Mermaid Reef slot review

Mermaid Reef is a medium to high volatility Reel Play title featuring 5 reels, 3 rows and 10 fixed ways to win. The biggest attraction is the Pearl Bonus Game, where you pick different multiplier pearls for total wins up to 1,295x your stake. You will also benefit from a bonus round where all wins are doubled, and this is the first game to offer both a Bonus Buy feature and a Gamble Win feature in the same game.

Mermaid Reef Features

You’ll find both a bonus game and a bonus round in Mermaid Reef, so there is plenty to cover here. The animated mermaid wild will land as a 1x3 sized symbol, but it does not always land fully in view. It can land only on reels 2 to 4 (i.e. the 3 middle reels), and it steps in for all regular symbols like wilds usually do.

You can choose to gamble your winnings after each spin, and this is a standard double or nothing feature. You will guess the card suit to win 4x your stake, or the card color to win 2x, and you can gamble like this 5 times in a row.

When you land 3 clam bonus symbols on the same spin, you trigger the Pearl Bonus Game. This is a classic pick’em game, and you will make your choice from 15 closed clams. The clams you pick open to reveal a win multiplier of either 1x to 10x (white pearls), 2x to 25x (black pearls) or 50x to 1,000x (gold pearls).

There will be 1 to 3 black pearls per session, and only 1 gold pearl. The rest are white pearls, and the multipliers are combined when the feature ends. This happens when you pick a black pear, or if you’ve already picked all the white pearls and the gold pearl. If the latter is the case, you will also be rewarded the remaining black pearl (or pearls) to your multiplier boost.

Depending on your jurisdiction, you can opt to buy the Pearl Bonus Game for 55x your stake. However, this option is not available for UK players.

The free spins bonus round comes about when you land 3, 4 or 5 pearl scatters on the same spin. This gives you 10, 15 or 20 spins respectively, and you will now benefit from a 2x multiplier on all wins. You can retrigger the bonus round by landing pearl scatters as described above, and you can expect to trigger the feature every 205 spins on average.

The 200 Spins Mermaid Reef Experience

We enjoyed the relaxed vibe we got from this game, and our 200 spins test session came to a head when we triggered the Pearl Bonus Game towards the end. This is really the most exciting feature here, as the free spins round offers nothing too special. We had a decent enough time with this game, and you can check out the highlights in the video below.

Review Summary

Mermaid Reef might be the first game to combine bonus buy with the standard gamble feature, but there really isn’t anything new to see here. The biggest drawback is the low payouts combined with medium to high volatility. The base game max win is only 342.5x your stake, and the possibility of doubling this meager potential in the bonus round just feels weak.

Clearly, it’s the Pearl Bonus Game that’s meant to make this game shine, but it offers wins up to only 1,295x your stake. Not nearly enough to justify the base game grind, no matter how charming and sexy the mermaid looks. Buying the bonus game is not too expensive though, and this might be your best option (if it is indeed available in your jurisdiction).


  • Expanded mermaid wild
  • Pick’em bonus game
  • Free spins with 2x multiplier


  • Medium to high volatility and only 1,295x max win potential
