Abstract: A method includes outputting, on a GUI while a processor operates in a first operating state (OS), one or more spins of a reel set and determining whether a first running total of displayed symbols exceeds a respective first threshold of a first and/or second reward system. The method includes outputting a reward because the first running total exceeds a respective first threshold of the reward systems. The method includes transitioning the processor from operating in the first OS to a second OS, and outputting, on a GUI while the processor operates in the second OS, one or more spins of the reel set for the second OS. The method includes determining whether a second running total of displayed symbols exceeds a respective second threshold of the first and/or second reward system, and outputting a reward because the second running total exceeds a respective second threshold of the reward systems.
