While we’re all waiting for the WPC instructions, here’s a Checkered Fillomino that Silke Berendes made for the Puzzle GP finals. The organizers chose her Yajilin instead, so now you can solve it here. Thanks!
This was another type on the mixed round. It seems that “knapp daneben” almost works better for checkered fillominos than for the plain ones.
Rules Add or subtract 1 from each clue, then solve as a standard Checkered Fillomino.
Here’s a Checkered Fillomino, flowery theme.
One Minesweeper puzzle (with an unknown number of mines). The kind of puzzle that just feels too trivial when constructing, although in the end I think it’s quite ok.
One Pentominous, with the obvious PL theme.
Finally a small an tricky Checkered Fillomino.
Two more Checkered Fillominos. I made a bunch of them for the 24 hours that take place in Budapest this weekend. These here use some different logic. The first one turned out to have an easier break-in that circumvents what I had in mind, but maybe the similarities help as a hint?
The German qualification is through. The puzzles will be available there again sooner or later, maybe I’ll post my contribution to the set here later. Here’s a somewhat trickier Checkered Fillomino that didn’t make it. I’m not sure it’s right to tag it as hard, that depends a lot on how well you know the type.
This variation was introduced by Nikolai Beluhov at Puzzled by Titles, see the authoritative rules and two very tricky puzzles: Fillomino 6: Checkered, Fillomino 8: Checkered. Here’s something that’s hopefully both correct and a little more approachable.
Rules (brief): Solve as a standard Fillomino, and shade some resulting polyominoes, such that no two shaded or unshaded polyominoes share an edge.
