Puzzle Pack Vol. IV: Fillomino-fillia 2

November 13, 2012

At long last, the fourth puzzle pack, albeit several months later than I wanted. As this is a companion to the Fillomino-fillia 2 test and serves as its solution booklet, this pack is coauthored with mathgrant, who actually wrote more of the puzzles than I did.

If you did all of the Fillomino-fillia 2 puzzles on the test and preview series, don’t pass over this. You have only done 26 Fillominos in all. This pack has 56 total puzzles, so you’re not even half done.

Download the pack (PDF; 1863 KB)

This pack contains

  • The rules and a walkthrough for an example for Fillomino
  • 9 puzzles using the standard rules, including a large 20 by 36 brought to you by mathgrant
  • 10 puzzles representing all variations from Fillomino-fillia 1
  • 4 puzzles of each of the six variations from Fillomino-fillia 2: one easier 7 by 7, the two test puzzles, and the preview
  • 4 additional Fillomino-fillia 2 rejects: a Liar, a Snake, and two No-rectangles
  • 4 puzzles representing 3 new variations, which may appear on a tentative test for next year that might be called Fillomino-fillia 3
  • 4 chimera puzzles combining other variations in the pack
  • A fifth chimera puzzle: the FF2 version of last year’s Potpourri
  • Hints and solutions for all puzzles

Reporting of errors can be done by comments here or by email.

There will probably not even be progress on Volume V until 2013, as there are Mystery Hunt things to be done.

Puzzle 412 (Fillomino) [Snake]

This is a Fillomino Snake puzzle. A snake with a head and tail and unknown length must be drawn in the grid so that it contains all shaded cells. The snake does not touch itself, even at a point.

On a related note, it seems the WordPress thumbnail issue has fixed itself. That’s a relief.

Puzzle 398 (Fillomino) [Twins]

April 25, 2012

This is a Fillomino puzzle, with a twist. Each polyomino is the same size as exactly one other polyomino in the solution. In other words, each polyomino size is either used twice or not at all.

It occurred to me recently that 1s are probably my favorite Fillomino clues, amazingly enough. Hard to pick between 3s and 4s for second place though.
