Slot Summary

A five-reel grid that sends most of its variation into a picked bonus package defines Manta Mayhem. Play'n GO sets the catalog version at 94.2% RTP and High volatility, with a 9000x ceiling. Pearls collected by the manta can open Clam the Prize, where the selected mix of Free Spins and boosters determines how Sticky Wilds, Random Wilds, or Wild Multipliers shape the round.

How It Plays

Regular play uses 20 fixed paylines, with matching symbols connecting from the left. Pearl symbols are collected by the manta and may randomly activate Clam the Prize.

The collection display is mainly visual until the bonus activates. At that point, a clam selection establishes the number of Free Spins and the boosters governing the entire round.

Theme & Atmosphere

The Fish and Sea themes place a manta ray above an underwater reel set, with pearls serving as the link between the setting and the feature trigger.

Rather than treating the sea as decoration alone, Manta Mayhem gives the central creature a visible collecting role. That makes the bonus transition readable before the clam-picking stage begins.

Fish Sea

Features & Win Potential

Clam the Prize is a pick-objects Bonus Game that assigns Free Spins and several lasting modifiers. The possible combinations change how substitution and symbol values operate during the round.

Sticky Wilds can remain on designated middle reels, while Random Wilds add substitution elsewhere. Wild Multipliers and stacked high-paying symbols can strengthen the same line results in different ways.

Bonus & Free Spins

The selected clam awards 6, 8, or 10 Free Spins alongside 3, 4, or 5 boosters. Those boosters stay active until the feature ends.

Booster choices can add Free Spins, place Sticky Wilds, introduce Random Wilds, stack high-paying symbols, or apply Wild Multipliers. Free Spins cannot retrigger once the round has started.

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 (94.20%), with wins capped at its top multiplier (9,000×).

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.
