Your Kid’s Favourite Indoor playground & Party Place in Mississauga Balls of Fun is an indoor playground located in Mississauga. We have created the best kid-friendly ball gym that you can find! By creating two sections – one for babies and toddlers, and another for bigger kids, our indoor playground has become a go to place for children. Our gym consists of ball themes that help kids develop vital skills needed for playing and sports in general. Kids are free to run around and aim balls, balance on balls, bounce, and participate in our exciting obstacle games.
