Big Bass Bonanza is the first video slot game in a long list of exciting games offered by Big Bass slots, developed by Reel Kingdom for Pragmatic Play. Big Bass Bonanza is a simple slot game that takes players on a calm, immersive underwater adventure for casual players and big-time punters. Like Big Bass Bonanza Splash and Big Bass Bonanza Megaways, Pragmatic Play offers a Big Bass Bonanza demo game that can be played without making a deposit.
Played on a 5×3 grid, Big Bass Bonanza features 10 paylines and uses a fixed payline system where you will need to match at least three symbols. The base game of Big Bass Bonanza does not offer much beyond simple symbol matching, but it is simple enough to play. However, if you get three of the fish scatter icons anywhere in a single spin, the fisherman appears, and the real fun can commence.
Big Bass Bonanza offers two bonus features: money symbols and free spins. The former has a random number value, which can reward you with up to 2000x your stake after each spin. Furthermore, the fish paying symbols are also money symbols and can take a random money value, which can be won during the free spins feature.
To trigger the free spins feature, you will need to land at least three fish scatter icons anywhere on the grid in a single spin, as discussed earlier. For 3 scatter fish icons, you get 10 free spins, for 4 scatter fish icons, you receive 15 free spins, and for 5 scatter fish icons, you trigger 20 free spins.
The wild symbol will only appear in the free spins round, and all wild symbols obtained in the free spins round will remain until the end of the round. As an extra bonus, you can trigger an additional 10 free spins on every fourth wild symbol you obtain. The more you trigger the free spins, the higher the multiplier for the money symbol collection increases: 2x for the first retrigger, 3x for the second retrigger, and a massive 10x for the third retrigger. The multiplier applies to the retrigger spins, and retrigger spins are played only after the previous batch of free spins ends.
Please note that the maximum amount you can win in the free spins game is 2100x, and the current bonus round will stop once the maximum win has been reached.
A highly volatile game, the game has an impressive RTP of 96.71% which is slightly higher than the market average of 96%. High volatility means that Big Bass Bonanza pays out less often on average, so players should be mindful of their bets. However, the high volatility also means that the chance of getting big wins in a short period of time is higher. If you are an enjoyer of high max wins, you may be left unimpressed to hear that Big Bass Bonanza offers a relatively low max win of 2100x your stake compared to other online slot games.
Depending on which South African online betting site you use, the bet sizes will range from a low of R0.20 to a maximum of R14 000.00 per spin at Betway slots, SunBet slots and Hollywoodbets slots.
