4 Fantastic Fish Amazon Adventure Slot RTP, Details & Wager Limits

The reels in the 4 Fantastic Fish Amazon Adventure slot are almost as long as the name. It’s a 6×4 grid, and pays all ways like Megaways slots. Wins are created with at least 3 matching symbols on a payline, matching standard online slots gameplay. The three highest paying symbols only need 2 on a line, making them slightly more valuable.

You can wager between 20p and £80 in the 4 Fantastic Fish Amazon Adventure slot game. It’s a solid stake range but might exclude the highest and lowest budget players. All controls are on the right-hand side, with stake controls above and below the spin button. It caused me a bit of confusion in the free slots version, as it’s not well labelled. You can set up an autoplay, but it’s unavailable to UK online casino users.

There’s an RTP of 94%, which is a bit below the industry standard. Unfortunately, like many new slots online, it also has an RTP range. It can drop to 90.5%, so you’ve got to check UK online casinos to make sure you play at the best rate. It has a high volatility, and it felt at that level when I put together my 4 Fantastic Fish Amazon Adventure review.

The 4 Fantastic Fish Amazon Adventure max win is 11,340x your stake. It’s not as high as the top jackpot slots, but it’s still a competitive payout. The picking bonus round is where the biggest wins lie. I managed just over 300x my stake when playing the 4 Fantastic Fish Amazon Adventure demo.

4 Fantastic Fish Amazon Adventure Theme—A Classic Style with Cartoon Visuals

4-fantastic-fish-amazon-adventure-slot-base-game

I like the theme in 4 Fantastic Fish Amazon Adventure. It treads a fine line between classic styles and looking dated. It’s a challenge that 4ThePlayer has stepped up to superbly. All symbols have a cartoon style, which matches everything very well. It has lots of colour, so it creates a bright environment.

The sounds are equally as impressive. With a drum beat underpinning what 4 Fantastic Fish Amazon Adventure casinos pump out, it takes you straight into the Amazon. It also plays a different tune when you enter the bonus rounds, which is more upbeat and exciting. Overall, this is a fun-looking game that offers a new take on a classic theme.

4 Fantastic Fish Amazon Adventure Mobile Slot

The 4 Fantastic Fish Amazon Adventure mobile slot is one of the best designs I have come across. You can choose how it’s laid out, giving you control of the screen. It means you get the layout that’s right for you, based on your device. If you’re a mobile casino player, this is the standard you should always look for.

4 Fantastic Fish Amazon Adventure Bonus Features

There’s an excellent selection of 4 Fantastic Fish Amazon Adventure bonus features. They cover the base game and multiple bonus rounds, making for exciting gameplay.

Piranha Prizes

The Piranha symbols can land on paylines, awarding higher values from left to right. If you complete a payline of Piranha symbols, there’s a chance you’ll land the jackpot fish, which goes as high as 10,000x your stake, on the sixth reel. They only pay out if they activate a payline.

Giant Anaconda (Random Features)

4-fantastic-fish-amazon-adventure-slot-anaconda-feature

At any point in the game, the Piranha Frenzy can trigger. It will either create Piranhas or increase their value. If it triggers in the Respin round, it will move them from locked positions to open ones.

The Anaconda can land, and it works in a similar fashion. It moves Piranha symbols around to help create wins. During the Respin, it will shift locked Piranhas to open reels.

Amazon Respins

4-fantastic-fish-amazon-adventure-slot-respins

If you land 3 or more scatters, it triggers the Respin feature. The reels where the scatters landed are open during the round, but any without a scatter start off locked. You get 3 respins to begin, and every time you land a Piranha or scatter, it resets your total. The round continues until you run out of respins.

If you fill a reel completely, a gator appears, eating all the fish, leaving a skeleton in the top position, doubling the value, and opening new spaces for more fish. It’s an excellent addition to the round, which creates more excitement. However, it can’t eat the 10,000x Piranha, so it will just leave that in place. If you land a scatter on a locked reel, it opens up that reel.

Lost City Pick-A-Win

If you land 3 or more temple scatters, it triggers a picking round. Here, you get the same number of picks as scatters that start the feature. The temples can be worth between 5 and 10,000x your stake.

Bonus Buy (Unavailable in the UK)

You can pay 30x your stake to initiate a spin that guarantees Piranha Frenzy will trigger. If you want to jump right to the bonus rounds, you can pay 75x for the Respins or 150x for Temple Pick-A-Win.

4 Fantastic Fish Amazon Adventure Verdict: Fun Gameplay, a Nice Theme, and a Solid Top Win

4.5/5

4 Fantastic Fish Amazon Adventure Slot

There are many good things in 4 Fantastic Fish Amazon Adventure, but it’s not quite at the top level. The base game sometimes drags a bit, and the name of the game is a bit too long, which are the main downsides.

Pros
  • Several features
  • Base game bonuses
  • Max win of 11,340x
Cons
  • High volatility can make the base game drag
  • The name is ludicrous
  • Low RTP

There’s some good stuff in this game; it has many features, including base game random bonuses, which help keep things interesting. It’s vital that they’re there because it can drag due to the high volatility. I feel like the game’s title is to try and get some search engine juice from the new Fantastic Four film, which is worth it if it works.

Overall, it’s fine. I just think something is missing here. The base game is too dry at times, and the max win isn’t high enough to deal with that. It’s certainly a well-above-average title, but it doesn’t have that spark to make it an elite game. It’s worth trying out, and is worth its final score, but there are better games on the market.

If you want a game that has that elusive x-factor, then Razor Returns from Push Gaming is the title for you. It offers incredible graphics, wild features, and up to 100,000x your stake as a top win. Another jungle-themed slot to try is Playtech’s Gold Pile: Orangutan—it offers a stakes range of up to £500 and unlimited free spins. Stay with the 4ThePlayer series, and go for the 4 Fantastic Fish Gold™.
