PokerStars has lots of cheap tournaments with quite a big pot, 888 has LOTS of Freerolls WITH CASH prizes, but GG Poker has the BEST effects and some extra interesting best with "Flop Bet" or something like that, you`re betting on the flop, if it's with a flush, a straight, pairs, and stuff, and if you guess it right, u have an x4 or something like that as a multiplier, and it's quite ok to guess your luck from time to time. Hope it helps, I've been in for a long time on both 888 and Pokerstars but am relatively fresh on GG Poker.
