Are you ready to meet the ultimate puzzle-cube challenge? Without the help of those familiar colored squares, players must solve this puzzle by twisting the cube to line up folds in the brain, making it a real head-spinner. To help you get in a cerebral mood, The Brain Cube is made of Kraton, a squishy material that feels eerily like a brain. Designed by Jason Freeny, an American sculptor known for his brilliantly original dissection of pop-culture toys, The Brain Cube exercises your visual perception, problem solving, concentration, and tactile perception skills. Cube away, cube genius!
