<p>A gaming system having a ball (10) of uniform spherical outer surface (14) wherein the density of the ball (10) is not uniform about its centre (16) so that the centre of gravity of the ball (10) is offset from a centre of curvature of the ball (16), thus providing an asymmetrically balanced spherical ball (10). The ball (10) may be solid or, alternatively, may comprise a hollow rigid outer shell (14). The gaming system further comprising a playing surface (120) that has a light source (100) positioned directly above such a surface (120), wherein the light source (100) has a support frame (130) for receiving a projection template (150) and for restraining that template (150) between the playing surface (120) and the light source (100) so as to porjet a pre-determinated pattern from the template (150) onto the playing surface (120) to vary the visible indicia on the playing surface dependent on the pattern formed in such template.</p> |
