yes I've played on 888 for about 3 years but very rarely, I was a little tiddly one night and the Mrs was moaning at me and I didn't pay attention on my first bet on the roulette wheel forgetting the chip counter starts on $25, $25 on Red 25 then......
it came in $900
that night I won $3,500 from a £200 start point, they paid out so much back onto my Switch Card but then the rest was sent by cheque which took about 10 weeks to finally be deposited into my account
having said that I have played many times and lost the lot, usually no more than £50 so I would hazard a guess I am not up by much if at all. Think of it like a fruit machine they are going to payout 90% of what goes in sometimes you'll be lucky and sometimes you won't, so only bet what you can afford to lose.
