Overview
The Big Bass Series is a collection of fishing-themed slots made by Reel Kingdom, a studio in Wales, UK, and distributed by Pragmatic Play. It started with Big Bass Bonanza, released in December 2020, and several new versions have come out each year since, making it one of the longest-running series in online slots. On AI Slot, game titles are written as “Big Bass.”
Every title shares the same basic framework: during free spins, the fisherman wild collects the cash values shown on fish symbols. This structure is called Money Collection, and only the setting, supporting features and max win change from title to title. Big Bass Hold and Spinner Megaways, released on August 28, 2023, was introduced as the 10th title in the series, and AI Slot’s free slots now include 37 games with Big Bass or Bigger Bass in the name.

RTP and max win are based on the AI Slot database. Depending on the casino, a lower RTP version may be in use.
Same Fishing, Different Numbers
Across the series, max win has grown steadily. The first title, Big Bass Bonanza, had 2,100x, which rose to 4,000x in Bigger Bass Bonanza, 5,000x in Big Bass Splash, and 10,000-20,000x in the Hold and Spinner line. Since 2025, titles using the 1000 series approach have followed, and Big Bass Splash 1000 goes up to 25,000x.
On the other hand, RTP mostly stays between 96.07% and 96.71%. As max win grows, big wins become rarer and more concentrated, so even within the same series, the 1000 versions can feel higher in volatility than the originals. If you’re new, it’s easier to learn the rules on Big Bass Bonanza, which has the simplest structure, and then move on to the expansions.
Common Supporting Features
- Fisherman level-ups: Collecting a set number of fishermen during free spins adds more free spins and raises the fisherman multiplier. This rule is shared by most titles.
- Hold & Spin: The Hold and Spinner line has a separate Hold & Spin round where money symbols lock in place and respins are played.
- Megaways: Two versions use Megaways, where the reel height changes with every spin.
- Seasonal looks: Seasonal editions often keep the rules the same and change the background, symbols and music to a Christmas or Halloween mood.
