Balls are held in place by a hard foam pad in the centre. Balls that are out of place don't actually move away from the hole, and it takes time to move them so far that putting them back in place has become a chore. Then I don't feel comfortable moving them around that central block of foam. I expected the balls to "snap" into the holes and then move freely in the frame, but they don't. Since I didn't find it funny, I guess neither did my son, so I'm sending it back instead of putting it in my stocking.
