What Our Reviewer Says ...

"The most exciting Big Bass game to date, stacked with thrilling modifiers, multipliers and progressive features"

Overall Score: 8.8

Theme & Design

Our Score 9

Amazon Xtreme is the most interesting of all the Big Bass slots in design terms. Pragmatic Play are taking you right into the heart of the Amazon forests with rich, dense jungle all around, a sleepy fishermen on a little wooden boat and the bubbling river beneath where the reel set sits. In the background a cheerful tropical tune plays. The same illustrative style is used as you find in the previous Big Bass games, including the symbols which are all bright and cheery. Overall the vibe is fun and upbeat and the style is rich and immersive.

RTP and Variance

Our Score 8

What is RTP?

RTP (Return to Player) refers to the amount a game will pay out in cash prizes expressed as a percentage of all the money wagered on that game. For example, a 96% RTP means a game will pay out £96 for every £100 wagered. This is an average number and will vary from one session to the next.  Read more here.

What is Variance?

Variance refers to how far a game will deviate from its RTP over time. High variance games deviate a lot and produce uneven win distributions and unexpected windfalls. Low variance games provide a more stable and even distribution of wins. Read more here.

Big Bass Amazon Xtreme slot has 3 available RTP settings – 96.07%, 95.08% or 94.05%. Which you play at will be at the discretion of your casino. We verified the RTP at five UK slot sites to see which setting they had chosen. This is what we found:

Not all sites will run Big Bass Bonanza Amazon Xtreme at optimum level. We recommend playing at MrQ, Vegasland or Betfred Games which have chosen the top 96.07% setting.

Like other games in the Big Bass Bonanza series, Amazon Xtreme is a highly volatile slot so it can burn through your balance quickly. We recommend that you choose a low stake level to avoid zeroing-out too quickly.

Maximum Win

Our Score 8

What Is Maximum Win?

Maximum win refers to the maximum amount a player can win from one spin. It is expressed as a multiple of the stake. For example, where the maximum win is 100,000x, from a £1 stake, the maximum win would be £100,000.  

The maximum payout in Amazon Xtreme is 10,000x. This is the same as the recent Hold and Spinner but better than others in the series like the original Big Bass Bonanza or Christmas Big Bass Bonanza (max win 2,100x).

Symbols and Paytable

Our Score 9

Big Bass Bonanza is a straight-forward 5 reel and 3 row slot with a win ways mechanic. That means, wins are triggered by landing 3 or more identical symbols on adjacent reels, regardless of the row they land on, from left to right starting at the left-most reel.

Big Bass Amazon Extreme Paytable
There is good value throughout the paytable

There is really good value in the paytable here across 9 different symbols. Starting with the low payers which are 10 through to Ace, they pay from 0.2x for 3 10s up to 10x for 5 Aces. Premiums are the nicely drawn backpack, rod and line, bird and fishing float. They pay from 2x for 3 backpacks up to 200x for 5 floats.

There is also a wild, represented by the fisherman himself, which will substitute in to complete winlines, and a scatter that is required to unlock the free spins round.

Features and Gameplay

Our Score 10

Enable Ante Bet For Better Chances of Landing Free Spins

Before we get started on the main action, consider the Ante Bet Feature. This increases your current bet size by 50%. If you were betting £1, you’ll now be betting £1.50. For this increased wager you get more scatters dropped onto the reels which gives you a better chance of hitting the free spins round, theoretically.

And as we shall see, the free spins round is what this game is all about.

Collect Fish Money Symbols

Throughout the base game and bonus rounds you should look out for the fish symbols that drop onto the reels displaying a money value from 0.2x right up to 1,000x. At RANDOM, after ANY base game spin, ALL those money values may be collected and paid out. When this happens, your friendly fisherman will cast his net across the reels to drag in all the money.

At the same time, a random multiplier of up to 50x will be revealed from a treasure chest by the boat and may be applied to the total value of all those money symbols too. This could potentially lead to quite a windfall.

Remember, this is a random feature that can drop at any time.

How Free Spins Works In Amazon Xtreme

Pragmatic Play have really gone to town on the Free Spins round with lots of enhancements, modifiers, progressions and elements of jeopardy to add to the excitement in this game.

Unlocking the Round With Scatters, Re-Spins and Crocodiles

To start, you need to land 3 or more scatters which gets you 10 free spins.

Remember, if you have the Ante Bet on then you increase your chances of triggering the round. You might land 3 or more scatters in one go, but there is also a chance that if you land 2 then you will be granted a re-spin where reels with the scatters already on them drop one place each before holding for the re-spin. This gives you the chance to increase from 2 to 3, 4 or 5 scatters to set up free spins. Alternatively, a crocodile can appear at random to turn one standard symbol into a scatter.

Landing 2 Scatters – 3 are required to unlock free spins

Pick Modifiers Before the Free Spins Round Starts

Before the free spins round starts you must pick modifiers from the screen. You keep picking until you reveal a boot at which point your free spins start. If you landed 4 or 5 scatters, some modifiers will already have been chosen for you to give you a head start.

The potential modifiers are:

  • Additional free spins – up to 6 spins can be awarded this way.
  • Guaranteed fish – get up to 3 GUARANTEED fish symbols landing on the reels on EVERY spin in the free spins round.
  • Fishermen Wilds – Get a head start in collecting these symbols which unlock extras in the free spins round. You can start with up to 3 fishermen wilds on every spin.
  • Removing the lowest value fish symbols – you can remove the 2x and 5x symbols in the pick me feature, so that more high value fish symbols appear on the reels.

Fishermen Wilds Collect Fish Values and Re-Trigger the Round

Watch out for those Fishermen Wilds because they are key to your success in the bonus round. When they land they collect the values of all the fish on the reels.

Fishermen Wilds are also collected and every 4th to be collected gets you 10 more spins AND upgrades the multiplier applied to fish collections from 2x to 3x to 10x to 20x to 30x to 40x and finally to 50x if you manage to upgrade 8 times!

There are also several mechanisms built in that give you an extra chance of success on spins without wilds or money symbols. These work as follows:

If you land Fishermen Wilds but NO fish symbols then fish symbols may be added at random .. or a waterfall appears and changes all symbols on the reel except for the fishermen wilds.

And vice versa – if the reels stop and you have fish symbols but NO Wilds, then wilds will be pulled up onto the reels with a fish hook.

And finally, if you land a spin with NO wilds OR fish, then a fish hook may appear and drag reels up until both types of symbols are visible.


The Final Verdict

Despite giving us a rough ride in testing Amazon Xtreme feels like the best in the Big Bass series to date. The visuals and atmosphere are superb thanks to the fine artwork and fun soundtrack that makes the experience of playing a friendly, cheerful one.

And that’s before we even get onto the numbers and gameplay.

Perhaps what impresses most when playing this slot is the evolution of ideas from the first Big Bass slot to this one, some 2 ½ years later. Pragmatic Play have done what every good game developer does in a series. They’ve kept everything that made the original so popular whilst adding on enough new elements to make playing the latest iteration worthwhile. So, the fish symbol collects may be a familiar feature, but the free spins round modifiers are all new and add guaranteed jeopardy and thrills to playing the game. It’s possible to see how wins close to that 10,000x mark could be achieved by collecting lots of Fishermen Wilds.  And in typical high variance style, the progressive elements of the bonus round where multipliers grow and more spins are added, mean some truly thrilling moments are possible in this game.

We highly recommend this game to anyone who has enjoyed the Big Bass series to date, and even those new to it looking for their first taste of what it has to offer. It’s a compelling and ultimately hugely entertaining slot.

Useful Tips When Playing Big Bass Amazon Xtreme

Remember, online slots are games of chance, there is NO strategy that can improve your odds of winning. However, reading our review and following these tips will help you get the most out of your time playing this slot game.

1. Look Out For Extra Scatters

Pragmatic Play are giving you extra chances to unlock that free spins round here by granting re-spins if you land 2 scatters and through the random crocodile who appears and transforms one symbol into a scatter. So, it’s not the end if only 2 land on a spin.

2. Try For The Fishermen Wilds Modifiers

Look out for Fishermen Wilds – they are HUGE in the bonus round and if you can collect them before the round starts, even better. Remember, they collect all visible fish money symbols and add more spins when 10 or more are collected.

3. Choose Your Stake Carefully 

We also suggest for high variance games like this one that you choose your stake with care to absorb the rocky runs with little return. The minimum stake here is 10p which is ideal for wagering with a lower budget.

4. Choose From Our Recommended Slot Sites

We always recommend that you play at online slot sites from our lists because they are fully licensed in the UK which means that they are safe, fair and secure as they are subject to stringent UK regulations.
