Roll the wobbly weighted ball at just the right angle to make it curve smoothly past the two obstacles. Kids will need a lot of skill and perfect precision if they want to hit the pin! Start with the 10 included challenges, rolling between and around the obstacles in a variety of unique arrangements. Then, get creative and invent your own challenges! Roll around the legs of the kitchen table, between stacks of books, past your sleeping cat… It’s all about using the lopsided weight of the ball to your advantage to make it do whatever you can imagine!
