 “Jackbox Games” is a series of party games created by Jackbox Games, designed to be played in large groups, including in conjunction with streaming services like Twitch which provide means for audiences to participate. 

 Each installation contains five games that are designed to be played in large groups. The games in the series are for playing with friends, family, and streaming. 

 In order to play, one copy of the game is required. Other players only need to see the game screen and connect from their mobile devices or computers via a special website - jackbox.tv. 

 In most games, the maximum number of players is 8, but the rest can connect to the viewers and influence the course of the game.
