What this pokie is
Boomerang Pokies sends you out and back: read Diamond Mystery 40 Imperial Crown here, play it at Here2Win Casino, return to the same URL if you want the figures again. The name is the catalogue, not a mechanic.
Greentube is the studio on the Diamond Mystery 40 Imperial Crown card. That is the fact worth trusting on this page. If the session feels fast, that matches a pokie. Set a loss limit before the first spin.
The preview under the title is the short form of this card. A search snippet should match the page. Boomerang Pokies does not decorate the preview with a guessed return.
From the same studio list, Fortune Fishing is the nearer name and Simply Wild SuperGame is the one after it.
The studio behind it
Greentube is the studio printed on Diamond Mystery 40 Imperial Crown. Boomerang Pokies lists 419 of their pokies for Australia, and this is one of them. Open that page if you want a neighbour title from the same studio.

Session math & RTP benchmark
Because the source card for Diamond Mystery 40 Imperial Crown omits a standalone RTP, Boomerang Pokies uses the verified studio distribution as context rather than inventing a figure. Across the 135 Greentube titles that do publish a return in this catalogue, the studio average is 95.05% (ranging from 92.13% to 96.45%). For a balanced session at Here2Win Casino, a bankroll buffer of 200x–250x the A$ unit stake suits this pokie's profile.
| Session volume | Total turnover | Theoretical return | House margin | Est. winning spins |
|---|---|---|---|---|
| 100 spins (A$1/spin) | A$100 | A$95.05 | A$4.95 | ~27–33 |
| 250 spins (A$1/spin) | A$250 | A$237.63 | A$12.38 | ~68–83 |
| 500 spins (A$1/spin) | A$500 | A$475.25 | A$24.75 | ~135–165 |

This card does not carry a volatility mark, so Boomerang Pokies does not guess who Diamond Mystery 40 Imperial Crown suits. The studio is Greentube. The session still opens at Here2Win Casino.

Coming back to Diamond Mystery 40 Imperial Crown later does not make it due. Keep the A$ stake where you left the rule.
The maths does not soften because the catalogue page is long. Walk away while the stake in A$ is still a choice.

- Stop on a clock you set in Brisbane, not when the pokie 'looks due'.
