RTP and other settings can differ between operators — always check the game's info screen where you play.

Big Bass Amazon Xtreme is a Pragmatic Play slot, made with studio partner Reel Kingdom, on 5 reels and 3 rows with 10 paylines. The provider's game page gives a default RTP of 96.07%, the maximum win is 10,000x the stake, and UK operators class the volatility as high. It was released in June 2023.

The return is the figure to check first. 7bet lists the same 96.07% as the provider, while Lottomart lists 92.03% for the same title. Both are UK operators and both numbers are real, because different configurations exist. The rest of this page explains the rules, the pick feature that precedes the bonus, and the official demo where all of it can be watched without a stake.

Key figures in one table

Every entry below comes from the provider's page, a UK operator page or a specialist review. Where two readings exist, the table shows both and says whose they are, since the configuration you meet depends on the casino.

Reels, lines and symbols

Wins form on the 10 paylines from left to right, starting from the leftmost reel. A line needs at least three low-paying symbols or two of the highest-paying symbols. The low-paying set is the 10 to A card ranks; the high-paying set is the fishing angle, toucan bird, fishing rod and backpack, which pay 50x to 200x the bet for a full line.

Big Bass Amazon Xtreme Slot Review: RTP, the Vase Pick and the Free Demo - key figures

Two special symbols sit on top of that. The scatter is represented by a fish symbol and appears on all reels. The fisherman symbol takes on the role of the wild, standing in for all other symbols except the scatter, and it appears during the free spins feature. The reels come to a random stop on every spin, so the same stake can produce very different outcomes from one spin to the next.

Fish money symbols and the random collect

Fish symbols carry a random cash value from 0.2x to 1,000x the bet, and they land in both the main game and the free spins round. In the base game there is a random chance that all visible cash values are collected after a spin. When that happens, a random multiplier from 1x to 50x is added to the total collected from the fish.

This matters for reading a session honestly: most fish you see in the base game are not paid, because nothing is there to collect them. The values on screen are possibilities, and the collect decides whether they become a win.

Big Bass Amazon Xtreme free spins: what the vases change

Landing 3, 4 or 5 scatters awards 10 free spins. Before the round begins there is a pick feature: you select vases to unveil modifiers, and the picks continue until a boot symbol is revealed. The provider describes it as choosing between six different game-altering mechanics before the free spins begin.

  • Extra free spins: 1, 2 or 3 at a time, with a maximum of 6 additional free spins.
  • More fish: 1, 2 or 3 money symbols land on each free spin for the rest of the round.
  • Collected fishermen: the round starts with up to three already collected Fisherman Wilds.
  • Remove lowest fish: the first reveal eliminates the 2x money symbol, the second removes the 5x symbol.

Inside the round, each fisherman that appears collects all cash values from the money symbols and then moves along the Progression Trail above the reels. Every 4th fisherman collected retriggers the feature with +10 free spins and applies a multiplier to the reached level: x2, x3, x10, x20, x30, x40 and x50 for levels 2 to 8. The pick is a choice of vases, not a skill test - what each vase hides is decided at random.

When only two scatters land

Two scatters in the main game can still lead to a third. With a Respin, the reels without scatters spin again. With the Hook, a hook animation may pull up one of the reels and reveal an additional scatter. Neither can be requested; both are random events.

Big Bass Amazon Xtreme RTP: two readings, one game

The default RTP is 96.07%, stated on the provider's game page and at 7bet. Lottomart lists 92.03%. RTP is a long-run average over a very large number of spins and says nothing about a single session. The practical step is simple: open the information screen of the game at your casino and read the figure there before you stake anything.

High volatility means payouts arrive unevenly: long stretches with little or nothing, and a small number of rounds that carry most of the return. The 10,000x cap is a limit set by the rules, reached via the free spins round, and not a likely result. Lottomart's own FAQ uses the words medium volatility while its game details say high; we follow the game details and 7bet.

Ante Bet and bonus buy

With the Ante Bet switched on, your current bet increases by 50% and more scatter symbols are added to the reels. The general release also has a bonus buy that opens free spins for 100x the bet; activating the Ante Bet disables it. At 7bet, a UK operator, Buy Bonus is listed as not available, so there the free spins come only from scatters.

Where it sits among the Big Bass games

Lottomart files the game under the Big Bass Bonanza series, and the specialist review names Big Bass Hold & Spinner, Big Bass Keeping it Reel and Big Bass Splash as earlier entries. The titles look alike in a casino lobby, and their figures are not interchangeable: every number on this page describes Big Bass Amazon Xtreme only. If a page quotes something else, check which game it names.

What we like

  • The provider publishes the default RTP on its own game page
  • The pick feature shows plainly which modifiers a round starts with
  • Retrigger multipliers follow a fixed published ladder, from x2 to x50
  • Official demo available, and the game is fully compatible with mobile devices

What to keep in mind

  • RTP differs by operator: 96.07% at one UK casino, 92.03% at another
  • High volatility, with long quiet stretches
  • No progressive jackpot feature
  • Bonus buy is not available at the UK operator we checked, though reviews of the general release describe it

Is it the right game for you?

It suits players who want to see how a bonus is put together: the vases, the trail and the multiplier ladder are all visible on screen. It is a poor match for anyone who prefers steady small returns, and for anyone inclined to stake more after a losing run - previous spins have no influence on the next one. Treat the cost as entertainment spend, decide the limit before you start, and use the demo first.

Our verdict

We rate Big Bass Amazon Xtreme well on our methodology. The default return is published by the provider, an official demo exists, and the rules of the bonus are laid out step by step rather than hidden. Marks come off for the spread of RTP between UK operators and for a volatility label that one operator states two ways on the same page. As a product it is clearly documented; none of its figures tells you how a session will go.
