push out duels
when you streaming with a friend or vip sub.
and they are also streamers that you can do a duel against each other.
but more simply games that are available in twitch.
so that also the viewer en followers from both streamers. the other streamer can see playing.
its good for everyone and alot of fun.
as i streamer you can get more viewers or followers and new friends
as follower/viewer you can deside with one of the 2 streamer was the best in that game. and so they can see a new streamer live in action.
