Big Bass Amazon Xtreme keeps the 10-line fisherman collect and builds around it: a random base-game collect with up to 50x, vase picks that add spins, fish or fishermen before the round, and a trail of eight levels that lifts fish collections to 50x. Every step still needs four fishermen, the picks can end on the first boot, and the 96.07% RTP sits below Big Bass Bonanza's 96.71%.

Who it suits

Play this if…

  • You want a long ladder: eight levels, with fish collections multiplied up to 50x
  • You like shaping the round first: picks can add spins, fish and fishermen
  • You want fish cash outside the bonus: the random collect pays it at up to 50x

Skip this if…

  • You want a sure head start: a boot on the first pick starts the round with no modifiers
  • You want a higher RTP: 96.07% here against 96.71% in Big Bass Bonanza
  • You want frequent base wins: 84 of our 100 spins paid nothing, and three of a letter pay $0.20

Our test logged 100 spins of the Big Bass Amazon Xtreme slot demo at $1, plus one bought round.

What is the Big Bass Amazon Xtreme slot about?

The reels sit under a rainforest river, with the fisherman in a wooden boat at the top left, his net in the water. A REEL KINGDOM mark sits bottom left, below the ante switch and the BUY FREE SPINS price.

Wins pay left to right on 10 lines. At a $1 bet the fishing float pays $200 for five and $0.50 for two, the only two-symbol win. The toucan pays $100, the rod and the backpack $50 each. A and K pay $10 for five, Q, J and 10 pay $5, and three of any letter $0.20.

The fish are money symbols worth 0.2x to 1,000x the bet, in 17 steps. They have no line pay; their cash is won in free spins, or when a random base-game collect fires. The fisherman wild lands only in free spins and replaces every symbol except the scatter and the fish.

Big Bass Amazon Xtreme base game at a $1 bet: three toucans on the bottom row, fish worth $1.00, $1.00 and $0.20 above, WIN $3.00Spin 23 of 100 at $1: three toucans on the bottom row paid $3.00, and the $2.20 in fish above them stayed unpaid. FluxPlays demo test, 18 October 2026.

Big Bass Amazon Xtreme bonus features

A random fish collect in the base game

After any base spin, the game can add up the values of all fish on screen and pay them with a random multiplier of 1x, 2x, 3x, 4x, 5x, 10x, 20x, 30x, 40x or 50x. When it fires, the fisherman cheers over a glowing chest and a banner shows the sum.

Big Bass Amazon Xtreme base-game collect at a $1 bet: the fisherman cheering over a glowing chest, a $5.20 banner and five fish, WIN $5.20Spin 70 of 100 at $1: a random collect paid the five fish on screen, $5.20. FluxPlays demo test, 18 October 2026.

Scatters and help for the third one

The scatter is a leaping fish on every reel. Three or more give 10 free spins; four or five add no spins but open the pick game with one or two boots already revealed. When two land without a third, either both scatters drop a row while the other reels respin, or a crocodile turns one symbol into a scatter.

The vase pick before free spins

Each round, natural or bought, opens on 14 clay vases around a golden fish. Every pick reveals a modifier until a boot ends the picks, and a bar across the top lights the tiles won. The rules list four kinds:

  • More free spins: +1, +2 and +3 tiles, at most 6 extra spins in all
  • Guaranteed fish: up to three +1 tiles, for one to three fish on every free spin
  • Already collected fishermen: up to three fishermen counted toward the first retrigger before a spin is played
  • Remove lowest fish: found once, it takes the 2x fish value out of the round; found again, the 5x value goes too

Fisherman collects and an eight-level trail

In free spins each fisherman collects the value of every fish on screen, and the fishermen are counted until the round ends. Each fourth one adds 10 spins and raises the multiplier on fish collections: 2x at level 2, then 3x, 10x, 20x, 30x, 40x and 50x at level 8, the last of seven retriggers.

Help at the end of a free spin

With fishermen on screen but no fish, fish can drop into random positions, or a waterfall can change every symbol except the fishermen. With fish but no fisherman, a hook can pull a reel up to bring fishermen in, and a random hook can drag in both. The round runs on special reels.

Ante bet and Buy Free Spins

The HIGHER CHANCE TO WIN switch raises the bet multiplier from 10x to 15x, $1.50 at a $1 base bet. More scatters sit on the reels and natural free spins become likelier, the buy switches off, and the RTP is 96.06%. We kept it off: the game server's log shows ante level 0 on all 101 rounds.

BUY FREE SPINS costs 100x the base bet, $100 at $1, at the same 96.07% as normal play. There is one price and no choice of round; the scatters and the vase picks decide the rest.

Maximum win, RTP and bets

Wins stop at 10,000x the bet, $10,000 at $1, and a round that reaches the cap ends at once. The rules give a 96.07% RTP, bets of $0.10 to $375 against the $250 top bet most review sites list, and a LOW VOLATILITY badge where those sites say high.

What changed from Big Bass Bonanza

Both games' rules have 5x3 reels, 10 lines, a LOW VOLATILITY badge and a fisherman wild that lands only in free spins, where every fourth one retriggers the round. Big Bass Bonanza stops at three retriggers and 10x, pays its 2x to 2,000x fish only in free spins, gives 10 to 20 spins by scatter count and caps at 2,100x, with no buy or ante.

Amazon Xtreme runs the trail to 50x, pays fish in the base game too, gives four or five scatters revealed boots instead of 15 or 20 spins, and adds the buy and ante. The cap rises to 10,000x, while the RTP drops from 96.71% to 96.07% and Q, J and 10 pay $5 for five instead of $10.

We have also tested Big Bass Halloween Splash 1000: its pick is one pumpkin from six, its ladder stops at level 4 and 10x, and it caps at 20,000x under a medium badge.

Played on the official demo with play money, base spins started one at a time by a script clicking the spin button, without autoplay, in a single session; quick spin from spin 2 (speed only). The page was reloaded once before the first spin, and the balance was $100,000.00 again. The ante (HIGHER CHANCE TO WIN, $1.50 at $1) stayed off; the game server's log shows ante level 0 on every round. The game has no special modes and no gamble. The random base collect paid $5.20 on spin 70 and $4.40 on spin 71, both at 1x in the server's data. Spin 72's $15.00 was a single result: the other 99 spins returned $32.80. Free spins triggered once, on spin 74: three scatters, picks of FREE SPINS +1, FREE SPINS +2 and one guaranteed fish for 13 spins, two fishermen, no retrigger, $13.20; without spin 74 the base game returned $34.60. The Free Spins buy ($100) gave 11 spins after picks of one guaranteed fish and FREE SPINS +1, two fishermen and no retrigger, $22.40, a single result. Totals from the spin log: $200.00 staked, $70.20 returned, ending at $99,870.20. 100 spins and one buy cannot measure the RTP or the volatility.

The demo opened at $2.00 with the buy at $200; at our $1.00 the buy cost $100. A script clicked the spin button for each of the 100 base spins, without autoplay, and quick spin from spin 2 changed only the speed.

The first 12 spins paid nothing, and spins 55 to 69 were the longest dry run. Five spins carried the base game: spins 70 to 74 returned $37.80 of its $47.80, the other 95 spins $10.00.

Spins 70 and 71 both fired the random collect, for $5.20 and $4.40. In the game server's data each total equals the fish values in view, so both ran at 1x. Spin 72 then lined up four toucans on line 6 for $15.00, our best base win; without it, the other 99 spins returned $32.80.

Big Bass Amazon Xtreme spin 72 at a $1 bet, settled: five toucans on screen, four of them on line 6, a $0.20 fish, WIN $15.00Spin 72 of 100 at $1: four toucans on line 6 paid $15.00, our best base win. FluxPlays demo test, 18 October 2026.

On spin 74 the game server's data shows a respin inside the same paid spin, with three scatters, and the pick screen followed. Our picks found FREE SPINS +1, FREE SPINS +2 and one guaranteed fish before a boot: 13 spins with a fish on every one.

The fish came every time; the fishermen did not. Apart from $0.20, the money came from the round's only two fishermen, on free spins 11 and 12, who collected $4.00 and $9.00. It ended at $13.20 with no retrigger, and without spin 74 the base game returned $34.60.

The $100 buy announced "3 SCATTERS ENTRY!", and the picks gave one guaranteed fish and FREE SPINS +1, for 11 spins. Again two fishermen came, collecting $11.00 on free spin 7 and $9.00 on free spin 9; three other spins added $2.40. The round paid $22.40, 0.22 times its price.

Big Bass Amazon Xtreme result screen after our $100 buy at a $1 bet: YOU HAVE WON $22.40, two fishermen lit on the trail, WIN $22.40The $100 buy's result: $22.40 from 11 free spins, with two fishermen lit on the trail. FluxPlays demo test, 18 October 2026.

With two fishermen per round, the trail never reached a retrigger or a multiplier. We also never saw four or five scatters, FREE SPINS +3, already collected fishermen, REMOVE LOWEST FISH or a base collect above 1x; those come from the rules.

How the session split:

  • Base game, 100 spins at $1, spin 74's free spins included: $100.00 in, $47.80 back
  • Free Spins buy at 100x: $100.00 in, $22.40 back

In all we staked $200.00 and got $70.20 back, and the server balance ended at $99,870.20, as our log shows. Two rounds and 100 spins are far too few to judge a 96.07% RTP or the low badge.

Is Big Bass Amazon Xtreme worth trying?

Big Bass Bonanza, Big Bass Splash and Big Bass Halloween Splash 1000 all stop their fisherman ladder at 10x; this trail climbs to 50x. With picks that can stack spins, fish and fishermen before the first spin, and fish cash in the base game, a round here has more ways to grow than the original ever had.

Every step still needs four fishermen, though, and a boot on the first pick starts the round with no modifiers. Our two rounds showed a fish far more often than a fisherman to collect it. The 96.07% RTP sits below Big Bass Bonanza's 96.71%, and three of a letter return $0.20.

Frequently Asked Questions

Can I play the Big Bass Amazon Xtreme demo for free?+

Yes. This page runs the official Big Bass Amazon Xtreme demo from Pragmatic Play and Reel Kingdom with play money and no sign-up. Ours opened at a $2.00 bet with the buy at $200; five presses of the minus button took them to $1.00 and $100. The buy works in the demo, but not while the $1.50 HIGHER CHANCE TO WIN switch is on.

How does the pick game work in Big Bass Amazon Xtreme?+

Before every free spins round you pick vases until a boot appears. The rules list four kinds of modifier: up to 6 extra spins, up to three guaranteed fish per spin, up to three fishermen already collected, and the removal of the 2x and then the 5x fish value. Pragmatic Play's game page speaks of six mechanics; the bar on screen shows six tile designs, three of them for extra spins. Our picks gave 13 and 11 spins.

How is Big Bass Amazon Xtreme different from Big Bass Bonanza?+

Both run on 5x3 reels and 10 lines with a fisherman who collects fish in free spins, and both carry a LOW VOLATILITY badge. Amazon Xtreme adds the random base-game collect, the vase pick, a 100x buy and an ante, and stretches the retrigger ladder from 10x to 50x over eight levels. Its cap is 10,000x against 2,100x and its RTP 96.07% against 96.71%. We tested both games on 18 October 2026.

Do the fish pay in the Big Bass Amazon Xtreme base game?+

Only through a random collect. The fisherman wild lands only in free spins, and fish have no line pay of their own, so in the base game their cash is paid when the collect fires after a spin: every fish value on screen is added up and multiplied by 1x to 50x. In our 100 spins it fired on spins 70 and 71 in a row, for $5.20 and $4.40, both at 1x.

What are the RTP, volatility and max win of Big Bass Amazon Xtreme?+

The rules give 96.07% for normal play and for the buy, and 96.06% with the ante; review sites also list 95.08% and 94.05% versions that some casinos run. The rules page shows a LOW VOLATILITY badge. Wins are capped at 10,000x the bet, $10,000 at $1, and a free spins round that reaches the cap ends there. Our best result was the $22.40 bought round.
