Rainbow ball spin

The object in the image is a Cayro Rainbow Ball puzzle, a type of brain teaser and fidget toy. This puzzle is a ball with a number of holes (typically 12) and colorful small balls inside (typically 11). A sponge mechanism in the center allows the internal balls to slide from one slot to the next when pressed. The objective is to scramble the colored balls and then figure out how to get them all back into their matching colored slots in the corresponding holes. This engaging 3D puzzle helps develop problem-solving skills, spatial reasoning, and hand-eye coordination, making it suitable for both children (usually aged 6+) and adults.
