A washer toss game apparatus is disclosed comprising: 1) a planar member having a hole through a central portion thereof; and, 2) an upright support member which has three lateral grooves through a central portion thereof, each which closely fits an edge of the planar member. The planar member accordingly may be positioned at three different levels of inclination. The planar member is additionally provided with a non-slip resilient planar strip on one side thereof, so that when this side is positioned upwardly the washers are more easily tossed and maintained on the planar surface. By increasing the angle of inclination of the planar member and turning the slippery side upwards the difficulty of scoring can be increased. Each player alternatively tosses four washers in a round. All washers of one player which are closer to the hole than any of the washers of the other player score points. Three points are awarded for a washer passing through the hole; one point for other scoring washers. Additional rounds are played until one side achieves and wins with 21 points.
