Slot developers are the backbone of the modern iGaming industry, launching thousands of slot games each year that showcase their creativity and innovation. Reel Kingdom is one of the most notable slot developers out there, which has gained a notable reputation thanks to their Big Bass series. The developers have implemented the fishing theme into all releases in the series, with some titles also featuring elements from other themed slots, making them extra special. Regarding the bonus features, Reel Kingdom has ensured that all titles in the series implement interesting gameplay mechanics. One of the most notable features Reel Kingdom has implemented in this series is the Fisherman Wild, which has become one of the most recognisable icons in online slots.
One reason the Big Bass titles continue to garner attention is the clarity with which their bonus structures are communicated. Promotional terminology, such as Gold Cash Free Spins, is often used by operators when referencing feature-based gameplay.
A Background to the Developers
Only a few development studios have achieved the level of popularity that Reel Kingdom has, which entered the iGaming sector in 2025. Despite being mostly remembered for their Big Bass series, Reel Kingdom has released a range of alternate games, bringing the count to over 100 slots. The Welsh-based developers are the founders of one of the iGaming giants, Pragmatic Play, which has assisted in their slot creation process.
Big Bass Bonanza
The title that started it all for Reel Kingdom in the fishing series was Big Bass Bonanza, which launched on screens in 2020. Despite being the oldest release in the series, Big Bass Bonanza is one of Reel Kingdom’s most popular slots and has influenced all subsequent titles. The gameplay in the Big Bass Bonanza slot will take place across a 5×3 playgrid layout with 10 paylines, a layout used in many succeeding releases.
The design of the Big Bass Bonanza slot is sleek and well-crafted, featuring many elements that showcase the fishing theme without overdoing it. The reels are fully submerged underwater, with aquatic elements that enhance the environment, including coral reefs and vertical bubble streams that separate the reels.
Big Bass Bonanza was the first title in the series and showcased the iconic Fisherman Wild symbol, a fisherman holding a fish. Only in the Free Spins feature, the symbol can land on the reels to substitute for any base game symbol, as well as collect the values of any Fish symbols that land in the same spin. Each time the Fisherman Wild is landed, it will be added to a progression trail where additional free spins and multipliers can be triggered.
Big Bass Amazon Xtreme
Reel Kingdom has given the traditional Big Bass slots design a reskin in this release, with gameplay set in the depths of the Amazon rainforest. The title was released by Reel Kingdom in 2023 and retains many of its core features, with nuanced mechanics that set it apart. Despite featuring new mechanics and a fresh design, the gameplay takes place on a 5×3 playgrid with a total of 10 fixed paylines.
The playgrid will still take place fully submerged in an underwater environment, with the Amazon River expanding into the distance. Under the water’s surface, a range of aquatic plants adds to the aesthetic, and a sleeping fisherman casts his net from a wooden boat above the reels. Above the water, Reel Kingdom has added a range of trees that showcase the Amazon twist well.
Reel Kingdom has added some additional bonus features to the gameplay in the Big Bass Amazon Xtreme slot. The Free spins feature can introduce the Fisherman Wild symbol to the reels, with it serving the same purpose as the previous title mentioned. Where this title differs is the ‘Pick a Pot’ feature, which can offer enhancements before the Free Spins feature begins.
Big Bass 3 Little Fish – Big Bass Jackpot Bonanza
One of the latest released titles in the series is the Big Bass 3 Little Fish – Big Bass Jackpot Bonanza slot game. The title launched in the early stages of 2026, with unique bonus features and the chance to trigger one of four jackpot titles. The fishing theme is maintained in this slot, though the visuals have taken a slight spin, with gameplay set in a swamp-like environment. Once again, Reel Kingdom has opted for a 5×3 playgrid with 10 paylines, on which matching symbol combinations can land.
Big Bass 3 Little Fish – Big Bass Jackpot Bonanza features a detailed visual display with a range of advanced graphics. Under the water, there is a range of aquatic plants of many colours, as well as rocks and stones. The swamp-like aesthetic features tall grass visible under the water and extending high above it.
The Big Bass 3 Little Fish – Big Bass Jackpot Bonanza slot features some interesting game mechanics, with the Fisherman Wild being utilised once again. During the Free Spins feature, players can land Scatter symbols that may trigger a random modifier.
