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.
You can check your solution and solve online here.
Here’s a puzzle that I made as a Christmas present.
Rules Place the given set of dominoes in the marked domino tiles. Whenever two dominoes touch by an edge, the adjacent numbers must be the same. Clues outside the grid are skyscraper clues: They indicate the number of visible skyscrapers when looking along the corresponding row or column from that point, where each number represents a skyscraper of that height. Skyscrapers are blocked from view by those of greater or equal height.
Here’s a Statue Park puzzle, with a full set of pentominoes. I made this one on the train back from the WPC in Senec, I still plan to post some thoughts on that some time.
In other news, I’ve been writing some puzzle sets for Nibbl (Android, iPhone). It’s an app that works as a solving interface and marketplace for handmade puzzles. See also Rohan’s announcement from earlier this year; the interface has been improved quite a bit since then. If you use my referral code ROBR9402 (or someone else’s), you’ll start with 100 credits, with which you should buy some of my star battle or skyscraper puzzles which came out pretty well.
I won’t stop posting here, though, don’t worry!
Rules Place a full set of twelve pentominoes in the grid. Different pentominoes must not touch along an edge; they may touch diagonally. Black circles must be part of pentominoes, white circles must not. All cells that are not part of the pentominoes must be connected by edge.
We continue with more Illumination.
Edit Fixed a clue.
Here’s a Divisor Sudoku. I made this one for the 24h review series on croco earlier this year, but ended up making a second easier one. Please excuse the lazy rendering.
Rules Standard Sudoku rules. In addition, the givens indicate a divisor of the corresponding two-digit number (left-right or up-down).
A companion skyscrapers puzzle to puzzle 119. This was the first one I made, 119 was meant to be easier, but still too hard.
Buildings of size 1-9 and one park (gap, invisible) per row and column.
EDIT fixed shifted clues along the top.
Have a Summon. If you’ve already figured out the kind of argument this one is built around it’s not that difficult.
