Abstract
The invention is an improved yo-yo that has two side units and a string-formed response system incorporated into each side unit. In its most basic form, the response system employs a string that is threaded through spaced-apart apertures in a side unit to form at least one tether engagement pad. The pad may be contacted by the yo-yo's tether in order to cause a return of the yo-yo to a user's hand.

- wherein said first side unit has a tether-facing surface and a plurality of spaced-apart apertures;
- and
- a string threaded through a plurality of said apertures in a manner whereby said string forms a plurality of tether engagement pads located on said tether-facing surface and wherein when said yo-yo is sleeping, said pads are capable of facilitating a return of said yo-yo to a user's hand.
