Streaming service Twitch introduced the first game – Twitch Sings. It was developed jointly with Harmonix, which is known from the Rock Band and Guitar Hero series. The game is not supported in Ukraine, Russia and Korea due to restrictions in licenses.
Twitch Sings is built on interaction with the audience. They can support the performer with applause, vote for the compositions that the streamer will sing, and give various tasks.
The game is free. You can download it here. In the future, Twitch has promised to add microtransactions and release paid add-ons.
