Mermaid's Millions game review

Hidden beneath the waves lies King Neptune’s kingdom; a mysterious hidden world of vast riches, sunken treasure and fantastic sea creatures!

Mermaids Millions is a 5x3 reel, 15 payline undersea fantasy slot featuring vibrant, colorful graphics and two rewarding Bonus Features.

Originally released by Microgaming way back in 2005, Mermaids Millions is a straightforward and accessible game that is still popular with the online slots community today, and regarded as a classic by many players.

As early pioneers in the online gaming industry, Microgaming was one of the first slot developers to include Free Spins, Bonus Features and Progressive Jackpots in their games. Building on the success of 5 reel video slots like Thunderstruck and Tomb Raider, Mermaids Millions was designed to include Free Spins (with a 3x Multiplier on all wins), Free Spin Retriggers, Wild Symbols, and a Pick Bonus, cementing the game’s popularity with a wide spectrum of players.

Mermaid’s Millions is considered a low volatility (variance) game which means that the slot will pay out smaller wins on a frequent basis. This type of game will suit low-risk casual players who enjoy frequent wins and extended play sessions. Although the base game wins are moderate, there is potential for bigger payouts in the Free Spins, especially with the 3x Multiplier on all wins!

Mermaids Millions has a maximum payout of 120 000 coins. The Return to Player (RTP) is calculated at 96.56% which is within the average range for this type of slot.

The betting mechanism in Mermaids Millions is flexible and player-friendly, with betting options that will suit most budgets. The total bet is dependent on the coin size, the number of active paylines and the number of coins played per payline – all these parameters are easily selected and adjusted on the console. The coin size ranges from 0.01 to 1, the number of coins per line ranges from 1 to 5, and 1 to 15 paylines may be selected. A Bet Max option is an easy one-click solution for players who want to play the highest bet of 75 coins per spin.

Let’s take a dive to the depths of the ocean and explore Mermaids Millions in detail!

What symbols are there?

The high symbols are represented by the Mermaid Scatter, King Neptune Wild, Treasure Chest Bonus, Gem Box, Oyster & Pearl, and Seahorse (with those cool sunglasses). The low symbols are represented by card symbols, namely Ace, King, Queen, Jack and Ten.

All Symbols (except for the Scatter) pay a fixed coin value. The Scatter Symbol wins are multiplied by the total bet staked.

The maximum payouts for each symbol (landing 5 of a kind on any active payline at max bet) are as follows:

  • Mermaid Scatter – 400x total bet
  • King Neptune – 7500 coins
  • Treasure Chest – 2500 coins
  • Gem Box – 500 coins
  • Oyster and Pearl – 500 coins
  • Seahorse – 250 coins
  • Ace – 125 coins
  • King – 100 coins
  • Queen – 100 coins
  • Jack – 75 coins
  • Ten – 75 coins

King Neptune is Wild and will substitute for any symbol (except the Scatter and Bonus Symbol). Wild Symbols help to complete winning combinations on any active payline.

Landing 3, 4 or 5 Treasure Chest Bonus Symbols will pay a cash reward AND trigger the Treasure Bonus.

The Mermaid Scatter Symbol wins are multiplied by the total bet, with a decent 400x total bet for 5 Scatters landing on an active payline. Landing 3, 4, or 5 Mermaid Scatters in any order on the reels will trigger the Free Spins Bonus!

What are the bonus features?

The Treasure Bonus is a Pick Bonus triggered by landing 3 or more Treasure Bonus Symbols on an active payline (from left to right). During this bonus, the player is presented with a selection of sunken barrels and treasure chests at the bottom of the ocean floor. Pick any item to reveal a guaranteed cash prize that is added to your payline wins at the end of the bonus game.

The number of picks awarded depends on how many Treasure Chest Bonus Symbols triggered the feature; 3 Symbols awards 3 Picks, 4 Symbols awards 4 Picks, and 5 Symbols awards 5 Picks.

The awesome feature can be triggered in both the Base Game and the Free Spins Bonus.

Free spins in Mermaids Millions

Landing 3 or more Mermaid Scatter symbols anywhere on the reels will award 10 Free Spins in the Free Spins Bonus. This Free Spins Feature is exceptional for two reasons. Firstly, all wins are TRIPLED during Free Spins – that right, a 3x Multiplier is applied to every Free Spin win! Secondly, Free Spins can be re-triggered at any time. Landing 3 or more Mermaid scatters will add an additional 10 Free Spins to your Free Spins Bonus, so keep an eye out for that adorable but shy Mermaid.

What is the jackpot (max win)?

Mermaid Millions offers a maximum fixed jackpot of 120 000 coins on the maximum bet of 75 coins. Remember this is a low volatility (variance) game, so players can expect frequent low paying wins. However, there is some great win potential in the Free Spins Bonus with the 3x Multiplier.

SlotCatalog verdict

Compared to the sophisticated and carefully engineered games we see today, Mermaids Millions is a somewhat dated, but uncomplicated classic that still has the charm and win potential to keep players spinning. The graphics are cheerful and have a retro appeal, and the regular wins and excellent Bonus Features are reason enough to give this game a good few spins!


  • 3x Multiplier in Free Spins
  • Free Spins re-triggers
  • Great betting / wager options to suit all players and budgets


  • Low Variance may not suit high rollers looking for those Big Wins
  • Dated (but still cool somehow!)
