You can do that for as long as you can cup the small ball and push it down the lane. No finger holes needed. Even school aged children can roll the ball down the lane. Obviously, the faster, the better, but they CAN do it, just like "old people" can still bowl.

You get 3 much smaller & lighter balls per turn. The pins are considerably thinner, but fairly tight together. It's harder in some ways and easier in others.

Jus' sayin'.
