Shared Activities is the product name for a collection of features that allow Alexa skills to provide asynchronous multi-participant experiences, where the participant in multi-participant refers to an Alexa User engaging on an Alexa Enabled Device. These Shared Activities are long-lived social experiences such as games, recipes and fitness activities, where one user can share the activity with other users to engage them in it. For example, Joanna played a round in song quiz and scored 100 points. SongQuiz offered her to challenge someone to beat that score and Joanna challenged Bob. Another example is that, John just completed a workout and he can invite someone on fitbit skill to beat him.
