Session math & RTP benchmark
Because the source card for Book of Holla: Bonus Spin omits a standalone RTP, Boomerang Pokies uses the verified studio distribution as context rather than inventing a figure. Across the 26 Holle Games titles that do publish a return in this catalogue, the studio average is 95.43% (ranging from 92.40% to 96.23%). 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$95.43 | A$4.57 | ~27–33 |
| 250 spins (A$1/spin) | A$250 | A$238.57 | A$11.42 | ~68–83 |
| 500 spins (A$1/spin) | A$500 | A$477.15 | A$22.85 | ~135–165 |

Stake and the cashier

How you open it
