Big Bass Boom is a slot developed by Reel Kingdom in partnership with the popular provider Pragmatic Play. Released on 01.10.2024, it features a fishing and underwater theme. The video slot has a simple interface and classic reel layout, along with several bonus features designed to boost winnings.
Key Facts About Big Bass Boom
The RTP of the slot is 97.97%, and with the bonus buy feature enabled, it increases to 98%. The developer lists the volatility as high, meaning winning combinations appear more often with medium or low payouts.
The slot uses a standard 5x3 layout with 10 paylines. Wins are formed by landing chains of 3 to 5 identical symbols. Only the highest-paying combination on each line is paid, while wins on different lines are added together. The bet range per spin is from $0.10 to $250.
The maximum possible win is 5000x the total bet. If this limit is reached during the free spins round, the bonus game ends automatically.
The interface includes “Quick spin” and “Turbo spin” modes, which speed up animations. In autoplay mode, players can set between 10 and 1000 spins to run without manual input.
There’s also a “Battery Saver” option in the settings to reduce power consumption when playing on smartphones or tablets.
Big Bass Boom by Reel Kingdom and Pragmatic Play is available at many reputable, licensed online casinos. A demo version allows free play with virtual credits that can’t be exchanged for real money. This test mode is designed to let users explore the game mechanics without financial risk.

Special symbols include:
- Wild – Substitutes for all symbols except the scatter. Helps complete winning lines and performs the same role during the free spins round.
- Scatter – Triggers the bonus round with free spins. Landing 3 to 5 scatters activates the feature with a chance to retrigger it.
- Money Symbol – Appears during the free spins round. Fish symbols that land alongside Wilds are assigned a value, which is summed and may be multiplied if enough Wilds with fishermen are on the screen.
Bonus Features
The core bonus is the free spins round, activated by landing 3 to 5 scatter symbols (10, 15, or 20 spins respectively). Additionally, if 3 Wilds appear during the bonus round, 10 extra free spins are awarded. This can happen up to 3 times, so the maximum number of spins during the feature is 50.
Multiplier Fish is another feature that works with Wilds during the bonus game. Each fish landing on the reels is assigned a random multiplier from 2x to 5000x and a cash value. The payout is awarded only if a Wild with a fisherman lands alongside the fish.
The bonus buy option allows players to purchase 10 free spins for 100x the current stake.
