Puzzle #336 - Failed Practice (Cipher Skyscrapers)

The third round of the Puzzle Grand Prix was held last weekend, and in some slight preparation for the puzzle I was most scared of, a Cipher Skyscrapers, I made one. But then the ending didn't quite work well without a hacky patch and then I didn't notice that the patch broke everything so there were 0 solutions... which I suppose matches my GP experience as I finished the round. But I broke the Skyscrapers and had to redo it and also had answer key errors on both Shakashakas resulting in a (for me) poor showing. Hopefully I can make that up in future rounds and get a clean finish on a tough one.

Anyway, solve as a regular Skyscrapers puzzle where each letter (A-D) stands for a different number.

Puzzles #329, #330 & #331 - Puzzles from Concentrate

I know, I know, I didn't put the puzzle types in the post title today even though I usually do. In my defense, writing out Cipher ShikakuFive?Cells and Ringring would have made it way too long, even for my standards, so you'll have to settle for the tags. These were made for or around the time of Logic Showcase 22, either as entries or in response to people discussing entries. The requirement was to make a puzzle using 36 or less cells.

First up, a Cipher Shikaku. Standard Shikaku rules, except each number has been replaced by a letter, different letters represent different values and the same letter must represent the same value. Pretty obvious why I rejected this one- I had 3 that I liked a lot more. There's not much substance here though it's pretty amusing that it works at all.

Secondly, I tried revisiting one of the very first puzzles I posted on this blog, a Fivecells/Palisade puzzle where the areas must be size 1-8 exactly once each. I couldn't quite get something overall satisfying out of it- everything felt too clue dense and my first attempt was broken. After it was brought to my attention, I made this antisymmetric one to replace it- low difficulty but it has a nice flow.
Also, someone entered a Fillomino variant where each shaded cell must contain a different value- which is an idea I wish I thought of. I wasn't quite able to make one of those I liked, either, though I did make one that worked that I preferred to the showcase entry. Maybe I'll have one of those to share soon?

Lastly, here's a Ringring. Low clue 6x6s were being discussed, and an idea I had didn't quite work on that size grid. So I tried it on an 8x8 and it didn't play nice, so I tried a 7x7 which was just right.

Puzzle #144 - ABC in 3D (Cipher Nurikabe)

So, I made another Nurikabe. On a cube. That's also ciphered- each letter represents a different number.
No puzz.link puzzle link today, it just really doesn't work for this.

Puzzle #101 - Cipher Matchmaker

I signed up for the Puzzlers' Club Secret Solver event this past December, and was tasked with making a puzzle for pwahs, who is one of the top solvers at the WPC. That was intimidating. From what little I knew from the signup spreadsheet, I knew that the best type of puzzle to make would be a shading puzzle of some sort, and one single puzzle (even a large one) seemed a bit underwhelming. My solver set a high bar, and so I wanted to reach for it- so I decided on a Matchmaker puzzle. A few days later after picking types I had an outlandish idea. Why not attempt a Cipher Matchmaker, something that I couldn't find another example of anywhere? Would it be possible?

Yes.

After some initially planning, making and testing this took about 10-15 hours. If you're interested in a semi-detailed, spoiler filler breakdown of how I made this puzzle or a video walkthrough I made then feel free to check them out, or if you just want to solve the deciphered puzzles then those will be linked below. I would highly recommend giving the full puzzle a serious attempt before checking either of these, however.
