What this pokie is
Pokies Baron keeps the entry short. Diamond Mystery - 40 Charming 7's is a Greentube pokie for Australia, opened at Here2Win Casino. The figures are the card, not a house view.
The fact list repeats the studio, the volatility and the RTP so a search snippet and the page agree. One lucky spin is not the RTP arriving early.
Melbourne does not change the reel strip of Diamond Mystery - 40 Charming 7's. What changes is the stake you set at Here2Win Casino. Pokies Baron only keeps the written facts beside the name.
