When thinking of head-to-head competitions, the Central Library’s quiet atmosphere may not seem like the obvious choice. Unless, of course, it’s part of the library’s annual Arlington Puzzle Festival.

This Saturday, November 3, the festival returns for a second year of words, logic, numbers and thinking. The mind games run from 8:30 a.m.-4:30 p.m. in the Central Library’s (1015 N. Quincy Street) auditorium.

Crossword puzzles are provided by New York Times puzzlemaster Will Shortz and sudoku puzzles will be provided by U.S. and world champion sudoku solver Thomas Snyder.

The event is free for Friends of the Arlington Public Library members. A donation is suggested for non-members.

There will be speakers throughout the day, including professional crossword puzzle writer Matt Gaffney, the crossword tournament begins at 10:00 a.m. and the sudoku tournament begins at 1:30 p.m. The full schedule of activities throughout the day is listed online.

Registration for the crossword and sudoku competitions is available online, and will also be available at the door on a first come, first served basis.
