Yes they are rigged. Everything is rigged. All poker sites
are rigged. Especially at PokerStars
where there are like 50,000 people playing at any given time. And especially the WCOOP. That's rigged too. As soon as you register, they have a complex algorithim that predetermines what spot you finish in. But what ever spot that is, it will be no better than the bubble. What a scam. And you know the sites are rigged if you take a bad beat.
In fact, I'm not sure why you play online poker at all.
