<p>The present invention relates to a playing object (21) having a main surface (13, 14, 16) enclosing and provided around a center of gravity, said main surface being provided with protrusions (22) in a regular pattern around the center of gravity, where each protrusion has a protrusion surface distanced a distance from the main surface in a direction away from the center of gravity. The playing object may be a polyhedron and some of the protrusions may have a different appearance than the majority of protrusions.</p> |
