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.
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.

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.
The RTP of Mermaid Riches is 96.71%, paired with high volatility. In practice, outcomes can vary sharply — sessions may feature quiet stretches followed by strong bonus bursts. Over time, players can expect theoretical returns close to the stated percentage, but short sessions will deviate.
Mermaid Riches operates with 120 paylines using the Paylines mechanic. In plain terms, wins form when matching symbols land on adjacent reels (usually left to right), which keeps action lively and supports frequent smaller hits even with a high-volatility profile.
The maximum win potential reaches 3513× your stake. Such outcomes are rare and typically occur during Free Spins or multiplier-boosted sequences. Aim for consistent medium wins, set session limits, and avoid chasing top-end results.
Free Spins usually trigger when three or more Scatter symbols land in a single spin. Retriggers may add extra spins, while bonus modifiers like sticky wilds or increasing multipliers can amplify momentum. Use this phase to capitalize on stacked value.
Bet sizes range between 0.20–20. Local currency equivalents may vary by operator, which makes the game suitable for quick sessions and longer bankroll-friendly runs.
Yes — where permitted by local law. Always choose licensed casinos, complete any required KYC, and review the active RTP model, bet limits, and bonus terms before depositing. Set deposit and time limits to manage risk. If real-money play isn’t available in your region, consider legally compliant social or sweepstakes options referenced above.
