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]

October 23, 2012

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. The remaining spaces must be divided into polyominoes satisfying the usual Fillomino rules. The snake may touch polyominoes of the same size as itself.

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

Fillomino-fillia 2

October 22, 2012

After almost a year and a half, I’m finally (co)writing another LMI test. Fillomino-Fillia 2 will be held at Logic Masters India on the weekend of October 27th. This is a sequel to last year’s Fillomino-fillia test, which was a set of Fillomino and variations that I cowrote with mathgrant. This year, mathgrant and I are bringing you even more Fillomino puzzles.

The format is similar to last year: 4 classic puzzles, 6 new variations with 2 puzzles apiece, and a “Best of Fillomino-fillia 1” section with 2 puzzles, representing 2 variations from last year’s test. As always with LMI tests, you can begin the test at any time between (on a US time zone) late Friday and late Monday, and once you start you’ll have 2 hours to solve as many of the 18 puzzles as you can.

Like last year, mathgrant and I will each post a four puzzle preview series, which will allow you to get familiar with the new variations on this year’s test. Each of us will be posting one per day over this week, with the last going up shortly before the test can be begun.

The delays in getting this test finished and scheduled at LMI are the reason for there being no pack release for so long. I had intended a post-mortem booklet with commentary, rejects, and plenty of extras to be puzzle pack volume 4 since forever ago, but we kept having to push the date of this test back. Anyways, that pack will probably be released within a week of the test being over. Volume 5 may have to wait until after Mystery Hunt is done; we’ll see.
