The Friends and Staff of the Cos Cob Library present a workshop with National Sudoku Champion, Nate Tsyrulnik, who will unravel the mysteries of Sudoku. Join us in the Community room and learn the techniques of these puzzles. Ask questions, and find out how to master this fun game. It's brain food for all today! Light refreshments will also be served! For questions call the Cos Cob Library at 203-622-6883 or email Anushya Makam at amakam6@gmail.com
