I don't like this type of game.
For me it is pure gambling.
I can't remmember what is biggest prize,but i will say $10.
Again i don't like this type of poker.
That format is rare. I have only won 2X the BuyIn. I have not had the luck to win more than that. I don't really like that game format, it's also because I never win more than Double BuyIn, I don't play this spin game format more often.
I've played a few times for $ 1 and $ 2, but I personally don't like this tournament, because at least from what I've seen, you can't win a lot of money only if you play in bigger tournaments.
