Slot Summary

An interest in unusual reel geometry is a good reason to try Mermaid Riches, PG Soft's underwater fantasy slot. Its staircase-shaped playing area reverses during free spins, making the mirror motif part of the rules. The mermaid palace supplies the setting, while that reversal gives the bonus a distinct spatial identity.

How It Plays

Winning combinations run across adjacent reels from the leftmost reel. Matching symbols can occupy different positions within those reels, with the number of matching positions determining the winning ways.

After a payout, winning symbols disappear and symbols above them fall into the spaces. Another combination can then pay, and this sequence continues until no further win forms.

Theme & Atmosphere

The setting is a concealed palace beneath the sea, where mermaids guard an inherited treasure. An invisible barrier separates their home from the human world outside it.

The accompanying story gives the Mermaid Princess a personal connection to a human rescuer. Her promise of help turns the hidden palace into a destination with a narrative purpose.

Fantasy Underworld Sea

Bonus & Free Spins

Three scatters trigger eight free spins, with two more awarded for each additional scatter. The bonus uses the mirrored reel arrangement and multiplier values of x2, x4, x6 and x10.

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 (Medium). The model is calibrated so the average return equals this slot's published RTP (96.71%), with wins capped at its top multiplier (3,513×).

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.
