Big Bass Fishing Mission splits its win potential across two different bonus paths, letting Pragmatic Play players choose between the series' usual free-spins collection game or a separate pick called Stack the Cash once the trigger lands, with fish Money symbols worth up to 5,000x the stake sitting at the centre of both. Released in June 2024, the game keeps the underwater bubble-framed setting familiar from earlier entries but sets it at night, dressing a handful of symbols in loosely spy-themed touches to match the mission framing.
Reels run 5x3 with 10 fixed paylines, and stakes span 0.10 to 250 per spin. An Ante Bet raises the wager by 50% in exchange for extra scatters appearing on the reels, and the game runs at high volatility (5 out of 5) with a default RTP of 96.5%.
Landing five ten-to-ace card ranks in a row pays out the least, worth only 5x to 10x the stake. Above them sit the fish Money symbols alongside tackle boxes, boats, harpoon guns and dragonflies, together worth 20x to 200x. The fish carry an additional, separately assigned value between 2x and 5,000x the bet, only collectible once free spins begin. A wild fisherman symbol appears exclusively in that round and substitutes for everything except the Money and scatter symbols.
Three or more scatters open a choice between the two bonus rounds. Landing exactly two scatters in the base game can still trigger a hook or a respin that shifts existing scatters down the grid without letting them drop off, giving a chance at a third. Choosing free spins from 3, 4 or 5 scatters awards 10, 15 or 20 rounds respectively, and before they start, players click through hidden files to reveal modifiers — more fish or fisherman symbols on the strips, extra dynamite, hook and bazooka events, the progressive multiplier trail starting a level ahead, or two bonus spins added up front and on every retrigger. Inside the round, each wild collects every visible Money value and is itself tracked on a meter; every fourth wild banked adds ten more spins along with a multiplier of x2, x3 or x10 across three possible levels. Random events can also drop fish onto the reels, pull a fisherman in via hook, or transform surrounding symbols through a bazooka effect.
Choosing Stack the Cash instead clears ordinary symbols away, leaving only blank spaces and Fish Coin symbols worth 1x to 25x the bet, tracked by a robo-crab under each reel. Four respins reset every time a new coin lands, and once a reel fills entirely with coins they're banked to that reel's crab; each new coin also drops a bomb that doubles the values already held on a random reel. Payment comes once the respins run out.
Both routes can be bought directly for 100x the stake, with the RTP held at 96.5% either way.
Big Bass Fishing Mission has an RTP (return to player) of 96.50%. RTP is the theoretical percentage of total stakes a slot returns to players over a very large number of spins, as published by Pragmatic Play — individual sessions can land far above or below it.
Big Bass Fishing Mission is rated high volatility. High-volatility slots pay out less often, but wins tend to be bigger when they land — expect longer dry spells and larger swings to your balance.
The advertised maximum win for Big Bass Fishing Mission is 5,000x. Max wins are extremely rare by design — treat them as a ceiling, not an expectation.
Big Bass Fishing Mission is developed by Pragmatic Play and was released in 2024.
