Slot machines can be affected by power surges or outages. In the event of a power surge, a machine may malfunction, potentially disrupting gameplay or affecting the integrity of the game's software. An outage can lead to machine resets, and players may lose their game progress or winnings associated with that session. However, modern slot machines are designed with safety features to protect against such events, and casinos typically have backup systems to minimize disruptions. After a power interruption, machines usually require a reboot, and any credits or progress are often restored to ensure fairness and compliance with regulations.
