## Abstract

A playing wheel rotatably secured on a base fixed on a fixture of a playground includes a solid spoke portion diverging radially outwardly from a central hub portion of the playing wheel and a plurality of finger slots cut out in a periphery portion of the wheel adjacent to an outermost rim portion of the wheel to prevent injury to a child's fingers or hand as protected by the solid spoke portion of the wheel by eliminating the big openings easily entrapping a child's hand as formed in the spoke portion of a conventional playing wheel.
