Something that I don't like about Club Gold is that buried in their T&Cs is a term that if you take their SUB and meet the wagering, you're only allowed to cash out 10x your deposit or $5000 (whichever is lower)
Also, I was told that their slots only count 50% towards wagering.
I opened an account but have yet to deposit, I'm not sure that I ever will because those two things seem weird to me. The first one especially since you are allowed to play progressive games with the SUB. But if you happen to win, you're tied to a max cashout and they get to keep the rest of the progressive pool.
On the flip side, their support is good and friendly and all that - and maybe if you play without bonuses they'd be ok....but there are other playtechs that are better IMO.
