Puzzle 151: Skyscraper-Nurikabe

We continue with the regular puzzle-a-month-on-the-first-of. Here’s a Skyscraper-Nurikabe, a practice puzzle for the upcoming Indian GP.

Rules Solve as a regular Nurikabe. Additionally, some skyscraper clues are given outside the grid. For these, consider the blocks of adjacent shaded cells within the corresponding row as skyscrapers with height equal to the number of cells in the block.

Or check the instruction booklet which includes an example.

You can solve online (of sorts) and check your code here.

Puzzle 149: Skyscrapers²

The WPC 2017 in Bengaluru is over. Here’s a puzzle from my very thin set of preparation puzzles. It’s from a round with original types that applied the same set of rules “twice over” in a sense.

Rules Solve the grid as a regular skyscrapers puzzle, digits 1 through 5. In addition, small clues in the outer corners are skyscraper clues for the regular skyscraper clues along the outside. These 20 regular syscrapers clues are part of the solution.

For example, the regular skyscraper clues along the left side could be something like 1,3,5,2,2 to satisfy the second-level 3 clue in the top left corner.

Or see the rules of Round 20: Puzzle Fusion in the WPC instruction booklet, available at the WPC page. You can find an example there, too.

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 107, 108: Hochhausblöcke

To make it a full two weeks of post-LM posts, here are two more Hochhausblöcke. One with the maximal number of givens, one with the minimal number. (There are some more of each, but these are the nicer ones. The minimal one requires a well-placed deep case distinction, or I do at least.)

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).
