Book of Ra card on Mottle Fen
Kiwi players can open the session page for Book of Ra pokie apart from this catalogue.
Mottle Fen records Book of Ra for New Zealand: studio Greentube, high volatility, RTP 94.26%. The button hands the pokie to Here2Win Casino. Nothing on this page changes the reel maths, and POLi does not either.
What this pokie is
Mottle Fen writes the Book of Ra entry for this host. Greentube made it. Here2Win Casino is where it is played. The stake shows as NZ$.
The preview under the title is there so a snippet and the page say the same thing. If the list above has a gap, the preview keeps the gap.
The video group is where Mottle Fen files this pokie for New Zealand. Open a neighbour from the same studio if you want a second title. Each of those pages repeats the handoff: this domain, then Here2Win Casino.
Studio
If the only question was who built Book of Ra, the answer is Greentube. Here2Win Casino does not either.
