Cloud gaming operates by streaming video games to a user's device over the internet rather than requiring local installations, which allows for play across various platforms. The game's graphics and processing are handled on powerful remote servers, and the game's output is sent to the player's device in real-time, while the player's inputs are transmitted back to the server. This model enables instant access to high-quality gaming experiences without the need for dedicated hardware. It democratizes access to gaming, allowing players to enjoy advanced titles on modest devices.
