The first program we are auditing is jackedaffiliates.com which currently has 2 casinos: Casino Mate House of Jack We have a 45% revenue share deal with them. We deposited 20 AUD at House of Jack which was converted to 13.35 euros in the affiliate program. They took an additional fee of 50 cents AUD: We took the 100% bonus We played slots: And we lost all of the funds deposited and bonus. Our earnings were 2.86 euros from the 13.35 deposited which is an effective revenue share of the money lost of 21.4%. So to summarise the Effective Net Gaming Revenue (the amount of money deposit and lost) is 6.35/13.35 = 47.6%. Multiply the advertised or your revenue share rate by the Effective Net Gaming Revenue (47.6) to get the/your real rate.
