Abstract: Systems and methods are provided herein for synchronizing content across multiple user devices. Content packets may be individually provided to user devices associated with a group. Each content packet may include a portion of content (e.g., media content) and a content index (e.g., an index that indicates a sequence by which the content packets are to be presented). The user device may begin to play the content packets according to the sequence. The user device may receive a particular content index identifying a particular content packet that occurs latest in the sequence and that has been received by all of the devices of the group. The user device may modify playback of the content packets based at least in part on the particular content index to synchronize playback of the content at the user device with respect to playback at the one or more devices.
