Mermaid Royale is designed with themes like Mermaids, Underwater, Water, in mind. The layout of this game is pretty standard and consists of 5 reels with 25 possible paylines. In most jurisdictions you can also select the Autoplay option when playing Mermaid Royale. You can choose from 10, 25, 50, 100 or even more spins. You can opt to stop Autoplay on a win, if a single win exceeds a certain amount, or if your balance increases or decreases by a chosen amount. This is a great way to stay in control and to play more responsibly.

Maximum Win, RTP and Volatility

The maximum win in this game is capped at 2000x your total bet, which places it slightly below the average max‑win potential found in many modern online slots. Even so, it still offers the chance for solid payouts, especially during the game’s stronger features. With a bit of luck, players can secure a meaningful boost to their bankroll, making the slot appealing to those who prefer moderate win potential without extreme volatility. This value is calculated on a very large number of spins, often a billion spins.

The standard RTP for Mermaid Royale is 95% (Can be lower on some sites). This is quite low and considered to be below average for an online slot. RTP stands for Return to Player and is the percentage of stakes the game returns to the players. For example, if a player bets €10 the expected return for this game would then be €9.5. However, the RTP value is calculated over millions of spins which means the outcome of every spin will be totally random.

Mermaid Royale is a high-volatility slot, with Realtime Gaming rating its volatility at (3/5). In slot terminology, volatility describes how frequently a game pays out and the size of those payouts. This means Mermaid Royale delivers fewer wins overall, but the payouts it can produce are significantly larger compared to low-volatility titles. It’s built for players who enjoy high-risk gameplay, sharp adrenaline spikes, and the potential for substantial rewards in exchange for longer dry spells.
