I don't play these games but how does this work compared to betting during tournaments?
I think it runs with the same mechanics as the tournament rules, if the streamer won a game then you will also win the bet.
Would these Twitch gamers announce ahead of time when they'll stream their game so people can bet?
Basically, if you follow a twitch streamer you will likely know the gamers playtime
I have only found 3 streamers in the site and they all suck at playing the game. Just look at their win rate ratio.
