This puzzle ball is a hands-on game that can improve basic problem-solving skills, concentration and color-sensitivity for kids on the autism spectrum. It has 11 balls in different colors to be matched with their corresponding colored rings on the outer shell. The one extra hole can be used to shift the balls until the user finds the right hole for each color. It's easy to store due to its lightweight, compact design and can be easily held and twisted to move the separate pieces around the ball. Great for school, long car rides, playgrounds, and more!
