I was told by Robert that about 5% of the 98% return is dedicated to the progressive jackpot. So, for people who don't hit the jackpot, they can expect about a 93% return on all the games (He actually said players average 92 -94%).
I should also note that Slotland will include the bonuses they give you (signup, 10% after each $1000) as part of your WINNINGS from slot play. The only reason they would do such a thing is to try to trick players into thinking that they are experiencing a greater return than they actually are. Robert denies it, but I feel they include these bonuses as part of their advertised 98% payout. (Which they say is certified, but I have yet to find someone who will claim to have certified it).
