# Puzzle 120: Hochhausblöcke

Some more Hochhausblöcke. In other news, the 10×10×10 series on croco-puzzle continues, and I submitted a few puzzles to the excellent puzzlepicnic, including a Fences puzzle where I’m curious to know if people find the intended break-in, and a Yajilin.

Rules Place numbers from 1 to 4 in each cell so that each row and column of each 4×4-block contains all numbers 1 to 4. Circled numbers are valid skyscraper clues for the adjacent grid (for both adjacent grids in the central corners). Uncircled numbers are not valid skyscraper clues for the adjacent grid (for neither adjacent grid in the central corners).

# Puzzle 119: Skyscrapers (with parks)

Here’s a skyscrapers puzzle. This is from a batch of puzzles I recently made for a series on croco-puzzle, consisting of 10 puzzles on 10×10 grids. I thought it was a nice opportunity to try my hands at making a large skyscraper puzzle, after some failed attempts in the past. The difficulty turned out such that it didn’t really fit with the rest of the series, so here you go.

Buildings of size 1-9 and one park (gap, invisible) per row and column.

# Puzzles 114-118: Slalom / Slant

A few more Slaloms. Nothing new compared to the previous few, and not as pretty, but maybe they help getting at the logic?

# Puzzle 111: Slalom / Slant

Here’s a Slalom puzzle. (Which is what croco-puzzle calls them and what I used previously, though I’m partial to Slant by now.)

# Puzzle 110: Greater Wall

The next round of the Puzzle GP takes place next weekend, with the Dutch round authored by Bram de Laat. The instructions are out; it turns out Maxi Loop is one of the types (see Puzzle 91 and Puzzle 109), so we’ve got that done. One of the less familiar types is Greater Wall, compare Bram’s set for the Polish championships. The presentation has been much improved, with explicit placeholders. Here’s one.

Rules Shade some cells to form a wall that is connected by edge and doesn’t contain any 2×2-square. Where given, clues outside indicate all connected blocks of shaded cells in the corresponding row or column, in the correct order. Relations between two placeholders apply to the lengths of the corresponding blocks.
