For the first Play Roly, all you’ll need is a device to play the Play Roly videos, a ball to make Roly, and a marker pen. Roly can be any size ball or anything that rolls!   Other things you’ll need as you progress through the Play Roly videos include a blank book or paper, coloring crayons or pencils, and a mini-Roly-ball (about 1” in diameter).
