Big Bass Amazon Xtreme Slot (Pragmatic Play)

The Big Bass Amazon Xtreme slot takes place on 5 reels, 3 rows and 10 paylines (which are fixed). Winning combinations are traditional in that you need 3 or more identical symbols appearing from left to right across any of the 10 paylines.

Beginning from the leftmost reel (i.e. reel 1), 3 or more are required for the majority of symbols with 2 or more for the high-value fishing float symbol. Only the highest win per payline will be awarded.

You can play Big Bass Amazon Xtreme from as little as 10p a spin to as much as £250 per spin. The max bet of £250 may be lower at some slot websites though. If you want to change your bet, there are plus and/or minus buttons below the reels on the desktop version or by pressing the Coins icon on mobile or tablet devices.

Non-UK players have a few more gameplay options. First up is Autoplay which allows from 10 to 1,000 auto spins. For quicker spin speed, use Quick or Turbo Spin modes.

The Big Bass Amazon Xtreme RTP rate is 96.07%. Whilst higher than the online slot game average of 96%, Pragmatic Play has produced 95.08% and 94.05% RTP versions. The chances are that most UK slot sites will offer the medium or lower RTP setting to check in the Paytable before playing.

Very high volatility (5/5), the hit frequency rate is 11.76% meaning a win will land in the base game every 8.5 spins on average. Your chances of triggering the Free Spins feature are 1 in 148.43 spins on average too.

Lastly, the Big Bass Amazon Xtreme slot benefits from 10,000 times bet max wins. With the bigger wins coming in the free spins, the max win probability is 1 in 14,321,518 spins (14.3 million). Winning 1,000 times your total bet or higher will occur every 28,445 spins (on average).

With a fishing theme, the Big Bass Amazon Xtreme slot was released by Pragmatic Play on the 19^th of June 2023. Following a long line of Big Bass slot games, you get to fish the longest river in this world (i.e. the Amazon River).

Using similar graphics and imagery as other games in the series, this fishing trip is set in the heart of the Amazon and has cartoon-style visuals. Colourful and bright, the soundtrack is upbeat and jolly. With the reels set just under the water, you’ll see the fisherman sleeping in his boat.

On the reels, there are low-value A, K, Q, J and 10 paylines. The higher-value symbols include backpacks, fishing rods, toucans and fishing floats. The fishing float symbol pays the most with a 200 times bet payout for 5 in combination. A screen full of fishing floats pays 2,000 times your total bet.

Big Bass Amazon Xtreme comes with a Fisherman Wild symbol which only appears during the free spins. It substitutes for all paying symbols. Then there is a Fish Scatter which is key to triggering the Free Spins feature. Finally, there are Money symbols which contain bet multiplier values up to 1,000 times your total bet. I will go into more detail in the section below about how they affect the action. Below is a list of all symbol payouts and functions:

• Q/J/10: 3, 4 or 5 = 0.2, 1 or 5 x bet
• A/K: 3, 4 or 5 = 0.2, 2.5 or 10 x bet
• Fishing Rod/Backpack: 3, 4 or 5 = 2, 10 or 50 x bet 
• Toucan: 3, 4 or 5 = 3, 15 or 100 x bet
• Fishing Float: 2, 3, 4 or 5 = 0.5, 5, 20 or 200 x bet
• Fisherman Wild: Substitutes + collects Money symbols during free spins
• Money: Worth up to 1,000 x bet + collected in base game randomly & during free spins
• Hooked Bass Scatter: 3+ triggers Free Spins feature

Big Bass Amazon Xtreme Mobile

Created with HTML5 technology, the Big Bass Amazon Xtreme slot can be played on laptop, PC, tablet and mobile devices. Adapting to whatever device you use, it’s compatible with iOS and Android smartphones making it perfect to play on the go. The 5x3 reel setup is perfect to play at mobile casino sites too.

Big Bass Amazon Xtreme has 7 bonus features. In the base game, Money symbols are randomly collected and awarded with a multiplier up to 50x applying. All about the Free Spins feature, Fisherman Wilds collect Money symbols and are added to the progression meter. This will give you extra free spins and increase the Money symbols multiplier up to 50x. There’s also a couple of random features to help you win more during the free spins.

Money Symbols

As with other games in the series, you’ll see Money symbols on the reels which are worth between 0.2 and 1,000 times your total bet.

The Money Symbols feature will be randomly triggered in the base game which sees all Money symbol values collected and won. When this happens, a random multiplier ranging between 1x and 50x will be applied to the total value collected from all Money symbols. Below are the possible Money symbol and multiplier values:

• Money symbols: 0.2, 0.5, 1, 2, 3, 4, 5, 10, 15, 20, 25, 50, 200, 250, 333, 500 or 1,000 x bet
• Multiplier: 1x, 2x, 3x, 4x, 5x, 10x, 20x, 30x, 40x or 50x

Free Spins

The Big Bass Amazon Xtreme slot game focuses on the Free Spins feature. To play it, you need to land 3 or more Hooked Bass Scatter anywhere during a base game spin.

If you land 2 Hooked Bass Scatters, there is a chance another scatter will be brought onto the reels with the Random feature:

• If the Hooked Bass Scatters can move down 1 position without leaving the reels, a respin is awarded where the reels with scatters move 1 position down and the reels without scatters respin.
• A crocodile can appear and change 1 symbol on the screen into a Hooked Bass Scatter.

Once in, 10 free spins will be awarded. If you trigger the feature with 4 or 5 Hooked Bass Scatters, you will begin the picking section with 1 or 2 boot items revealed respectively. You then pick objects to uncover modifiers which are in place during the feature. Simply carry on picking until you reveal a boot which then starts the feature. Below are the modifiers you can uncover:

• More Free Spins: 1, 2 or 3 extra free spins can be won (for up to 6 extra free spins in total)
• Guaranteed Fish: 1, 2 or 3 guaranteed Money symbols will appear on every free spin
• Already Collected Fisherman Wilds: Up to 3 Fisherman Wilds will contribute to the progression meter which makes it easier to retrigger the feature
• Remove Lowest Fish: Up 2 low-value Money symbols are removed from the reels (2x and then 5x Money symbols)

Look out for the Fisherman Wild symbol appearing during the feature as he collects all Money symbol values appearing on the same free spin. Every 4^th Fisherman Wild collected will retrigger the feature which awards 10 extra free spins and increases the multiplier for Money symbols collected. There are 8 levels with the multiplier increasing up to 50x:

With a total of 80 free spins to be won, no more retriggers are available once you reach level 8. The feature also comes with a few random extras to help you win. They are as follows:

• Bazooka feature: If a Fisherman Wild appears with no Money symbols on the reels, Money symbols can be added randomly. A water animation is initiated and changes all symbols into other symbols.
• Hook feature: If no Money or Fisherman Wild symbols land, a hook can randomly pull up a random reel to add Fisherman Wilds and Money symbols onto the reels.

Ante Bet 

As with many Pragmatic Play slot games, there is an Ante Bet feature that is optional. Your bet amount increases by 50% (so a 10p spin would be a 15p spin) but in return your chances of landing Hooked Bass Scatters increase. The RTP is lower only fractionally at 96.06% (for the 96.07% RTP version).

Buy Free Spins

Available to non-UK players, there is an optional Buy Free Spins feature. For a cost of 100 times your total bet, you can buy your way directly into the Free Spins feature. Randomly awarding 3, 4 or 5 Hooked Bass Scatters, the RTP remains the same at 96.07% (for the highest RTP setting).

Big Bass Amazon Xtreme Slot

Rating: 4.3/5

Big Bass Amazon Xtreme comes with Money symbols/multipliers and Fisherman Wilds in the free spins which collect Money symbols and award extra free spins and multipliers for wins up to 10,000 x bet.

Chris Taylor

With the likes of Big Bass Splash and Big Bass Bonanza being so popular, the Big Bass Amazon Xtreme slot has a lot to live up to. The setting is the Amazon River and the slight change graphically is welcome and gives the game its own identity in a series that is by en large nearly identical visually.

When it comes to the gameplay, there are Money symbols worth up to 1,000 x bet which can be collected randomly in the base game. Pragmatic Play has added a random multiplier up to 50x which is then applied to Money symbol values.

The Free Spins feature follows a similar pattern to previous Big Bass series releases where picks can give you guaranteed Money symbols on each free spin, up to 6 additional free spins, up to 2 of the lowest value Money symbols removed from play and up to 3 Fisherman Wilds added to the progression meter.

The latter is my favourite as it increases your chances of a retrigger. This in turn gives you more free spins and increases the multiplier applied to Money symbol wins up to 50x. If you manage to retrigger enough times, you’ll play a total of 80 free spins with a 50x multiplier! Therefore, Fisherman Wilds are key to winning big in Big Bass Amazon Xtreme.

In Big Bass Splash, you have the chance to begin on level 2 (with a 2x multiplier) which has been removed in this game. The randomly-triggered Dynamite feature in the free spins has also been discarded in this release.

With 10,000 times bet max wins, Big Bass Amazon Xtreme is one of the highest-paying slots in the series. Only Big Bass Hold & Spinner Megaways offers bigger win potential (20,000 x bet max wins). In summary, it’s a welcome addition to the Big Bass slots series which takes it to another level in my opinion.

If you prefer horse racing, Big Bass Day at the Races is the same slot game but takes you on a day out to the racecourse instead of the Amazon River.
