The Rotating Magic Bean Puzzle from Puzzle Ball is a new way to play! Turn the beads, slide them across, and even swap sides! This innovative puzzle is quite the challenge. Four O-shaped concave holes are carefully designed, and each hole has 8 balls. The position of the ball can be replaced by pushing the middle horizontal bar. Both sides of the colorful ball rotating toy are designed with protruding particles, which can increase the friction with the hand, and also can massage children's hands. Help your child develop hand eye coordination and grip. How to play: 1. Randomly scramble the little magic bean top ball. 2. Move the middle horizontal axis to replace the required beads in different O-shaped grooves. 3. Through memory and spatial imagination, the beads in the 4 grooves can be matched at the fastest speed.
