Abstract: A gaming machine platform includes a front display that is controllable to be opaque and display symbols during a first mode of operation, and controllable to be transparent to reveal a set of stepper motor driven reels during a second mode of operation. The front display may be part of larger display screen that displays peripheral reels that surround the front display. In one type of game, the front display displays a randomly selected array of symbols, and the peripheral reels display scatter symbols that are combinable with the front display symbols in a primary game to generate awards and possibly trigger a bonus game. When the bonus game is triggered, the front display becomes transparent to reveal the stepper driven reels for a bonus game. The bonus game may or may not use the peripheral reels.
