Apparatus for conducting sports and games on a slippery solid playing area surface comprises one or more doughnut-shaped streamlined discs which include a self-contained propulsion device. Each disc optionally carries an operator and includes around the perimeter thereof a resilient collision bumper. The surface of the playing area comprises a slippery upper layer and a solid underlayer. Each disc, while being supported on the surface upper layer in sliding relationship, is slidingly moved over the surface upper layer by propulsion devices acting relative to the underlayer. Such propulsion can be generated, for example, by electromagnets, motors, jets and the like. Various playing area surface compositions are also disclosed.
