What this pokie is

Session math & RTP benchmark
Book of Skulls Uncharted Treasure does not carry an individual published RTP on its source sheet, so no single-title percentage is guessed. Across the 106 Spinomenal titles that do publish a return in this catalogue, the studio average is 95.96% (ranging from 95.42% to 96.44%). 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$95.96 | A$4.04 | ~27–33 |
| 250 spins (A$1/spin) | A$250 | A$239.90 | A$10.10 | ~68–83 |
| 500 spins (A$1/spin) | A$500 | A$479.80 | A$20.20 | ~135–165 |
