Here are our best Region Division puzzles of 2019, selected from the 45 web posts in this category based on your FAVE votes:

We had two favorite Pentominous (Borders) puzzles. The first, from Murat Can Tonta, was an amazingly beautiful 12-clue puzzle with each pentomino letter appearing in “Alphabetical Order” in the grid. That this solves uniquely as a Pentominous puzzle is a true grandmaster’s touch.

The other Pentominous (Borders) that was a best of 2019 was from Grant Fikes, and had a more involved logical solve that went around the grid.

Guest contributor Michael Tang brought our favorite Cave puzzle of 2019 with another fun logical solving theme to discover.

We had a few surprises in store last year, including a hidden January connection to the 2019 MIT Mystery Hunt when some Fillomino (Cipher) puzzles by Tim Marsden (anagrams to Mastermind) were posted in January. These puzzles were actually by Dan Katz, and linked as a final step in another puzzle, Connect Four, from that Hunt. This hardest Cipher puzzle, with full top and bottom rows, was a favorite of 2019.

Overall, our best region division puzzle of 2019 went to John Bulten’s Fillomino with some trademark Bulten-Aha moments to go from a seemingly impossible puzzle to something with a logical path.
