When a special symbol appears during play of the gaming machine game, the
secondary game is initiated. At initiation, a bonus prize is determined
by the secondary game microcontroller by consulting a bonus game paytable
stored therein where each bonus prize corresponds to a bonus spot on the
secondary game. A multi-ended pointer of the secondary game spins around
the field of bonus spots and the player is prompted to select which end
of the pointer is active. Upon selection of the end--e.g. blue or
green--a microcontroller operating the spinner calculates the point at
which the spinner will cease to spin so that the selected pointed end is
pointing toward the selected bonus prize. The player is given the
illusion that he or she controls which bonus prize is won since the green
side of the pointer will point to a different bonus prize than the blue
side.
