A rail (12) borders the playing surface to keep the puck on the playing surface. The aim of each player is to strike the puck with a bat into the opponent's goal, while blocking the puck from entering his/her own goal. The extremely light weight puck, which has a diameter of 64 mm and a thickness of 1 mm, has the shape of an extremely shallow, inverted cone with the side (18) having an angle of 0.3 degree. When the puck is struck by a bat, air rushing against the underside of the cone-shaped puck lifts the puck completely off the playing surface, such that the puck glides on a thin cushion of air. Because the puck travels across the playing surface without friction against the surface, the puck can maintain very high speeds to greatly challenge the dexterity and reaction of the players as they try to strike or block the fast moving puck. ## Claims ### Claim 1 A game, comprising: a horizontal surface; a thin puck having a bottom surface that may be juxtaposed with said horizontal surface, and adapted for being given a sufficient velocity across said horizontal surface that air rushing against said bottom surface lifts said puck completely off said horizontal surface, whereby said puck travels on a thin cushion of air across said horizontal surface at high speed without frictional engagement between said horizontal surface and said puck; a bat for striking said puck; a raised border forming a perimeter around said horizontal surface for containing said puck within said horizontal surface; and a goal disposed above said horizontal surface within the perimeter formed by said raised border, said goal being adapted for catching said puck between said goal and said horizontal surface if said puck enters into a space between said goal and said horizontal surface. ### Claim 2 (depends on 1) The game of claim 1 wherein said bat comprises a generally flat disc having a thickness greater than said thickness of said puck. ### Claim 3 (depends on 2) The game of claim 2 wherein said goal comprises a horizontal flat plate spaced slightly above said horizontal surface, said horizontal flat plate being upwardly angled towards a central region of said horizontal surface for receiving and catching said puck. ### Claim 4 (depends on 3) The game of claim 3 wherein said goal is generally rectangular in shape. ### Claim 5 (depends on 3) The game of claim 3 wherein said puck comprises a round disc. ### Claim 6 (depends on 1) The game of claim 1 wherein said puck comprises a round disc. ### Claim 7 (depends on 6) The game of claim 6 wherein said puck comprises a plate having the bottom surface thereof formed in a convex conical shape that has an angle of between 0.1 degree and 3.0 degrees with a plane parallel to said puck. ### Claim 8 (depends on 6) The game of claim 6 wherein said puck comprises a plate having the bottom surface thereof formed as a shallow "W" radial sectional shape with a central concavity surrounded by an upwardly angled flange extending from the edge of said concavity to the perimeter of said puck, the radial portion of said upwardly angled flange making an angle of between 0.2 degree and 10 degrees with a plane parallel to said puck. ### Claim 9 (depends on 6) The game of claim 6 wherein said puck comprises a plate having the bottom surface thereof formed as an inverted dome with an upturned shallow arc cross sectional shape. ### Claim 10 (depends on 1) The game of claim 1 wherein said horizontal surface is flat and smooth and covered with a glassy smooth liner. ### Claim 11 (depends on 1) The game of claim 1 wherein said puck comprises a plate having the bottom surface thereof formed in a convex conical shape that has an angle of between 0.1 degree and 3.0 degrees with a plane parallel to said puck. ### Claim 12 (depends on 1) The game of claim 1 wherein said puck comprises a plate having the bottom surface thereof formed as a shallow "W" radial sectional shape with a central concavity surrounded by an upwardly angled flange extending from the edge of said concavity to the perimeter of said puck, the radial portion of said upwardly angled flange making an angle of between 0.2 degree and 10 degrees with a plane parallel to said puck. ### Claim 13 (depends on 1) The game of claim 1 wherein said puck comprises a plate having the bottom surface thereof formed as an inverted dome with an upturned shallow arc cross sectional shape. ### Claim 14 (depends on 1) The game of claim 1 wherein said goal comprises a horizontal flat plate spaced slightly above said horizontal surface, said horizontal flat plate being upwardly angled towards a central region of said horizontal surface for receiving and catching said puck. ### Claim 15 (depends on 14) The game of claim 14 wherein said goal is generally rectangular in shape.
