Gameplay Overview

This slot runs on a 5×3 grid using 120 paylines and the Paylines payout system. With an RTP of 96.71% and high volatility, Mermaid Riches delivers high-energy sessions where wins can arrive in bursts. Expect a maximum win of 3513× your stake, and flexible bets ranging from 0.20–20. Keep your bankroll steady by pacing spin sizes and session length.

What makes this slot unique is its progressive reel layout: Reel 1 starts with just 1 row, Reel 2 expands to 2 rows, Reel 3 to 3 rows, Reel 4 to 4 rows, and Reel 5 reaches 5 rows — creating the distinctive 1-2-3-4-5 configuration. This staggered structure generates the 120 paylines and keeps every spin visually dynamic and unpredictable.

Bonus Features & Mechanics

Mermaid Riches packs several interlocking features that reward both patience and timing:

Special Sticky Wild: At the start of each spin, a Special Sticky Wild can land on the reels with a counter displaying 1, 2, or 3. This Wild sticks in place and moves to a random position after each spin. Each time it contributes to a win, its counter decreases by 1. Once the counter reaches zero, the Wild vanishes. Strategic spins with active Sticky Wilds amplify your hit rate.

Progressive Multipliers: Displayed above the reels, multipliers start at x1 and increase progressively up to x5 in the base game as rounds advance. Any win is multiplied by the current overhead value, turning modest combinations into stronger payouts.

Free Spins Round: Land 3 or more Scatter symbols anywhere to unlock 8 Free Spins. Each extra Scatter adds 2 more spins. During Free Spins, multipliers climb higher — x2, x4, x6, and up to x10 — and the reel structure flips into a mirrored 5-4-3-2-1 layout, shifting symbol distribution and creating fresh win patterns. Retriggers are not possible, so maximize every free round.

Symbol Paytable

Mermaid Riches features aquatic-themed symbols arranged across high-paying, medium-paying, and low-paying tiers. The highest-value icons include ornate Pearls, Treasure Chests, and Golden Vases, delivering multipliers up to 150x for full combinations. Medium-value symbols feature marine creatures like Eels, Rays, Jellyfish, and Starfish, awarding between 20x and 75x for matching sets. Lower-value symbols are represented by classic card ranks (A, K, Q, J), which provide 5x to 20x payouts.

All wins are boosted by the progressive overhead multipliers and elevated further during Free Spins when multipliers reach up to x10. Understanding the symbol hierarchy helps you recognize high-value combinations and anticipate potential win sizes in both base and bonus gameplay.

Its high-volatility profile rewards patience, and the sea life presentation feels cohesive and modern. If you like calculated risk with clean math and generous bonus swings, this one deserves a spin.
