Only one fishing trip gets this wild!
During Free Spins, every Fisherman Wild symbol collects Money symbol values. Every 4th Wild collected retriggers the feature with escalating multipliers up to 50x.
Before Free Spins begin, pick ancient pots to reveal modifiers: extra spins, guaranteed fish, pre-collected Wilds, or removal of lowest Money values. Pick until you hit a boot.
Money symbols display random values from 0.2x up to 1,000x your total bet. In the base game, they can randomly trigger with multipliers up to 50x applied to all collected values.
Big Bass Amazon Xtreme plunges you deep into the heart of the Amazon jungle, where a bearded fisherman in his weathered canoe searches for the catch of a lifetime. This 5-reel, 4-row slot with 10 fixed paylines delivers high-volatility action across an underwater tableau teeming with exotic fish, ancient temples, and treasure beyond measure.
The game's visual design immerses you in a split-world perspective: above the waterline, dense tropical foliage bathes in golden sunlight whilst the fisherman casts his line; below, a teal-blue aquatic realm hosts the reels themselves, framed by fishing nets and swaying river plants. This isn't your typical fishing trip—it's an archaeological expedition meets extreme angling, and the stakes reach 10,000x your total bet.
Landing 3 or more Scatter symbols (the cluster of exotic fish) triggers the game's centrepiece: the Free Spins round. But before the spins begin, you're transported to a torch-lit temple chamber for the Pick Bonus. Here, ancient clay pots await your selection—each conceals a modifier that enhances your upcoming Free Spins:
The picking phase ends when you reveal a boot. If you triggered with 4 Scatters, one boot is already revealed (more picks for you). With 5 Scatters, two boots are pre-revealed, granting even more modifier selections.
Once Free Spins begin, the Fisherman Wild symbol appears on all reels. Each Wild doesn't just substitute—it actively collects the values from every Money symbol visible on screen. These collected values accumulate, and when your spins conclude, the total is paid out multiplied by your current level multiplier.
Here's where Big Bass Amazon Xtreme earns its name. Every Fisherman Wild that lands is collected towards a retrigger meter. Every 4th Wild collected awards 10 additional Free Spins and increases the Money collection multiplier:
After reaching the 50x multiplier at level 8, no further retriggers are possible—but by then, every Money symbol collected is worth 50 times its displayed value. This escalation system creates explosive win potential, especially when combined with guaranteed fish modifiers ensuring constant Money symbols on screen.
During Free Spins, the Amazon reveals its mysteries through random events that rescue dry spins:
These interventions ensure the feature maintains momentum, preventing frustrating spins where Wilds and Money symbols miss each other entirely.
Whilst the Free Spins feature delivers the main action, the base game offers its own Money symbol mechanic. After any base game spin, there's a random chance that all Money symbol values on screen are collected and awarded, with a random multiplier between 1x and 50x applied to the total. This provides sporadic big wins outside the bonus, keeping base game play engaging.
Additionally, when 2 Scatters land, random assist features can help you reach the third: Scatters may nudge down one position whilst other reels respin, or a crocodile may emerge to transform a symbol into a Scatter. These near-miss mechanics heighten tension and increase your chances of triggering the feature naturally.
For players seeking more frequent Free Spins triggers, the Ante Bet option increases your total bet from 10x to 15x (a 50% increase) in exchange for additional Scatter symbols on the reels. This significantly raises the probability of hitting 3+ Scatters naturally. However, activating Ante Bet disables the Buy Free Spins option—you must choose one approach or the other.
When Ante Bet is off, you can purchase immediate entry to the Free Spins round for 100x your current total bet. The triggering spin will land 3, 4, or 5 Scatters randomly, affecting how many boot items are pre-revealed in the Pick Bonus (and thus how many modifiers you can collect). This option suits players who prefer guaranteed feature access over base game grinding.
The paytable blends thematic Amazon wildlife with classic card values:
All symbols pay left to right on adjacent reels starting from the leftmost reel. Only the highest win per payline is paid, but multiple payline wins are summed together.
Big Bass Amazon Xtreme operates on a 5x4 grid with 10 fixed paylines. The RTP stands at 96.07% for both base game and Buy Free Spins mode, with Ante Bet mode marginally lower at 96.06%. Volatility is rated high (6 out of 6 flames on the game's volatility meter), meaning wins arrive less frequently but with greater potential magnitude.
Bet sizes range from £0.10 minimum to £375 maximum (with Ante Bet active; £250 maximum without Ante Bet). The maximum win is capped at 10,000x your total bet. If your Free Spins round reaches this cap, the feature immediately ends, the win is awarded up to the limit, and all remaining spins and features are forfeited. This cap applies across the entire Free Spins round, not per individual spin.
Developed by Reel Kingdom for Pragmatic Play, Big Bass Amazon Xtreme is built in HTML5, ensuring seamless performance across desktop, tablet, and mobile devices. The game offers multiple speed settings—normal, quick spin, and turbo—with keyboard controls (Space or Enter to spin) and an Autoplay function for those who prefer automated play.
Visual and audio toggles allow customisation: you can independently disable ambient music or sound effects, enable Battery Saver mode to reduce animation speed, or suppress the intro screen on subsequent sessions. The underwater environment, detailed character animations, and dynamic lighting effects remain smooth even on mobile, though turbo mode strips back some flourishes for faster reel cycles.
Big Bass Amazon Xtreme is available at UKGC-licensed online casinos. All play must comply with UK Gambling Commission regulations, including age verification (18+), deposit limits, and self-exclusion tools. If you feel your gambling is becoming problematic, support is available through GamCare, BeGambleAware, and the National Gambling Helpline.
The game includes a detailed rules section accessible via the 'i' button, covering all mechanics, paytables, and feature behaviour. A game history log tracks your recent rounds for transparency. Remember: the maximum win cap of 10,000x bet means even the longest Free Spins sessions cannot exceed this limit, and high volatility means extended losing streaks are possible before significant wins occur.
