I put the free blackjack game link on my site (€ currency) and some strange things happened. First I had it set up for one particular game (blackjack) at Challenge Casino and it landed in the free play lobby of Golden Reef. Then interstitials of Music Hall casino came on.
On another test drive there was an interstitial for Aztec Riches Poker!!! It was tagged to me but I really doubt that that would do any good as you don´t promote that program.
