Big Bass Amazon Xtreme Slot Review: 5x3 Fishing Slot with Pre-Bonus Pick, 50x Multipliers and 10,000x Max Win

What makes the Big Bass Amazon Xtreme slot different

Big Bass Amazon Xtreme is the June 2023 chapter of the Big Bass series from Pragmatic Play and Reel Kingdom, and it raises the stakes. The win cap sits far above the 2,100x of the original Big Bass Bonanza, and a pick-and-click round now runs before the bonus begins.

That Pre-Bonus Pick Round is the hook. Land three or more Fish Scatters and, before a single bonus spin is played, you open pots that reveal modifiers for the round ahead: extra spins, more fish, more Fishermen or the removal of the lowest fish value.

Around it sit ten fixed paylines, Money Fish, a Fisherman Wild that collects them, a multiplier trail with retriggers, an Ante Bet and a Bonus Buy. In my view it is the most feature-packed Big Bass slot so far and also one of the least forgiving.

The 96.07% RTP sits at the industry average and the volatility is rated 5 out of 5, so the game suits players who can sit through dry spells. Its 10,000x cap is the highest in the series, above Big Bass Splash at 5,000x and Bigger Bass Blizzard at 4,000x.

How to play Big Bass Amazon Xtreme

The game runs on five reels and three rows. A win needs three to five identical symbols on one line, on adjacent reels, starting from the first reel on the left. Only the top symbol, the fishing float, pays for two of a kind.

There are no cascades. Symbols stay where they land and every spin gets one chance to form a combination. The base game feels tight by design: most of what this slot can pay is locked inside the bonus round.

Fish Scatters are the way in. Three, four or five of them on one spin open the pick round and then the bonus.

How the 10 fixed paylines work

Ten fixed paylines means ten predetermined lines across the 5x3 grid. You do not need eight matching symbols anywhere on screen, as in a pay-anywhere slot, and you do not need clusters. You need matching symbols on one specific line, read from left to right.

• The lines cover the three horizontal rows plus several V-shapes and zigzags.
• All ten lines are active on every spin, and none of them can be switched off.

Early tracking data puts the hit frequency at around 11.76%, roughly one winning spin in every eight or nine. Treat the figure as an estimate from play data, not as a provider statement.

Because the lines are fixed, your bet is always spread across all ten of them. A slot with adjustable lines lets you narrow the coverage, and a pay-anywhere game such as Sweet Bonanza ignores position altogether; here a symbol only counts on an active line that starts on the first reel. The hit rate is lower than on medium-volatility slots, which is the price of the high variance.

Money Fish symbols and the Fisherman Wild collect feature

Money Fish are cash-on-reel symbols. Each one lands with a value printed on it, and that value has nothing to do with the paylines.

The Fisherman Wild turns those values into a payout. According to the in-game paytable he appears on all reels during the bonus round, substitutes for every symbol except the scatter and the money symbol, and collects every Money Fish in view when he lands.

• One Fisherman collects every fish on the screen, wherever it sits.
• Two Fishermen on the same spin each collect every fish. The values are not split between them.

The screenshot above shows the mechanic in one frame: two fish worth 700.00 each, a Fisherman on the x2 level, and 2,800.00 collected. Fish that land with no Fisherman in sight pay nothing.

Two worked examples

• One Fisherman, three fish: fish worth 10x, 20x and 50x are on screen when a Fisherman lands. He collects 80x the bet.
• Two Fishermen, five fish: fish worth 5x, 10x, 20x, 50x and 100x add up to 185x. Each Fisherman collects the full amount, so the spin pays 370x.

The values in these examples are illustrative. The point is the difference from regular symbols: a regular symbol pays through a line, while a Money Fish pays its printed value from any position, and only when a Fisherman is there to collect it.

Pre-Bonus Pick Round and its modifiers

The pick round starts the moment the scatters land. The screen fills with clay pots around a golden fish, and each pot you open reveals one modifier for the round that follows.

You cannot see inside a pot, so no pattern of picking improves the result. What the round does is make every bonus different, and it is my favourite part of the game: you know how the round is loaded before the first spin is played.

An example: pots that reveal +2 and +3 spins turn the starting ten into fifteen, and a Remove Lowest Fish token means the smallest value no longer takes up space on the reels. Unlike a bonus that simply starts spinning, this one is shaped by what you uncover first.

Multiplier trail levels and bonus round retriggers

The bonus round opens with ten spins plus whatever the pots added. Every Fisherman Wild that lands fills one slot on the trail above the reels, and each fourth Fisherman retriggers the round with ten more spins and lifts the multiplier to the next level.

Money Fish collected by a Fisherman are multiplied by the current level, so the same fish is worth ten times more on level 4 than on level 1. This is where the win cap becomes reachable: a late trail level, high-value fish and a Fisherman to collect them.

How a round can unfold

• Early progress: four Fishermen in the first spins add ten spins and move the trail to x2. Four more add another ten and move it to x3, so the round has already run past twenty spins.
• A long round: twelve Fishermen mean three retriggers, thirty extra spins and the x10 level. Every fish collected after that point is paid at ten times its value, over a round of forty spins or more.

Big Bass Amazon Xtreme bonus buy and ante bet

Both options sit to the left of the reels. The Bonus Buy costs 100x the bet and guarantees a scatter trigger on the next spin, pick round included. In our screenshot a 2.00 bet shows a buy price of 200.00.

The Ante Bet is the cheaper lever. Switching it on lifts a 2.00 bet to 3.00 in exchange for what the game calls a higher chance to win the feature, so you pay half as much again on every spin.

Should you buy the bonus? That depends on your bankroll, not on the game. At 100x a spin you pay a premium for instant access, and not every bought round returns its price. The Bonus Buy is also unavailable in some jurisdictions, the UK among them.

If your bankroll allows it and your jurisdiction permits it, the buy is the direct way into the feature where the trail and the retriggers do their work. Be ready for the variance: plenty of bought rounds end well below the price.

Big Bass Amazon Xtreme paytable and toucan symbol values

The paytable is short: four picture symbols and five card symbols. The payouts below are multiples of the total bet, worked out from the in-game paytable in the screenshot.

The float is the only symbol that pays for two of a kind, at half the bet. Three matching card symbols return a fifth of the stake, so most line wins give back less than the spin cost. The real spikes come from Money Fish collected on a high trail level.

On a flat stake of 1, five floats on a line pay 200, five toucans 100, five rods or backpacks 50 and five aces or kings 10. Four of a kind pays a fraction of that, and three of a kind less again, so do not expect small combinations to carry a session.

Where the real money is

1. Fisherman Wilds collecting Money Fish in the bonus round
2. The multiplier trail and its retriggers, which stretch the round and raise every collected value
3. The 10,000x win cap, the ceiling for any single round

Big Bass Amazon Xtreme features at a glance

Bottom line: the main route to a big result is the bonus round, where the trail climbs, retriggers extend the round and high-value Money Fish are collected at a multiplied value. The base game mostly keeps the balance moving between triggers.

Bankroll management and Big Bass Amazon Xtreme demo drills

Rule of thumb: keep 200 to 300 bets in reserve. At a 0.10 stake that is 20 to 30, at 1.00 it is 200 to 300, and at 5.00 it is 1,000 to 1,500.

The reason is simple. High volatility on ten lines means long gaps between meaningful wins. Early tracking data suggests the bonus lands about once in 148 spins on average, and 50 spins or more with nothing notable is normal, not a sign that a win is close.

Three demo drills before you stake

1. Spin 200 to 300 times in the demo and note how often the bonus round triggers.
2. Track what a typical line win looks like: one three-symbol hit, or several lines at once?
3. Play Big Bass Splash at the same stake and compare how the two bonus rounds feel.

Big Bass Amazon Xtreme on mobile

This is a standard Pragmatic Play and Reel Kingdom HTML5 build. The 5x3 grid works cleanly in portrait and in landscape, animations are smooth and the pick round is easy to use by touch.

In portrait the reels sit in the upper half of the screen and the controls move below them: the spin button, the bet size, the Ante Bet switch and the buy button all get their own space.

Touch controls respond well: tapping to spin, change the bet, open the paytable or buy the bonus where it is offered feels natural. The Amazon theme keeps its detail on a small screen, and the build is light enough to run without heavy lag on older devices.

Big Bass Amazon Xtreme RTP and volatility

The advertised return matches the industry average, since most modern slots sit between 96% and 96.5%. The catch is that Pragmatic Play ships this game in several configurations, and the operator chooses which one runs.

Open the game info before you play and read the figure there. RTP is also a long-term theoretical average: it says nothing about a single session, in which you can lose a balance in ten minutes or land a large win on the first trigger.

Big Bass Amazon Xtreme vs Bigger Bass Blizzard and Big Bass Splash

Amazon Xtreme has the highest cap of the three and puts a pick round in front of the bonus. Bigger Bass Blizzard stretches the grid to four rows and twelve lines, while Big Bass Splash keeps the classic layout.

Note: multiplier ceilings, feature availability and RTP configurations can differ with the casino's jurisdiction and the build it runs.

Big Bass Amazon Xtreme pros and cons

My verdict: a strong choice for players who enjoy the Big Bass formula and can afford its variance, and a poor one for a small balance.
