ABSTRACT:
The invention is an improved yo-yo that has a rotatable, outwardly-facing roller on each of its two sides. Each roller has an outwardly-facing opening that is sized and shaped to facilitate a non-slip engagement between a finger and the roller. The opening also provides access to an O-ring that functions to secure the roller to the yo-yo.
