Our verdict on Big Bass Amazon Xtreme
We actually spent more time than we’d have thought on this slot. Once we were given a taste of its free spins feature, we kept coming back for more. Being a high volatility game, it wasn’t easy to trigger this bonus feature, but it was totally worth it. The increasing levels you can reach in the bonus are super exciting, with the Fisherman wild multipliers and 10 new free spins unlocking quite frequently.
The base game is pretty similar to the other Big Bass games, although some random features help keep things fresh after some long sessions. If you enjoy high volatility games, go and try this slot: you won’t be disappointed!

5 reasons to play Big Bass Amazon Xtreme
We’ve played Big Bass Amazon Xtreme for an extensive amount of time and had a lot of fun with it. Here are some of the reasons why we found it enjoyable:
- Fisherman Wild during Free Spins: If you’re lucky enough to unlock free spins, you might land some Fisherman wilds on your reels. They’ll collect all the money symbols available, creating some big wins. If you can reach the higher levels of these bonus rounds, the wild will even multiply the values he collects.
- Start your Free Spins with Extra Features: When you get to the bonus rounds, you’ll get to select pots that can give you some extra features for your free spins. You’ll be able to continue picking pots until you get a boot, so features can stack up quite nicely.
- Win More and More Free Spins: Every fourth wild you land during your bonus rounds gives you 10 more free spins, until you reach the highest level of the bonus (where Fishermen multiply money symbols by 50). In total, you can unlock a total of 80 spins (without counting the ones you might get from the pots).
- Random Collection during Base Game: During the base rounds, each fish symbol comes with a value. This value can be collected at random during one of your spins, which is always an exciting surprise!
- 10,000x Max Payout: High volatility needs to come with the potential for some big rewards. The max payout of 10,000x is quite high, even though some other high volatility slots might offer bigger ones. Odds are, you won’t land this payout, but the rewards available during free spins are absolutely worth your while, especially if you’re willing to spend some time on the game.

How to play the Big Bass Amazon Xtreme Slot?
Big Bass Amazon Xtreme has two distinct parts: the base game, a classic 5×3 grid with 10 paylines that includes randomly triggered features; and the free spins, where things get really exciting. Before diving into what makes it special, let’s review how a spin in the base game goes.
Step-by-Step Gameplay
- Launch Big Bass Amazon Xtreme.
- Place your bets, from £0.10 to £250.
- Spin the reels and see if you get any winning combo.
- If you’ve landed at least 3 Scatters, you’ll trigger 10 free spins.
- Once your wins have been collected, or your free spins are done, the round ends.
- Adjust your bet if necessary, and spin again!

Symbols & Bonus Features
Symbols in Big Bass Amazon Xtreme are similar to the ones you can find in Big Bass Bonanza (at least theme-wise, visuals have been updated since then): most of the paying symbols are cards (from 10 to A) or fishing gear, although a toucan made its way into the roster (it does take place in the Amazon forest!). The real fun starts with the fish money symbols. Each fish that lands on the reels comes with a value that goes from 0.2x to 1,000x your bet. After any spin during the base game, a random feature can trigger and collect values from these symbols.
Then we have the Scatter symbols. Landing at least 3 of these will trigger 10 free spins. Before playing those, you’ll be taken to a temple and will need to select pots in order to win some bonuses. In these pots, you might find a few things:
- More free spins;
- Already collected Fishermen Wilds, which will help you get to the higher levels of the bonus rounds;
- Guaranteed Fish, that’ll make sure you land at least one fish symbol per free spin;
- A bonus that’ll remove the lowest fish from your reels, ensuring higher payouts;
- A boot, which will end the selection process and take you to your spins.

Once you get to the actual free rounds, you’ll see a ladder on top of your reels, with Fishermen and more free spins. That’s where this slot really comes to life: every time a Fisherman Wild lands on the reels during the bonus game, it collects all values on the grid, but also fills up the ladder. For each four wilds you get, the ladder reaches a new level: 10 more free spins, and wilds that now multiply the values they collect. Reaching the highest level and its 50x multipliers won’t be easy, but the payouts could be enormous.

Visuals and theme
Big Bass Amazon Xtreme transports players into a lush, animated world set deep in the Amazon rainforest. Visuals in the Big Bass series have come a long way, from the fixed background in Bonanza to the lively forest and waters we’ve got now. Once again, the reels are submerged in water, this time being the Amazon river. Above water, the iconic bearded fisherman from the series naps in his wooden boat, ready to barge in when the Free Spins hit.
Colours are sharp, animations are fluid, and the overall aesthetic feels more polished and vibrant than ever. We even get to experience a new scene, right before free spins, when we’re taken into a temple, with soft lighting and subtle animations. Overall, this just feels like the modern Big Bass entry we deserve, and we can’t wait to see what the next one will look like.
Big Bass Amazon Xtreme’ RTP and volatility
Big Bass Amazon Xtreme offers a high-risk, high-reward experience that’s mostly made for risk-takers. The default RTP is a classic 96.07%, which is right in the average for online slots. The game’s volatility is very high (rated 5/5 by Pragmatic Play), meaning long stretches without significant wins are possible, but the rewards, when they land, might just be worth the wait.
During our long testing session, we observed that triggering the free spins feature could prove difficult (we got it approximately once in every 150 spins). With a 10,000× max win, and high payouts during bonus rounds, this slot’s potential is definitely attractive, although players will likely need to put their patience to the test in order to get a taste of it.
Play Big Bass Amazon Xtreme on Mobile
Big Bass Amazon Xtreme is fully optimised for mobile play, delivering the same vibrant visuals and feature-packed gameplay whether you’re spinning on a smartphone or tablet. Thanks to HTML5 technology, the slot loaded quickly on our iPhone 15.
Pragmatic Play always made sure their games were as fun on smaller devices as they are on desktop, and it shows. The user interface is intuitive and responsive, with touch-friendly controls that make spins or autoplay simple to execute. Every feature works perfectly, from the free spins to the temple where you can pick pots.
