Puzzles #116 & #117 - Puzzle Chimera (Doppelblock, Skyscrapers)

I hadn't really tried to construct a chimera before, or a puzzle that works in multiple different genres simultaneously. Doppelblock is a type that I'm trying to understand better, and it pairs well with Skyscrapers. Neither puzzle here is that difficult, but hey- I'm trying to make puzzles I find interesting.

Puzzle #115 - By the Dozen (Doppelblock)

I decided to try to make a larger Doppelblock today. After a few constructing dead ends, I managed to find this one.
For the interested solvers, it turns out that if you change the 4 to a 5, then the column 1 clue is unnecessary. However, I wasn't able to find a solution without casebashing on that version, and the only easy fix gave away a lot more information, so I tried a 4 instead.

Puzzle #113 - Another Accidental Variant (Aquarium)

So... I misunderstood the rules of Aquarium slightly. There are 2 main variations on the rules relating to water level within regions. The simpler version, and the more common one is that the water level must be constant within a given region regardless of any barriers between columns. The less common version that's still treated as "normal" is that the water level in a region can be at different heights, as long as there are separate "pools".

However, I thought that it meant that water would only move sideways and down, never back up to "equalize" as it's supposed to. So this puzzle will not have a correct answer check, but if the only error thrown is about row 4, then you're good.

tl;dr Variant puzzle where water must move across and down only. Water level can be unequal as long as all possible across and down "spreads" are made.

Puzzle #112 - Waterwheel (Aquarium)

Aquarium is a type that was added to puzz.link fairly recently, and a type that had a little discussion on the Discord server. So I tried my hand at making a few, partially because it's a type I want to include in a future competition set (hint, hint). This was the last one I ended up making, and tomorrow I'll post the first one.

Puzzle #111 - Shining Light (Akari)

While working my way through the puzz.link database I came across a very, very large Akari puzzle. This puzzle was inspired by a deduction from that puzzle that would have worked, had one number been one larger.

Update: fixed an ambiguity from the original version of the puzzle.

Puzzle #110 - Everything Must Go (Masyu)

A common Masyu variant is to require all cells in the grid to be part of the loop. So I decided to use that variant and make an anti-symmetric Masyu puzzle, because I'd sort of tried that constraint before without success and this felt like an easier way.

Puzzle #109 - Tetromino Tower (Masyu)

Another day, another Masyu puzzle. As my entry for Logic Showcase 12, all pearls had to come in groups of 4 or 5. Originally, I tried making a puzzle from just the 12 pentominos once each, but had no success in finding a good arrangement. Then I tried a 10x10 with just S tetrominos with similar failings, but that puzzle turned into this once I added some other pieces and enlarged the grid. Unfortunately symmetry still broke and I couldn't fix it, but this puzzle has a very nice flow to it and placed 6th of 13.

Puzzle #108 - White Snake (Masyu)

This is a Masyu puzzle. Probably easier than the last two. Sorry about the delay between posts, had to hold off on posting my Logic Showcase 12 entry.
