Page updated July 2026
Big Bass Bonanza Hold & Spinner blends two of Pragmatic Play's most reliable mechanics into one release, pairing the series' signature retriggerable Money symbol free spins with a newer Hold & Spinner respin feature layered on top.
This entry leans toward river or lakeside fishing rather than open-sea angling, with a frog, dragonflies and lush foliage framing the top of the grid, while fish swim gently through the water in the background. It carries the same cheerful, easygoing vibe that's defined the franchise from the start — bright colours, a bubbly soundtrack, and nothing that demands much concentration to enjoy.
Playable across desktop, tablet or mobile, stakes run from 10p up to £250 a spin. The default RTP sits at 96.07%, rising marginally to 96.09% with the Ante Bet switched on, which increases the stake by 50% in exchange for improved scatter odds. Free spins and Hold & Spinner buy options are also available, both running at the same 96.07% baseline — though as always, lower-RTP configurations may be in play depending on the operator, so the in-game paytable is worth checking.
Set across a 5-reel, 3-row grid with 10 fixed paylines, the game is rated 5 out of 5 for volatility — as aggressive as this series gets. Line wins take something of a back seat to the main event: collecting Fish Money symbols, whose values can add up to serious sums once the Hold & Spin mechanic gets going. A five-of-a-kind line of Fish Money symbols alone pays out a hefty return before any collection bonus even factors in.
The maximum win reaches 10,000x the stake, putting it toward the upper end of the standard Big Bass entries and rewarding the patience that its high volatility demands.
Big Bass Bonanza Hold & Spinner works because it doesn't try to reinvent either mechanic it borrows from — it simply combines two proven systems that Pragmatic Play knows inside out. For players who enjoy the collection-and-respin loop of hold-and-spin slots but also want the series' classic free spins retrigger structure layered in, this is a strong pick. As with any high-volatility title, running a session through the free demo at johnessyslots first is the sensible way to gauge the pacing before betting real money on landing that 10,000x ceiling.
