Megaquarium Slot Review

Megaquarium slot takes players deep to the bottom of the aquarium for free spins and progressive jackpot prizes. Know more about the game in this review.

Megaquarium: An Aquarium-Themed Slot for Free Spins Lovers

Megaquarium slot is one of the games that have themes focusing on fish. Some online slots will usually bring you to the bottom of the ocean, but this title will bring you to the bottom of the aquarium.

The slot game is one of the few progressive titles developed by RealTime Gaming. Here, you will spin your way to multiple free spin bonuses, giving you several chances to bring home rewards. Know what to expect from this game by reading this Megaquarium slot review.

Graphics and Sounds

The graphics of the slot game is not its strongest point, but the background is colorful and animated enough to make you feel that you are underwater. The reels are alive with elements you will find in aquariums. There are corals, hermit crabs, treasure chests, and more.

Meanwhile, the upbeat music in the background is a good fit for the game. The aquarium or the underwater may not be the calmest place in the world, but that does not mean your spinning sessions should be quiet.



The game uses the classic 5×3 structure with 50 paylines that pay from left to right. All paylines are fixed, costing you 0.05 to 250 coins per spin. There is an Auto Play function that lets you spin the reels automatically and up to 100 times. And if you want to make all reels spin faster, use the Speed Button.

Bonuses and Special Features

There are only three special features to look out for when playing Megaquarium. Know more about them below:

Wild Symbol

The Clownfish stands as the game’s Wild, substituting symbols on a winning payline. Plus, the icon doubles the amount of all winning combos. So if you pair the Clownfish with the highest-paying symbol, the highest prize you could win is 10,000 coins.

Free Spins

Land the Free Games icons on Reels 1, 5, and 7, and you will earn seven free spins. For every win you land during this round, your winnings double.

The best part about this mini-game is that you have a chance to get more free spins. Watch out for the following symbols as they appear during each free round:

  • Bonus Games: These icons appear on Reels 1, 2, and 3 on the seventh free spin during Free Games. This grants you a 2x multiplier on all winnings. Plus, the Clownfish will populate Reel 5 to double more winning combos. And a random prize of 2x to 100x will be awarded at the end of the round.
  • Super Games: These symbols land on Reels 1, 2, and 3 during the last Bonus Games spin. This will trigger three more free games in which your multiplier increases to 5x. Plus, you will get a random multiplier from 3x to 200x.
  • Mega Games: These icons appear on Reels 1, 2, and 3 during the last Super Games spin. This will give you three more free spins and a random multiplier of 5 to 500x at the end of the round.

The Free Spins bonus may be hard to wrap your head around at first, especially if it is your first time playing the game. Still, once you get the hang of Megaquarium, you will be pleased to have a chance to win 500 times your bet.

Progressive Jackpots

Like many progressive slot games, Megaquarium has a random Minor and Major jackpot that you can win at the end of any spin. Even better is that you can this jackpot prize to your other wins in the main game.

While you will play Megaquarium for the progressive jackpots, you will find yourself staying for the free spins. There may be only up to 16 free spins for you to earn, but the multipliers are high. If you are lucky, you could end up taking home 500 times your bet.
