6 Bits in Extensions
Use of Bits on Twitch is governed by the Bits Acceptable Use Policy and the following policies:
6.1 Bits may be used within your Extension:
6.1.1 To activate an experience for the broadcaster and/or the community. For example, the community feeding a virtual pet with Bits that continues to grow; a digital popcorn machine teeters on the verge of exploding when the community uses Bits.
6.1.2 To unlock a digital consumable experience on Twitch. For example, Bits are exchanged for a special avatar within an Extension game.
6.1.3 To enrich or enhance gameplay in a free-to-play game. For example, Bits may be used to unlock otherwise unavailable levels of gameplay (i.e., unavailable due to timers, energy systems, or other throttling mechanics), gameplay lives, gameplay avatars or character attributes, gameplay speeds, and social features for interacting with others in the Twitch community.
6.1.4 For voting activities in your Extension, such as allowing viewers to use Bits to show support for a desired outcome made available through a poll or voting mechanic.
6.2 Bits may not be used within your Extension:
6.2.1 To obtain access to a pay-to-play game.
6.2.2 To allow an end user to use Bits to play a specific musical track or audio-visual work. (e.g., jukebox-like functionality).
6.2.3 If your Extension contains gambling activities that provide a reward with a monetary value (e.g., a slot-machine game that allows winners to obtain a downloadable code to redeem a game).
6.2.4 Where Bits can be exchanged for loot boxes with unknown items that are determined randomly or by chance.
6.2.5 To provide the end user with an entry into a sweepstakes or contest, whether through a token or otherwise. For example, do not design a scenario in which a viewer can use Bits to obtain a gem that will allow the user to participate in a sweepstakes to win a free flight to the DOTA championships.
6.2.6 For engaging in “wagering” or “betting,” on gameplay events, contests of chance, or other outcomes beyond the end user’s control, to win additional Items or rewards. For example, do not suggest that if a viewer spends Bits on the outcome of a Fortnite match, and the streamer prevails, any viewer that presented Bits will obtain game codes.
6.2.7 If your Extension provides VOIP-related functionality.
6.2.8 Where Bits can be exchanged for items or experiences specified by broadcasters or end users, rather than specified by the Extension itself (e.g., utilizing a blank free-form text field, rather than a pre-populated drop-down menu).
6.3 You may establish the amount of Bits necessary for the exchange of permitted items or experiences in your Extension. Twitch reserves the right to require adjustments.
6.4 You may not describe the use of Bits in Extensions as “cheering,” which is a different Twitch feature.
6.5 You may not describe the use of Bits in Extensions as a “donation” or ”support” in the financial sense for the broadcaster, “money transmission,” “purchase,” “spend,” “buy,” “insert” (such as likening Bits to quarters), or other similar description.
