Megaquarium is one of RTG’s slot machines and a game where the player appears to be getting an aquarium or tropical fish theme. The title refers to a huge aquarium, so the action doesn’t take place in the ocean, even though the graphics are very rich and suggest that kind of environment.

In Megaquarium, you get plenty of space to play in, with 5x3 reels sporting no less than 50 fixed lines for you. There are big payouts to be had, even up to $12,500 during some features. When you’re looking at features, those include wild symbols, multipliers, scatters and more than one type of free spins.

Betting and Prizes

You get to play with 50 active lines each round, deciding only on the total amount that will be used for them. It starts at a minimum of just $0.50 and it can go even up to $12.50. The range of a line bet is between $0.01 and $0.25.

The slot can pay reasonably well, offering up to 10,000x rewards with the wild doubling wins, or $2,500 cash. There are multipliers of up to 5x during some free spins, so at that point you’re looking to rewards of up to $12,500. Progressive jackpots are available in the game, and they might do better than you can with the regular payouts.

Megaquarium Slot Features

The Clown Fish is a major feature in this slot machine, as a symbol that you can use to replace others. The downside is that you get it only on reel 2 or 4, but at least when it is part of a new combination it gets to double the value of the payout. It will not be of any use to you if you need help with one of the bonus symbols. Every other symbol is fair game for it and it can be part of its combo.

The Free Games logo is the one you want, to trigger the slot’s 7 free spins. There will be a requirement to have that logo on the reels 1 and 5 at the same time though, in order to meet the requirements. The free games have doubled payouts for the duration. They also have Bonus Games symbols, added to the 1st, 2nd and 3rd reels, but only during the 7th free spin. If you get those three symbols on all three reels, and during the 7th spin, then the feature is extended.

There are 3 additional spins offered at this point, where the 5th reel is made up only of Clown Fish wilds. The last spin (the 10th round by now), will sport additional Super Games symbols for the first three reels. Once again, if you get them all to appear, the feature will be extended. On top of that, after each bonus game you get a random payout of 2x to 100x your bet.

Now that you got to the Super Games, you will once again have 3 rounds to play for free. The multiplier goes up to 5x here, and will be applied to all wins coming from this point forward. The 13th spin of the feature will get Mega Games logos on the first three reels. With the three visible during that last round, you will extend the feature again. You also get paid 3x to 200x your bet after each Super Game.

Finally, we get to the 3 Extra Free Games, the final stage of this long feature. In it, there are Clown Fish wilds covering all positions on the last two reels. The 3rd reel gets Extra Game symbols. Rewards of up to 500x your bet are given after each round.

Theme & Design

The theme is inspired by a huge aquarium, so you will see on the reels images of various logos, of clown fish, treasure chests, signs, vegetation, lobsters, crabs and different tropical fish. It’s a decent looking design, overall.


The game’s major point of attraction comes from its features, even though its look is also a pretty good one.
