How to cite

Slot Summary

Choose the stake first, then accept Story of Amaterasu's 95.78% RTP and High volatility as the terms of a Wild-led game. Spinomenal places the Japanese sun goddess at the center of both theme and mechanics: expanding Wilds can cause a re-spin, random Wilds can alter ordinary rounds, and Scatters open free spins. The x3000.00 ceiling gives those interventions a clear limit.

How It Plays

The base game uses 5 reels and 20 paylines, but its defining movement comes when an expanding Wild holds position and prompts a re-spin.

Random Wilds can enter ordinary spins without requiring the free-spins trigger, giving the base loop a separate source of symbol substitution.

Theme & Atmosphere

The Mythology theme focuses on Amaterasu, the Japanese sun goddess, making divine intervention a literal part of the game's visual and mechanical identity.

Rather than treating Mythology as detached decoration, the design connects its central figure to expanding and random Wild events that interrupt the regular reels.

Mythology

Features & Win Potential

The expanding Wild is the stronger feature because it remains in place for a re-spin, preserving one useful position while surrounding symbols change.

Random Wilds provide a less predictable intervention, adding Wild Symbols to ordinary play without requiring the Scatter Symbol or Free Spins round first.

Bonus & Free Spins

Scatter Symbols trigger Free Spins, moving the Wild mechanics into a dedicated round where their effect can be observed across several spins.

Additional Free Spins can be awarded by further Scatters during the round, allowing the feature to continue beyond its original allocation.

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 (95.78%), with wins capped at its top multiplier (3,000×).

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.
