The Great Jackpot Expedition by OctoPlay: headline RTP 95.80%, Low volatility, max win x2 500.
An RTP of 95.80% means a house edge of 4.20% — the expected cost is 4.20 units per 100 staked over the long run, whatever a single session does.
The Great Jackpot Expedition is a low volatility game: wins land often and small, which makes the bankroll curve smooth without changing the long-run cost.
The advertised ceiling is x2 500. Max win figures describe the tail of the distribution, not a realistic target: on most games with a ceiling this high the probability per spin is below one in a million.
Against our catalogue the number is below the median of 96.13%, higher than 25% of the games whose RTP we verified. That comparison matters more than the raw figure, because "96%" only sounds generous next to nothing.
Released 2024-10-28. Release date matters for RTP: newer titles are more likely to ship with several configurable builds, which is what lets two casinos price the same game differently.
Stakes run from 0.1 to 400 per spin on a 5 layout with fixed betways.
The Great Jackpot Expedition is one of 138 OctoPlay titles in our catalogue, a studio averaging 95.06% RTP across the games we could verify.

Yes. The Great Jackpot Expedition has a free demo with the same mathematics as the real-money version — the only thing that changes is that the balance is not yours. A demo cannot tell you the RTP build a particular casino serves.
The Great Jackpot Expedition is a OctoPlay game, so the outcome is produced by the studio's certified RNG rather than by the casino, and it is not provably fair in the cryptographic sense — you cannot recompute a spin from a seed. What the casino does control is which RTP build it serves. That is the real variable, and it is measurable.
