Mermaid Princess

Mermaid Princess by KA Gaming tells an underwater royal narrative across 10 paylines, with expanding Wilds covering entire reels and triggering Respins as the game's core mechanic. Landing an expanding Wild effectively converts that reel into a full-column wild for the respin that follows, compressing the bonus into tight, reel-coverage-based sequences rather than extended spin counts. The 96.0% RTP and medium volatility make this a measured slot, with 18.99% hit frequency rounding out the picture. Play is available on desktop and mobile with crypto at Wild.io.

What is Mermaid Princess?

Mermaid Princess is a 5x3 video slot from KA Gaming with a 96.0% RTP, medium volatility, 10 paylines, and a hit frequency of 18.99%. Its standout mechanic is expanding Wilds that cover full reels and trigger Respins, alongside a free spins round offering up to 25 spins.

The 10-payline structure gives the game a narrower base than KA Gaming's 20 or 25-payline titles, concentrating wins onto fewer crossing lines. The expanding Wild mechanic compensates for this by converting entire reels into wild columns during Respins, which can activate multiple paylines simultaneously when the wild reel aligns with matching symbols on the adjacent reels.

Who will enjoy this game the most?

You will probably enjoy this game if you like:

• Ocean and mermaid theme fans who want a royal underwater narrative rather than an adventure framing
• Players who enjoy expanding Wild mechanics where a single Wild converts a full reel column
• Medium-volatility fans who want Respins as the primary bonus trigger rather than scatter-only free spins
• Crypto casino players looking for a lower-payline slot with a distinct bonus mechanic
• Players comfortable with a 18.99% hit frequency typical of medium-volatility 10-payline slots

How To Play Mermaid Princess Slot - Step By Step

Head to Wild.io and create a free account to start playing Mermaid Princess.

1. Load Mermaid Princess at Wild.io and set your stake on the 10-payline layout.
2. Spin to match mermaid and ocean symbols from left to right across any of the 10 active paylines.
3. Watch for the Expanding Wild symbol to land on any reel. When it does, it expands to fill the entire reel height and a Respin triggers automatically.

5. Land three or more Scatter symbols to trigger the free spins round, which awards up to 25 spins with full Wild behavior active.
6. Use Wild.io's responsible gambling tools to manage your session across the free spins run.

Mermaid Princess Slot Theme & Graphics

The setting is a deep ocean kingdom, the kind of underwater court where royalty and sea creatures coexist. KA Gaming's art direction uses soft aquamarine and pearl-tone backgrounds, with the mermaid princess rendered in full regal detail: a crown, ornamental scales, and flowing underwater hair. The supporting cast of sea creatures and coral palace architecture fits the royal framing without feeling crowded.

Animations trigger when the expanding Wild fires: the reel glows and expands with a wave-like motion before locking into position for the Respin. Sound design uses gentle harp progressions in the base game that shift to more dynamic orchestral elements during the expanding Wild sequence. Mobile play holds the 5x3 grid and 10-payline layout without layout changes.

Mermaid Princess Slot Symbols & Paytables

The symbol set in Mermaid Princess runs from ocean-themed low symbols through mermaid royalty premiums, with the Expanding Wild and Scatter driving the game's bonus mechanics.

Low Value Symbols

Low-value symbols include pearls, decorative shells, and small sea creatures styled to match the royal underwater setting. These appear across all five reels and pay on three or more from the leftmost reel across the 10 paylines. The 10-payline structure means fewer simultaneous win paths than wider layouts, so low symbols tend to contribute individually rather than in multi-line clusters during base play.

High Value Symbols

Premium symbols include the Mermaid Princess herself as the top-paying icon, flanked by treasure chests, royal crests, seahorses, and ornamental ocean artifacts. The princess symbol pays the highest for five positions across a payline. Mid-premiums in the three-to-four position range represent the base game's core win engine between bonus triggers.

Special Symbols

The Expanding Wild is the game's defining symbol: when it lands on any reel, it expands to fill all three rows of that reel and triggers a Respin with the expanded column locked. This converts the wild reel into a full-column substitute that activates all 10 paylines crossing it. The Scatter triggers the free spins round when three or more land anywhere on the reels, awarding up to 25 spins. During free spins, standard Wild symbols maintain substitution behavior while the full 10-payline structure remains active.

Mermaid Princess Bonus Feature & Special Features

Expanding Wild with Respin

The Expanding Wild is the most frequent bonus event in Mermaid Princess. When the Wild symbol lands on any reel, it expands vertically to cover all three rows of that reel and locks in place. A Respin then fires automatically with the locked wild column held. On the Respin, the remaining four reels spin freely, and any wins formed with the locked wild column are collected. If another Expanding Wild lands on a different reel during the Respin, it also expands and locks, and another Respin triggers. This chain can extend as long as new Expanding Wilds continue to appear, though the probability decreases as more reels become locked. Two or three locked wild columns in a Respin chain across a 10-payline grid can activate multiple lines simultaneously, generating the slot's mid-range win outcomes without requiring the full free spins trigger.

Free Spins (up to 25)

The free spins feature triggers when three or more Scatter symbols land anywhere on the five reels. Mermaid Princess awards up to 25 free spins, which is a high free-spins count compared to many KA Gaming titles. During the bonus round, the standard 10-payline structure remains active and Wild symbols substitute normally across all lines. The Expanding Wild behavior may also apply during free spins, meaning a wild landing during the bonus can expand, lock, and chain Respins within the free-spins round itself. This interaction between the two mechanics is where the free-spins round can deliver its largest outcomes.

Jackpot Feature

Mermaid Princess includes a jackpot prize layer alongside its 10-payline base structure. The jackpot is a fixed-prize component that activates through normal gameplay rather than a separate pathway. For a 10-payline slot with medium volatility, the jackpot provides a prize ceiling above what standard payline wins can reach, giving the game an additional target beyond the Expanding Wild and free-spins mechanics.
