Big Bass Bonanza is a 2020 slot by Reel Kingdom, developed under a Pragmatic Play license. It blends elements from two other games: Big Bass Splash and Sweet Bonanza. The influence of the latter is minimal, limited to certain mechanics.
The game’s key strength is its bonus round, which can be retriggered an unlimited number of times. Another strong point is an RTP above the industry average.
Technical Specifications
Big Bass Bonanza is a classic slot with 5 reels and 3 rows each. Winning combinations can form across 10 fixed paylines.
To win, 3 or more identical symbols must land on the screen. An exception is the float symbol, which pays with just 2 matches. If matching symbols appear outside a payline, the win is not counted.
The bet size ranges from 1 to 10 coins per line. Coin values range from €0.01 to €2.5. Therefore, the total stake per spin can range from €0.01 to €250.
The RTP of Big Bass Bonanza is 96.71%, which is above the industry average. The maximum theoretical win is x2,100 the total stake.
The provider rates the slot’s volatility at 4 out of 5, meaning high volatility. This ensures fewer long losing streaks and frequent shifts between small and large wins.
Gameplay in Big Bass Bonanza
To start a round, select the stake and click the button with two curved arrows. The reels will spin. If several identical symbols land on one of the paylines, a payout is triggered.
The game includes a quick spin mode. When activated, it shortens the spin animation. Normally, it lasts 2.5 seconds. With quick spin on, it drops to 0.7 seconds.There’s also a battery saver option in the settings. It simplifies graphics to reduce power consumption, especially useful for those playing on phones, tablets, or laptops.
The slot supports auto spins, launched via the “Autoplay” button. The number of spins can be set from 10 to 1,000. Spins will stop when this number is reached or the balance runs out. They can also be stopped manually.
Symbols in Big Bass Bonanza
Symbols in the slot are themed around fishing, along with standard playing cards from 10 to Ace.

The fisherman has no value of its own. It doesn't pay directly but works as a Wild and substitutes any missing symbol in a winning combo. The win is calculated based on the substituted symbol.
The fish on a hook also has no payout value. Its role is to trigger the Big Bass Bonanza bonus round.
Bonus Games
When 3 or more fish-on-hook symbols land on the screen, a free spins bonus round is triggered. The number of spins depends on the number of triggering symbols:
| Fish-on-hook symbols | Free spins |
|---|---|
| 3 | 10 |
| 4 | 15 |
| 5+ | 20 |
Fishermen that land during the bonus round are collected on a special meter and remain there until the round ends. If 4 are collected, 10 additional free spins are awarded. This process can repeat without limit.
The fish symbol during both base game and free spins can activate a special feature that applies a random multiplier from x2 to x50. This only happens when a winning combo appears along with the fish. The fish also has a fixed value and can create winning combinations on its own.
If fish symbols land on reels 1 and 3, reels 4 and 5 respin. This increases the chance of landing a third fish and triggering the free spins bonus round.
