A Twitch feature that lets game developers grant in-game rewards to viewers who watch participating channels streaming their game. Twitch tracks watch time and selected viewer actions; once a viewer meets a campaign's rule, they claim the Drop on Twitch and the reward is delivered in the game or on the developer's site, usually after linking the game account to Twitch. Watch time only counts while a participating streamer is live. Twitch's developer guidance says Drops should be non-transferable items of no monetary value: common examples are cosmetic skins, beta access to an unreleased free-to-play game, and in-game currency used for cosmetics. It recommends against items that give a gameplay advantage and fully disallows anything with monetary value, such as tradeable items, cryptocurrency and NFTs. For a standard time-based Drop, Twitch suggests 15-30 minutes of watch time, while higher-value rewards such as limited-time skins usually take around 3-6 hours. Developers tend to run campaigns around big moments: world premieres, betas, new seasons and esports tournaments. Twitch says 41 million Drops were claimed across over 6,000 campaigns in 2024.
