Best of 2021: Region Division

Here are our best Region Division puzzles of 2021 selected from the 52 web posts in this category based on FAVE votes, web comments, and tester comments. All of these puzzles are gathered in this PDF file.

One of our early weeks in 2021 focused on Araf puzzles and this “Oh Nine” Araf by Jeffrey Bardon showed that 2021 was going to be a good year for Region Division puzzles. Like some of our other best puzzles this year, this puzzle uses just the standard rules of a “classic” style, but it stretches those rules a bit in the visual presentation to lead to a very interesting looking puzzle as well as a very interesting solve.

While there is some debate about if Kuromasu (which uses rules similar to Cave and Four Winds) is a Region Division puzzle or a Shading puzzle, there is no debate that Swaroop Guggilam’s Kuromasu was one of the best 2021 puzzles based off the vote of our solvers. The X pattern in this grid leads to a nice interaction of clues.

The “checkered” variation of Fillomino led to another favorite puzzle in 2021, this one from Serkan Yürekli where the clues are under “Siege”.

This year had a close race between two Pentominous puzzles for the top Region Division spot. One of these puzzles, a Pentominous (Cipher) by Takeya Saikachi, was another gem from this constructor with a “Box in Box” theme.

Our best Region Division puzzle of the year goes to this unusual Pentominous by Elyot Grant that again obeys all the regular rules of the style but takes advantage of an unusual grid shape to make a “No Givens” puzzle that has a lot of different thinking to get to the one answer.
