All of these discs are rotatable with respect to one another about a common axis. A Velcro ring is provided on the inner disc and includes a plurality of Velcro triangles which may be positioned adjacent the numbers on the inner disc. The base, outer, and inner disc each include one ring which includes a plurality of ring segments having numbers thereon. The middle disc includes three concentric rings, each of which is broken into ring segments having numbers thereon. The method of the present invention comprises selecting an initial base set of numbers at random, positioning the Velcro arrows adjacent those numbers on the inner disc, and recording the columns of numbers which appear on the middle disc located radially outwardly from each of the arrows positioned on the inner disc. The columns of numbers are recorded in a matrix, and the ultimate selection of numbers is accomplished by selecting the rows of numbers within the matrix.</p> |
