This is a frequent question - we can answer that we have no hidden admin fees.
All that there are, you can see in the formula
Affiliate Income = ((100% - royalty casino)-NG + (100% - royalty betting)*Betting - CP - (deposits+payouts)-5%) x aff %

We pay royalties to software developers, sharing this commission with the affiliate.
The royalty is 15% for casino and 20% for betting.

We also pay commissions to payment systems, sharing this with the affiliate, which is 5%
