have been replaced by question marks in the link. Puz-PRE interprets "?" as meaning "a single number", and does not have the "same letters refer to the same clues" constraint programmed in, so the solver may mark incorrect answers as correct and correct answers as incorrect.)

Because Puz-PRE does not use letters in Tapa, I had to manually go in and edit all the ?s into Xs. Bleugh.

Anyway, as with my previous Evil Zinger, I don't blame you if you've stopped trying after 10 seconds. Remember to prove uniqueness!

Rules of Tapa

Shade some empty cells (at least one) such that:

1. All shaded cells are orthogonally connected.
2. No 2x2 block of cells is entirely shaded.
3. Numbers indicate the length of consecutive shaded blocks in the 8 neighbouring cells. (For instance, a "2 2 1" clue indicates that in the 8 cells surrounding the clue, there is a block of 2 consecutive shaded cells, a block of 2 consecutive shaded cells, and a block of 1 consecutive shaded cell, with blocks being separated from each other by empty cells.)

Below is an example and its answer.
