Link to original post : Puzzle 40 / Fillomino [Samurai]

Yeah, and there’s this. chaotic_iak rejected this variant for his February sequence in order to get consistent 7×7 dimensions, so I made one. It’s been about a month. I have no idea why I procrastinated posting it until now. This is a Samurai Fillomino, which means each grid satisfies the constraints on its own. Write [...]

Link to original post : Puzzle 41 / Slitherlink [Clones]

I survived midterms. This is a Slitherlink mutant. Draw a loop through adjacent vertices that cannot intersect itself. Each number indicates how many of the four edges around it are drawn. In addition, each pair of colored squares in corresponding positions (e.g. R1C1 and R6C6, R2C8 and R7C3) must have an equal number of edges [...]

Link to original post : Rankk Solving Statistics

Funny, I go on a trip to Penghu followed by a four-day science camp and also get dragged into drawing classes and some sort of movie advising joint, and this is what I decide to blog about. Since it’s summer, I went back to Rankk and solved stuff. This is lots of fun if you’re […]

Link to original post : Puzzle 42 / Fillomino [Greater-Than]

Oops, I forgot the “puzzles” category was semi-reserved for puzzles I constructed/wrote, because among other things an LMI bot is following it. Anyway, if this makes up for anything, I have a puzzle that I’ve procrastinated posting for very, very long. This is a Fillomino puzzle. Inequality signs in the grid must be satisfied by […]

Link to original post : Puzzle 43 / Fillomino [Nonrectangular + Walls]

I’m extremely satisfied — a little incredulous, in fact — with how this puzzle came out. chaotic_iak labels it the “most ridiculous fillomino ever in history”. Apparently, it’s rather tricky. ETA: Journalistic responsibility compels me to mention that chaotic_iak also added, “might be beaten later”. Oops? This is a Fillomino combining the Nonrectangular (polyominoes can’t […]

Link to original post : Puzzle 44 / ???

ETA 11/19 7:23 AM UTC+8: Fixed some transcription errors on right: R4C17 is D instead of N, and R15C17 is G instead of E. Neither change should greatly impact solvability. Thanks to ksun for pointing out an error. Logic puzzles are easy to construct if one doesn’t have some specific pattern or theme in mind. […]

Link to original post : Puzzle 45 / Fillomino [No-Path]

As requested, a puzzle post! Straight from the WTF-variant department. Quite hard. This is a Fillomino, with the additional constraint that for each polyomino, there must not exist a path (i.e. a sequence of cells, each orthogonally adjacent to the next) that includes each of the polyomino’s cells exactly once (and does not include cells […]
