Big Bass Bonanza — Full Review 2026
The fisherman collects money fish · Retriggerable Free Spins · One of Pragmatic Play's best RTPs
Big Bass Bonanza at a Glance
Our Big Bass Bonanza Review
Released in late 2020 by Pragmatic Play together with the Reel Kingdom studio, Big Bass Bonanza spawned one of the most-played slot series on the market. Its idea fits in one sentence: during Free Spins, a fisherman “catches” the value of every money fish on screen. No giant grid or cascades — just a 5×3 grid with 10 paylines that is easy to read from the very first spin.
Its first strength is its 96.71% RTP, one of the highest in the Pragmatic Play catalogue, above the 96.48% of Sweet Bonanza and the 96.50% of Gates of Olympus. Be careful, though: as with most Pragmatic Play slots, reduced-RTP versions exist. Check the RTP in the game info before betting. To understand what this figure really means, read our RTP guide.
Everything happens in the Free Spins. Triggered by 3, 4 or 5 Scatters (10, 15 or 20 spins), they bring in the fisherman, who collects the money fish. Every fisherman counts: every 4 fishermen, the feature retriggers with 10 extra spins and a multiplier that climbs to x2, then x3, then x10. This is the system that makes the x2,100 max win reachable.
The flip side is high volatility: the base game pays little and Free Spins can take a while to arrive. Big Bass Bonanza rewards patience more than short sessions.
For players who want a strong RTP and an easy-to-follow mechanic with real potential in Free Spins. If you prefer spectacular multipliers and cascading grids, try Gates of Olympus or Sweet Bonanza instead.
Game Mechanics
A classic layout: 5 reels, 3 rows and 10 fixed paylines. Wins form from left to right with at least 3 matching symbols on a line.
Fish symbols carry a cash value. In the base game they do not pay on their own: they come into their own in Free Spins, when a fisherman lands at the same time.
3, 4 or 5 Scatters trigger 10, 15 or 20 Free Spins. The fisherman (Wild) only appears during this bonus, where he collects the value of every visible fish.
Every 4 fishermen collected award 10 extra Free Spins and a multiplier on the fishermen's wins: x2, then x3, then x10 on the third retrigger.
The Big Bass Series
The original's success led to a whole family of Pragmatic Play sequels that keep the fisherman and money fish with twists: different grids, extra features, higher max wins. The original remains a benchmark thanks to its 96.71% RTP, often higher than its sequels'.
