Stream Games

Stream Games is a set of mini games that Twitch Streamers can play with their viewers' interaction

As a Streamer, you can connect Stream Games to chat
of your channel and allow your viewers to participate in mini-games to
earn points.

You can enter the commands that the bot of your channel uses to add
points to the viewers, if they use any. That way, your viewers will win
points when winning the games.

Multiplayer and interaction only works through one channel chat from
Twitch (twitch.tv)
