I guess we should continue to play at casinos that we have success with. I had wins/loses with most of softwares, except microgaming. I've heard many good things about their games. I myself like several games they have, and I tried many times with many different microgaming casinos. I just want to win for 1 time, lol, but I'd never have that experience, all my deposits gone quick, $100 deposit lasted me for 10 min, I bet small per spin too. I decided to give up and uninstalled all of microgaming software casinos.
I also noticed that when I bet small, the machines keep hitting, give me all kind of bonuses/free spins and this happened to most casinos (all software types). Last week I spin $1.25 per spin on PayDirt (RTG), kept on losing, I was pissed and changed it to 50 cents per spin, I got free spin on "gold fever" and that one spin gave me $450.
TAADAAA ill hit it

if its just for bonuses it must be way much out there. for me, i always look for the playthrough. i love microgaming casinos, they have a ususall 30/35 times playthrough though and are pretty tight, have to tell u a small success of mine though, i had a 10 freebie, i played 0.5 spinns till i ran out and just playing doen to single lines to get account to zero, on my second last, 0.02 i hit frespins on one single line and won 70. i know its not much, but comparing i did bet 0.01 on a single line.
i dodnt like the topgame ones, just cause they arent fun to play in, by my preferances.
some friends have had luck there though.
im a sucker for all cryptologic games, marvel and movie slots, have just had small .cashouts, and cashouts and service imo are under standard.
i havent hit any big yet (meaning no million wins, hust a few thousand or so) most of my cashouts have been from microgaming though
