Since children are the future, it is important that their playtime trains them to make powerful imaginary allies and appease our impending doll overlords over tea. Defend the fantastic world of tomorrow with today's Groupon: for $12, you get five open-play sessions at Jumpin' Jak's (up to a $25 value).

Jumpin' Jak's vibrant interior shelters 1- to 12-year-old chips off the old block from the elements while spurring imagination and exercise in themed wonderlands. The Goldrush Pass harnesses Western ambiance like a carriage pulled by tumbleweeds, and joyful laughter bounces off of slides and overhead bridges near a diminutive saloon. Relax as pintsize Cousteaus return tuckered from plumbing the depths of the ball pit or exploring the jungles of the Congo-themed play paradise. After lengthy sessions of sprinting along the multihued corridors and surveying the interconnected tree houses, Jumpin’ Jak's snack bar provides youngsters with provisions for refueling or fashioning regal capes out of fruit roll-ups.
