Marbles: The Brain Store, Aurora

The human brain keeps growing until around the age of 10—but why stop there? Marbles: The Brain Store stocks its play matter with handpicked, expert-tested toys, games, and activities designed to both engage young minds and boost brains of all ages. Along with creative kids' toys, Marbles carries products that help aging folks stave off memory loss, help children with ADHD focus, or simply help everyone work out their brains' five key abilities—critical thinking, word skills, visual perception, coordination, and memory. Whether in store or online, the selection includes winners of accolades such as the Mensa Select Award or the National Parenting Seal. And Marbles has even built its own line of brain-boosting toys and games conceived specifically to build the complex array of smushy puzzle pieces within each of our skulls.
