2. Jenga There is a reason that several bars and coffee shops have sets of Jenga in house for people to play while they hang. It’s fun at any age—and it’s downright awesome adult fun. These days you can choose from the original version, Jenga Giant or from XXL blocks that stack up to 8 feet high! No matter how or where you play it, you know you’re going to freak out when someone knocks over the towel of blocks. Your inner kid will laugh while your strategic adult brain is plotting your next move.
