Abstract
Abstract A slot machine with at least three coaxially disposed wheels having a plurality of playing symbols on the peripheries thereof, wherein a plurality of columns of windows, one column for each window, are disposed in front of the wheels to enable viewing of a preselected number of symbols of each wheel and to define a plurality of win-lines for play of the slot machine. The windows of the plural columns are disposed in a triangular configuration, with one end window column permitting viewing of only one symbol and with window columns of adjacent wheels revealing greater numbers of symbols in direct proportion to the distance from the one end column, the wheel associated with the one end window column being the last to stop rotating during play of the slot machine.
