"Catch That Ghost!" — a MoMath puzzle hunt for families


In this family-friendly puzzle event, teams of children and their grownups will explore MoMath and midtown Manhattan on a locations-based adventure, using their wits and mathematical knowledge to solve a mystery!  This puzzle hunt is designed to be played anytime during staffed checkpoint hours and solvable in approximately three hours by school-age children.

Suggested team size of three to six players.  Each player must purchase a ticket, and the number of teams is limited due to event capacity.  Team captains, please register early!
