How to cite

Slot Summary

The reel grid in Octopus Deluxe refills from below, giving GMW's underwater slot a movement that fits its setting. Winning symbols disappear and replacements float upward like bubbles. That connection between the sea setting and the direction of play gives the game a more specific identity than its octopus mascot alone.

Bonus & Free Spins

Pearl scatter symbols trigger the pearl feature, where collecting pearls can award multipliers or direct prizes. The pearls therefore serve a separate purpose from ordinary matching symbols in the base game.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (High). The model is calibrated so the average return equals this slot's published RTP (95.10%), with wins capped at its top multiplier (1,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
