Game publisher Amazon Game Studios has rolled out Twitch’s first currency and gambling systems on Thursday against a backdrop of a major gambling scandal that dogged the Steam gaming marketplace.

Arstechnica reported that Twitch’s currency called “Stream+” will be seen first in the upcoming sports-brawling multiplayer game Breakaway. The currency was revealed by an Amazon representative while describing how the new game will “integrate directly” with Twitch during the annual TwitchCon on Thursday.

The game publisher’s representative also gave fans a brief snippet of Breakaway action that confirmed viewers’ ability to wager on matches and “earn Stream+ Coins by watching.”

Amazon, however, offered little details on how the coins could be spent and what they would unlock, either within Breakaway or throughout the Twitch ecosystem. The firm, according to the report, also failed to mention whether Stream+ currency could be bought, sold, or traded.
