Editorial analysis
Verdict up front: the return is corroborated but below par. Two feeds — slot.report and slotslaunch — both read 95.72%, and that agreement is the useful part, because a confirmed figure beats a generous one nobody else has seen. The reading trails the 96.08% midpoint of our 9,233-game sample by 0.36 points.
Six reels, fixed lines and a double-sourced 95.72%
The grid runs six reels wide on a fixed payline count rather than an expanding ways engine. Nothing cascades. Volatility is logged at 5 of 5, so the distribution leans toward infrequent larger results, and stakes are accepted from 0.10 up to 40 per spin — one game serving very different bankrolls. OctoPlay put it out on 20 April 2025 and we track 212 of the studio's games. No max-win figure has reached our feeds, so we cannot quote a ceiling for it.
Mining fans of the patient sort. Anyone wanting a published cap should wait for better data.
Price of admission at 95.72%: near 4.28% of turnover ends up with the house once enough spins accumulate. Name your ceiling first. Strictly 18+.
