Abstract
An electronic slot machine (10) and method of use which allows a player to completely replace up to all of the initial symbols displayed after the first draw in order to create, improve or even lose a winning combination. In its preferred form, the electronic slot machine of the present invention features a video monitor (10) with a plurality of separate symbol display boxes (32) arrayed in rows and columns. When the machine is activated, one or more random numbers are generated in the slot machine's microprocessor (15) to determine which symbols are to be displayed in each of the symbol display boxes. If a suitable winning combination is not formed with the initial symbols, the player is given opportunities to select up to all of the symbol display boxes for replacement.
