How Big Bass Amazon Xtreme Works
Game Setup and Base Mechanics
Big Bass Amazon Xtreme is a 5-reel, 4-row video slot with 10 fixed paylines paying left to right from the leftmost reel. The game is set in the heart of the Amazon rainforest, with an underwater scene below the surface where you'll spin the reels, and a fisherman character sitting in his canoe above, fishing line cast into the depths.
You'll encounter high-value symbols like the Toucan (top payer at 400x for five of a kind), Piranha (200x), Fishing Rod (100x), and Backpack (100x). Lower-paying card symbols A, K, Q, J, and 10 round out the paytable with bubbly, underwater-styled letters.
Money Symbols and Base Game Collection
Money symbols appear on all reels displaying random values: 0.2x, 0.5x, 1x, 2x, 3x, 4x, 5x, 10x, 15x, 20x, 25x, 50x, 200x, 250x, 333x, 500x, or a massive 1000x your total bet. In the base game, there's a random chance after any spin that all Money symbol values on screen are collected and awarded to you, with a random multiplier between 1x and 50x applied to the total.
Free Spins Trigger and Pick Bonus
Land 3 or more Scatter symbols (the colourful fish cluster badge) to trigger the free spins feature and receive a base 10 free spins. But before the spins start, you enter a temple room filled with ancient pots — this is the Pick Bonus.
Click on pots to reveal modifiers until you uncover a boot, which ends the picking phase. Available modifiers include:
- +1, +2, or +3 Free Spins: Add extra spins to your round (max 6 additional via this modifier)
- Guaranteed Fish +1: Reveal up to three of these to guarantee 1, 2, or 3 Money symbols appear on every free spin for the entire round
- Already Collected Fishermen Wilds: Start the round with 1, 2, or 3 Fisherman Wild symbols already counted towards your first retrigger
- Remove Lowest Fish: First reveal removes the 2x Money symbol value from the pool; second reveal removes 5x
If you triggered with 4 Scatters, one boot is pre-revealed (more picks). With 5 Scatters, two boots are pre-revealed (even more picks).
Free Spins Round and Fisherman Wild Collection
During free spins, Fisherman Wild symbols appear on all reels. These substitute for all symbols except Scatter and Money symbols — but more importantly, they collect the values from all Money symbols on screen. Each collected value is then multiplied by the current level multiplier (starting at 1x).
Every Fisherman Wild that lands is collected. When you collect your 4th Fisherman Wild, the feature retriggers: you're awarded 10 more free spins, and the multiplier increases. The progression goes 1x → 2x → 3x → 10x → 20x → 30x → 40x → 50x across eight levels. After the eighth level, you can't retrigger anymore.
Random Events During Free Spins
The Amazon has a mind of its own. Random events can trigger at the end of any free spin to keep the action going:
- Fisherman Wilds on screen but no Money symbols? Money symbols can appear in random positions
- Money symbols on screen but no Fisherman Wilds? A hook pulls a random reel up to drag Wilds onto screen
- A waterfall animation can cascade down and change all non-Wild symbols to new ones
- A hook can appear and pull reels to bring both Fisherman Wilds and Money symbols into view
Maximum Win Cap
If your total win during a free spins round reaches 10,000x your bet, the round immediately ends, you're paid the capped amount, and all remaining spins are forfeited. With the 50x multiplier and 1000x Money symbols in play, this cap can be hit faster than you'd think.
RTP, Volatility, and Bet Range
Big Bass Amazon Xtreme has an RTP of 96.07% in base game and when buying free spins. When using Ante Bet mode (the "Higher Chance to Win Feature" toggle), RTP is 96.06%. Volatility is rated 6 out of 6 flames — high volatility means wins are less frequent but can be significantly larger when they hit.
You can bet from $0.10 (1 coin per line at $0.01 coin value) up to $375.00 (10 coins per line at $2.50 coin value with Ante Bet at 15x multiplier). In Ante Bet mode, your bet increases by 50%, but Scatter symbols appear more frequently on the reels, making free spins triggers more common. Note that Buy Free Spins is disabled when Ante Bet is active.
To buy free spins directly, it costs 100x your current total bet. When bought, the triggering spin will land 3, 4, or 5 Scatters randomly, affecting how the Pick Bonus plays out.
