Users and creators will have until 17 August to remove links and referral codes from their channels, after which they could face sanctions.
Twitch added that it will continue to monitor the sharing of other gambling-related content across its platforms and would update its rules again if necessary.
“To prevent harms and scams created by questionable services that sponsor content on Twitch, we will prohibit sharing links and/or referral codes to sites that offer slots, roulette or dice games,” Twitch said in a creator update.
Twitch specialises in live streaming video games including broadcasts of professional esports competitions and events.
Users and content creators are permitted to post links to websites offering certain services and products, with many being paid to share these links.
