A flying disc is provided that comprises a thin central plate 20 with an outer annular rim 30 formed with convex curves. It has an outer rounded corner 62 and a lower rounded corner 63 joined by a convex curve 71. An inside rim 80 is preferably substantially vertical. The curve joining the lowest part of the rim to the inside rim may be formed so that its radius of curvature decreases towards the inside rim. |
