Yackle Ball starts about 5-6 years old for boys and 7-8 for girls. We also have Yackle Ball Jr. for the little ones. Currently, there are multiple games for playing alone, with friends, right up to a full team sport that is being introduced into schools and even the colleges are playing. The ball and games combined create a wonderful energetic outdoor activity the whole family can play. So whether your family is large or small, everyone can get in on the action.
