Mermaid Mighty Reels Demo: Discover an Underwater Adventure With Plenty of Features

The Mermaid Mighty Reels game was released in April 2025, by a slot provider that has fallen under the radar in recent years. Light and Wonder has been a dedicated game provider since 1973, and once upon a time, they were considered one of the best slot game providers in the entire world. Now, with a revolution in online slot games, newer providers such as NetEnt, Habanero and Pragmatic Play have produced more popular games. This Mermaid Mighty Reels slot is Light and Wonders’ attempt at a comeback, and we have to say, they have made a solid case for themselves. 

It’s a gameplay experience that feels fresh, and unique for a variety of different reasons. For one, the graphics certainly live up to Light and Wonders reputations. There are also some high multipliers to be won. But, the major factor that makes it feel different is the features available to the player. We will discuss them in detail throughout this review and you can also try the Mermaid Mighty Reels demo that we have embedded at the top of the page.

Mighty Mermaid Reels Features

These are the main ways to win in the Mighty Mermaid Reels slot:

Mermaid Wilds

The Mermaid Wilds are a slight adjustment to your classic wild symbols you would find in most slot games. Mermaid Wilds are available on all symbols except for Scatters and Pearl symbols. Not only do they replace symbols like classic Wilds, but they also fully expand to unlock the top three reels. If you have already unlocked the top three reels, then they will act as expanding symbols, and substitute symbols across all of the reels. 

Pearl Symbol

The Pearl symbol will appear on reel 2, 3 and 5, and they will act as a straight cash prize. The cash prize for the Pearl symbols can range from 0.5x to 10x your bet. If you get a Mermaid Wild at the same time that you get a Pearl symbol, the Mermaid Wild symbol will expand to collect all the Pearl symbols on that reel. 

Premium Play

You can activate the Premium Play feature for a cost of increasing your current bet by 50%. Once this is done, any wins greater than 2.5x your bets will activate the Premium Play bonus. What this will do is offer you a range of multipliers between 1x and 5x your wager, and four individual free spins segments. 

Mighty Mermaid Reels Free Spins and Bonuses

The Mighty Mermaid Reels free spins are activated when you land 3 scatters on reels 3, 4 and 5. This will activate 8 free spins for you to enjoy, and the key to succeeding at these free spins is focusing on getting as many Mermaid Wilds as you can. 

The Mermaid Wilds in the free spins rounds automatically unlock the top three rows, and will collect all pearl winnings across the entire board. If you land 3 more scatters in the free spin rounds, you will win 8 more free spins. It also does not matter if you hit a full, or partial Mermaid WIld, it will expand all the same in the free spins round. When reviewing this game with the Mighty Mermaid Reels demo, we found that this is the most profitable way to build up your bankroll.

Mighty Mermaid Reels Theme and Symbols

Light and Wonder have always been known for their smooth and top level graphics that focused on memorable and well-crafted video slot graphics. They stick to that aesthetic for this outing, but you can definitely tell they have upgraded the quality of their graphics. The winning animations feel far smoother, and the overall vibe of the game stays true to what they are trying to achieve. The titular mermaid is at the forefront of the screen, and the brightly coloured background feels like you are deeply immersed in the sea. 

Some of the symbols include a trident, treasure, jewellery, the Pearl represents cash prizes and the mermaids represent the expanding wild symbols that offer the highest multipliers in the game. It’s a theme and aesthetic that has been done before in slots, but Light and Wonder have made impressively it their own with Mighty Mermaid Reels.

Mighty Mermaid Reels RTP and Volatility

Mighty Mermaid Reels has some big wins available to the player, with the max payout being a whopping 2,064x. However, the amounts you can bet are much lower, and you will find the wins come a lot more frequently than you’d expect. So, Mighty Mermaid Reels is a low volatility game. A low volatility game offers frequent wins at a lower amount, but a high volatility game offers less frequent wins, but when you do win, the wins are bigger. 

The RTP is around average. It is 96% on the button, which is the industry standard for many of the high level slot games on the market. However, considering how low the volatility is, this balances out well for a good amount of returns for the player. Still, if you prefer the chance to win bigger prizes then we can offer Muertos Multiplier Megaways as an alternative; this memorable slot from Pragmatic Play has a 10,000x max. win and high volatility.

How to Play Mighty Mermaid Reels 

Light and Wonder games have a distinct playstyle, that focuses more on minimizing the amount of buttons and instructions on the screen, to maximise the player enjoyment. If you are used to playing any other slot game, it will take a while for you to adjust to this layout. But, once you play it for a while, you may find that you enjoy the minimalist layout. 

Rather than any buttons being across the button, like most other slot games, the main buttons you have to worry about in Mighty Mermaid Reels are either side of the reels. On the right hand side, you’ll have all the major playable buttons. The play button is the large green button, and the autoplay button is the rotating button above it. You can also check your balance with the button at the top of this side of the screen. 

On the left hand side, you will have the Premium Play button, which toggles this game mode on or off. You can also toggle the Gamble mode on or off, which allows you to gamble every win you make for extra wins, or some free spins. That’s all the buttons that you need to know. If you try out the Mighty Mermaid Reels demo free play, we are sure you’ll get the hang of this gameplay within a few minutes. It’s brilliantly simple. 

Slotsia’s Review of Mighty Mermaid Reels

Mighty Mermaid Reels seems like it’s Light and Wonders’ major comeback, to make a serious splash in the themed slots world. We certainly believe it has made an impression. An interesting theme, that is supported by a multitude of different Mighty Mermaid bonus features, and rewards for a player to potentially win. It’s also a low volatility slot, so the chances of many players winning are increased. 

However, the RTP isn’t excellent, and there aren’t many big time rewards for high rollers to win. Still, we feel this is one of Light and Wonder’s best games, and we would recommend investing some time in it yourself.
