Software developers like Reel Kingdom and Blueprint Gaming have gone to great lengths to create a successful fishing series, but has 4ThePlayer pushed the boat out far enough in this release? Let’s play on and find out!

Base Game & Features
4 Fantastic Fish Amazon Adventure is a highly volatile 6-reel, 4-row Video Slot with 4,096 ways to win and a wide selection of bet sizes between £.€0.10 and £.€80 per spin. Other noteworthy attributes include an overall RTP of 94% and a solid max win capacity of 11,340x your bet.
Wins occur when 2-6 identical symbols land from left to right on adjacent reels, starting from reel 1. Where applicable, each high and low-paying symbol from the paytable offers a fixed payout between 0.2x and 10x your bet. In addition, Wild symbols appear on all reels (except reels 1 & 2 simultaneously), substituting for every paytable symbol except Scatters.
Money Ways & Big Game Prizes
Individual Piranha symbols can appear on all 6 reels with a random cash prize between 0.1x and 45x your bet. When 3 or more Piranha symbols create a winning sequence, the total value of each cash prize is awarded.
In addition to Piranha symbols, the game also hosts 4 Big Game Prizes: Big (50x), Super (200x), Mega (1,000x), and Ultra (10,000x). Big Game Prizes appear only on reel 6 and are awarded when part of a Piranha way win.
Piranha Frenzy & Giant Anaconda
The Piranha Frenzy and Giant Anaconda features utilise a similar functionality to the Giant Squid found in the original 4 Fantastic Fish release. During any spin, Piranha symbols can appear on the reels to award the following functions:
- Base Game: Swims onto the reels to create or improve existing wins using Piranha symbols
- Amazon Respins: Swims sideways to lock onto open reels
Another interesting addition to the game is the Giant Anaconda Feature, which can appear during any spin to award the following outcome:
- Base Game: Swaps symbols to create or improve a Piranha win
- Amazon Respins: Moves a Piranha symbol from a closed reel to an open one and locks it in place

Big Reel Portrait Mode
When playing 4 Fantastic Fish Amazon Adventure on a mobile device, you can choose to play in either Classic or Big Reel Portrait mode. In big reels mode, the reels are stacked on top of each other, spinning from right to left and paying top to bottom. Please note that payouts and game features remain unchanged.

4 Fantastic Fish Amazon Adventure Slot Free Spins
Landing 3 or more Scatters across the 6 reels in the base game triggers the Amazon Respins feature, awarding 3 Respins. Each reel a Scatter lands on will remain open, whilst all others are closed. In addition, all Piranha symbols that hit on the triggering spin will lock onto the reels, regardless of whether they are on an open or closed reel.
In this round, all positions will spin in a bid to reveal new Piranha symbols. When a new Piranha symbol appears on an open reel, it locks into position and awards its Cash Prize. Please note that Piranha symbols that land on closed reels will not be locked. If a Respin Scatter lands on a closed reel, it will instantly open for subsequent Respins. Each time a new Piranha symbol lands, the Respins meter is reset.
When an open reel is completely filled with Piranha symbols, a Gator will swim up and collect the total value of Cash Prizes on that reel. The total prize is multiplied by x2 and held in the top reel position, leaving room for additional Piranha symbols to land.

Lost City Pick-A-Win Bonus
Landing 3, 4, or 5 Pick Scatters on any reel in the base game triggers the Lost City Pick-A-Win Bonus, awarding 3, 4, or 5 Picks, respectively.
In this bonus, a series of Gold Temples will be presented. Behind each temple is a random Cash Prize between 25x and 11,220x your bet. All you need to do is select a number of Gold Temples, corresponding to your number of picks, until no more picks remain. At the end of the bonus, the total of all cash prizes is awarded.

Our Honest Verdict
These days, almost every new release you come across continues to bulk up the online fishing slot genre, with Reel Kingdom’s Big Bass Bonanza series making up a huge chunk of it. When 4ThePlayer first introduced 4 Fantastic Fish, we were a little apprehensive. For the most part, each new fishing slot had followed the guidelines of every Big Bass Bonanza slot on the market, that is, until 4ThePlayer whipped up something unique and refreshing.
Several years and multiple instalments later, we find ourselves testing the waters of 4 Fantastic Fish Amazon Adventure, and we once again commend it for its difference from your run-of-the-mill fishing slot. It has the normal 4 Fantastic Fish Features, coupled with a nod to the adventurous 3 Secret Cities. We think 4 Fantastic Fish is in many ways just as good as Big Bass Bonanza, if not better in some regards. It’s a competitive genre, and slots don’t always get the recognition they deserve, but we’d recommend this and others in the series to anyone with an affinity for casting their reels.
It’s not innovation personified to the level that some other slots are. You wouldn’t play it and think 4ThePlayer has reinvented the reel, but it was never meant to. It continues to be appealing to us, but we can understand why it may not be everyone’s cup of tea. After all, many cast aside fishing slots altogether, favouring the wilder, boundary-pushing titles from the likes of providers that completely flip the traditional slot formula on its head.
