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.
