The Great Jackpot Expedition RTP (95.80%), house edge & 500-spin session math
The Great Jackpot Expedition by OctoPlay returns a published 95.80% RTP (4.20% house edge) across a 5×3 / 5×4 HTML5 video grid layout and calls for a 100x–150x bankroll buffer in C$ at Here2Win Casino (here2win.com.au).
This OctoPlay release stands at +0.30 percentage points against the 95.50% studio average across 34 RTP-published titles (rank #5 of 34). The low-to-medium volatility slot distributes payouts according to its certified reel weightings. Its 95.80% math model requires a 100x–150x unit-stake buffer to absorb standard variance swings. Players launch The Great Jackpot Expedition in C$ at Here2Win Casino (here2win.com.au) with full HTML5 desktop and mobile parity.

What a session does
There is no second system hiding under the name Grizzly. The slot is not due.
Skip the idea that a slot is due. One evening in Calgary is not the sample behind a published RTP.
Who it suits
A low-to-medium volatility slot tends to spend a C$ stake in smaller steps. The pace is slower. The result of one night in Calgary is still not the RTP.
