Abstract: A gaming server can host a gaming session involving multiple players utilizing separate gaming devices. To ensure consistency across devices, the gaming server receives player-specific game data from each device then sends updated game state data to the gaming devices. Each gaming device includes a circular buffer that can contain up to a determined amount of recent game state data. If a device is to provide an instant replay, the devices can pull the state data from the circular buffer and cause the game replay to be rendered according to the timeline of the buffered game state data. Once the replay is finished, the game session resumes and new game state data is stored to the circular buffer. The gaming server can also store the game state data such that after the session the state data can be downloaded and a full replay rendered.
