Do you seriously think the slots pay differently on a free chip? i.e. better? Why would the casino want that? How would they even DO that? Have a different version of the game for every individual player depending on whether they were using a free chip or a coupon or their own money?
You are NO more likely to hit a jackpot on a free chip. The odds are the same. Nobody has ever provided a shred of evidence to the contrary, nor any to support such tin foil hat theories as different RTPs for different players and different coupons and different games at different time etc etc. It might SEEM that you are more likely to hit a RJ on a free chip if you have only hit them on free chips, or the majority of them at least...all it means is that you play a lot of free chips (and therefore perhaps bet larger increasing your chances) or that you were just luckier at the times you were playing free chips. However, "seems to me" means nothing in reality as slot RTP is not based on individual players and for every RJ that someone complains about winning on a free chip, there are likely 5 times as many with deposited money that we don't hear about because only a tiny portion of the gambling community visits and posts at Casinomeister.
I've said it once, and I'll say it again. If anyone REALLY thinks this "live tampering" with slot play according to what kind of money you're using or what coupon you're using etc etc is REAL, and continues to PLAY, well it says a lot about how much they REALLY believe their own theories. Alternately, it says something about how......well I'm not going to say it.
Many casinos now are deducting excess winnings after meeting WR. Personally I think it sucks and it annoying especially when you are on autoplay, but they do it to stop players running up huge comp point balances IMO, so I guess I can see the reasoning.
In regards to bonuses at RTG, what I really don't like is that the wagering requirement is not shown until after you deposit. I can't see how it would be hard to show it in terms of "x D + B" when redeeming the coupon before the deposit is made. I've seen offers in the marquee area of the lobby several times and gone to claim it and been unable to find any WR details...so I just cancel the coupon.
