I received a love letter in my mail box from Slotastic casino and there was $40 love free chip in this letter. It came one day after valentines day though, but I was still able to redeem it without a problem.
First, I played Mayan Queen in which my balance went up to $70, then I switched to play Triple Twisters. I got 5 chicken scatters (see screen shot) for initial win of $33, but its nine free spins did not win much. I kept on playing Triple Twisters and got into another bonus round in about five minutes later. The last free spin of its 9 free spins gave me a triple twisters (on 2nd screen shot), which won me around $130.
Then, my balance started to go down hill after that. Even though, I tried to play some other low variance games, but I've never had any bonus round and eventually I lost it all. I've noticed that it happened to me with most RTG casinos I played with. I think the software or the casinos like to get you into a false winning state, in hope that you most likely to make another deposit or something. Or maybe it's just me who couldn't make a cash out and just do the "whining", lol.
