Best of 2018: Sudoku Puzzles

Here are our best Sudoku puzzles of 2018, selected from the 42 web posts in this category:

Visually distinctive puzzles were an important part of the top Sudoku from 2018. While posted in our last week of 2018, this Christmas Tree Sudoku by Thomas Snyder (that combines Sudoku with the popular Star Battle style) got a lot of FAVE votes in a rather short time.

While we have been avoiding “Pi” puzzles for a long time here — some of us assert there is a more fundamental mathematical constant around 6.283 — having some new editors involved on the web led to our first full week of “Pi” puzzles in March and some others later in the year. Two Pi sudoku stood out including this Consecutive Sudoku from guest contributor Fatih Kamer Anda.

Another prize goes out to an Arrow Sudoku from Murat Can Tonta.
