Found this RC. It gives BJ A=0.005 (0.5%) so Slots would be A=0.05 (5%) me thinks.
An example of calculating EV
As an example - a site has a bonus promotion offering a £30 bonus with a 100xWR and Blackjack can be used to complete the WR. This gives us:
Wagering Requirement, W=£3000 (30x100)
House Advantage, A=0.005 (very roughly assuming 0.5% for Blackjack, ie for every £100 you spend on BJ, on average the house takes 50p)
Expected Value EV = B - W*A = £30 - £3000*0.005 = £15
So over £3000 of wagering on Blackjack, all things being equal you can expect to lose £3000*0.005 = £15. This is the 'house take' or 'house advantage' - if you were not playing with a bonus you would simply lose £15 over £3000 of wagering. However because you are starting with a £30 bonus, after £3000 of wagering you will be left with £30 - £15 = £15. So the expected value of the bonus is £15.

i am trying to say that achieving a cash out may well be easier without a bonus if a person is looking at x times deposite and qualifying for min payout
example i deposite 50.00 and run it up to 450.00 in a half hour maby only 3x rollover im cashing out
what example will be a comparable, with a bonus , how much roll over must you do to cash out 450.00
from a 20 x dep and bonus of 50.00 +50.00 and thats on the short end of most rtg casino =2000.00 before the ability to cash out
if im missing something please chime in
Sorry buddy, you missed the boat.
It,s a bit like those deals when you book a cruise. Pay $2000 and you get $100 on board credit. Your price pays for the deal.
Deposit $50 and if you get real lucky after $6000 wagering, you can withdraw some money but most likely you will lose the lot.
You are so much better these days to deposit without a bonus at a reputable casino ie (32red) and hope for the best and if u hit a jackpot withdraw without any WR.
Todays bonuses are designed for gaming addicts.
Well heck I keep thinking if I was supposed to win $200 x 30 that would equal to $6000, therefore I would have to win $6000? Well that was my theory. I did mention, I had no 'idea' how bonuses worked :P
I took the safe road and turned down the bonus. The odds just seemed to high
Im forever getting offered bonuses but since I havent really cottoned on to how they work, I've always stuck with just straight deposits.
However was the first time I'd actually won at one of those free play hour thingies so the temptation was great, but irrelevant now since I turned it down
