Game Design

Theme and Graphics

Under the sea we go, with this simple slot from Microgaming. The dark blue background of Mermaids Millions features bubbles floating slowly to the top. These images, combined with the bubbling sounds, produce a very calming effect.

Mermaids Millions is a straightforward game. There isn't much in the way of fancy graphics, but it gets its point across. The layout is practical and intuitive. On the right side are the options to control sounds, the information about the slot itself and the help section. Under that menu, you'll find the auto spin, spin, fast play and betting options.

Sound and Experience

The first noticeable thing is the lack of background music. Instead, the soothing sound of bubbles plays throughout the game, with small jingles playing when you hit the spin button.

When you hit two or more scatters, the mermaid chuckles as if she's enjoying this as much as you are. If you're lucky enough to have King Neptune’s wild symbol in a pay combination, the mythological God gives you a cheeky wink.

Mobile Compatibility

Mermaids Millions is optimised for mobile gameplay. It loads a little slower on a mobile device, but that doesn't impact the game. The menu options can be found on the bottom of the screen in the mobile versions.

There’s no option to download the game. A few years ago that might have been a deal-breaker, but not anymore. The games are available through a browser on any mobile device; no download of adobe flash is necessary.

Bonus features

Game Symbols

The symbols in the Mermaids Millions slot fits beautifully with the aquatic aesthetic. Even the 10-A symbols have underwater themes. The ten wears a starfish, and the J is hiding a sneaky octopus. The Q is wearing a string of pearls. Even the K gets in on the action, holding up King Neptune's trident. An adorable lobster holds the A.

The God of the sea, King Neptune, doubles as a wild symbol. It can replace any symbol other than scatters and treasure chests. Other symbols include seahorses, oysters and jewellery boxes.

Three or more treasure chests unlock the bonus round. Landing on more chests rewards you with higher bonuses. The scatter symbol features the beautiful mermaid. Two or more scatters pays out your total stake two times over. The scatters don't need to be in a winning payline to payout.

Bonus Rounds & Free Spins

Three or more treasure chests trigger the bonus round. The bonus round occurs on the ocean floor, with various sunken treasures half-buried in the sand. You pick the number of rewards that correspond with the number of treasure chests you land on in the main game. These rewards could be anything from a few pounds, to a few hundred pounds.

Scatter pays out if you hit two or more of the symbols. Three or more scatters earn bonus spins! All of the bonus spins are worth triple with the multiplier. It's possible to retrigger the free spins as well; so, in theory, you could play a lot of free spins!

Mermaids Millions Jackpot

Some slots feature progressive jackpots that grow larger every time the game doesn't payout. It's exciting and exhilarating to hit the jackpot, but this isn't a feature of all slots.

There isn't a specific jackpot on Mermaids Millions. With the max bet in play, you could win up to £37,500 in the main game. The amounts in the bonus round vary, depending on how many treasure chests you win. We uncovered a prize of £900 in the bonus round.

Mermaids Millions Hits & Misses

  • Pros

Mermaids Millions is a brilliant game for those looking to relax while they spin. The soothing sounds and visuals of bubbles in the background is both calming and relaxing. The game is a little on the dull side, but the giggles from the mermaid scatters can be rewarding when they payout.
