Fillomino and Cave are the two major Region Division styles we have here at GMPuzzles, and 2013 saw 39 puzzles across this space. The favorites here span the calendar year.

Standard Fillominoes formed many of your most favorite puzzles. While it was one of the more recent puzzles, Grant’s 28-dice opus #8 received a good ratio of fave votes to solves.

In July, after Palmer debuted as a contributor here, his seventh puzzle with an Antisymmetric Ones theme received your votes.

And perhaps because of the challenge (our hard puzzles seem to be more favored than our easier ones), Squeeze Play from March also made the final cut.

These two cave puzzles slightly edged out Fillomino at the very top this year though. Almost Perfect 10? from our initial release of Cave puzzles got high marks.

But the Region Division Puzzle with the most votes was this Cave (Product) variation from early April. We’ll certainly see if we can provide more of this Product variety in the future.

You’ll find all these puzzles grouped in this PDF.
