Book of Mystery Pyramids card on Yukon Reels
Players in Canada can open the session page for Book of Mystery Pyramids slot apart from this catalogue.
Players looking up Book of Mystery Pyramids from Canada land on this Yukon Reels page: studio Onlyplay, high volatility, RTP 95.55%. The spin happens at Here2Win Casino. Interac and the stake in C$ live there, not on the catalogue.
What this slot is
Yukon Reels treats Book of Mystery Pyramids as a long-looking list item that should still be a short session. Onlyplay built it. Here2Win Casino runs it for players in Canada.
If you only needed the studio, it is Onlyplay. If the fact list has no RTP, there was nothing honest to put there. The rest of the Onlyplay slots are one click away on the provider page.
Onlyplay built Book of Mystery Pyramids. Yukon Reels does not re-rate the math and does not add stars. The high-volatility label is copied from the card. A feature either triggers in the session or it does not.
100 Joker Staxx is in Video Slots too, from the studio Playson.
Studio
Onlyplay made Book of Mystery Pyramids. Yukon Reels does not re-score the math. The figure, if the card has one, is the published RTP and nothing else.
