Pragmatic Play (Reel Kingdom) | 96.71% RTP certified | Responsible gambling supported
Big Bass Bonanza delivers a certified 96.71% RTP across all ten fixed paylines, placing it firmly in the competitive range for high-volatility fishing slots from Pragmatic Play's Reel Kingdom studio.
This 5-reel, 3-row underwater slot maxes out the volatility meter at 5 out of 5 lightning bolts. Expect less frequent hits in the base game but significantly larger payouts during the free spins feature when wild fisherman symbols collect money values and retrigger multipliers climb to 10x.
Bet range spans £0.10 to £250.00 per spin, with the maximum win capped at 2100 times your total stake—if you hit that threshold during a bonus round, the feature ends immediately and awards the capped amount.
Three or more scatter symbols (the leaping bass emblem with red "SCATTER" banner) anywhere on the 5x3 grid activate the free spins round. Here's how the graduated awards and wild collection system work:
Trigger: 3 scatter symbols
The fisherman wild appears on all five reels during free spins and collects every money symbol (fish on golden cards) visible on screen. Each money fish displays a random multiplier: 2x, 5x, 10x, 15x, 20x, 25x, 50x, or a massive 2000x your bet.
Trigger: 4 scatter symbols
Increased spins plus the same wild collection mechanic. Each wild fisherman that lands stays collected. When you accumulate four wilds total, the round retriggers with 10 additional spins and a 2x multiplier on all money collections.
Trigger: 5 scatter symbols
Maximum initial award. The retrigger ladder extends up to three levels: first retrigger applies 2x, second applies 3x, and the third escalates to 10x on all money symbol collections. After three retriggers, no further extensions are possible.
When only a single wild lands on a free spin, the game may randomly add extra money fish symbols to vacant positions at the end of that spin, significantly boosting collection potential before the next reel drop.
If your total win in any free spins round reaches 2100x your bet amount, the feature terminates immediately. You receive the 2100x payout, but all remaining spins and accumulated retriggers are forfeited. This cap applies to the cumulative win across all spins in a single bonus activation.
All symbols pay left to right on adjacent reels starting from the leftmost position across the ten fixed paylines. Only the highest win per line is paid; multiple line wins add together. Below are the 5-of-a-kind payouts (expressed as coin multipliers of your line bet):
Fisherman Wild: Appears on all reels during free spins only. Substitutes for everything except scatter. Collects all money symbol values on screen and is tracked cumulatively—every fourth wild collected awards +10 spins and increases the multiplier (2x, 3x, then 10x).
Scatter: The circular bass emblem with "SCATTER" text. Three, four, or five scatters trigger 10, 15, or 20 free spins respectively. Scatters pay from any position and do not need to be on a payline.
Winning in Big Bass Bonanza revolves around patience in the base game and explosive potential during the free spins collection mechanic. Here's the strategic breakdown:
Pro Tip: Autoplay with "Skip Screens" enabled speeds through the intro and end-of-feature animations, letting you cycle spins faster in pursuit of scatter triggers. Remember the 2100x cap—celebrate if you hit it early, as the round ends on the spot.
If your cumulative win during a single free spins round reaches 2100 times your triggering bet, the feature ends instantly. You receive the 2100x payout, but all remaining spins, retriggers, and any uncollected money symbols are voided. This cap is in place across all Pragmatic Play markets.
No. The fisherman wild symbol only lands during free spins on special reels. In the base game, you'll see the high-value fishing symbols (bobber, reel, dragonfly, tackle box), money fish, and low-value card ranks (A, K, Q, J, 10), plus the scatter.
You can retrigger the free spins feature up to three times by collecting every fourth wild fisherman. First retrigger (4 wilds): +10 spins, 2x multiplier. Second retrigger (8 wilds): +10 spins, 3x multiplier. Third retrigger (12 wilds): +10 spins, 10x multiplier. After the third retrigger, the feature cannot extend further.
Each money fish symbol displays a random multiplier chosen from: 2x, 5x, 10x, 15x, 20x, 25x, 50x, or 2000x your total bet. These values are collected by wild symbols during free spins. The 2000x multiplier is rare but can appear, especially on higher bet levels.
Yes. The game is built in HTML5 and runs seamlessly on iOS and Android devices in portrait or landscape mode. All controls—bet adjustment, spin, autoplay, settings, and information screens—are touch-optimised. The underwater theme and bubble animations render smoothly on modern mobile browsers.
