Deploy into deep waters for high-volatility free spins with progressive multipliers up to 10x. Pragmatic Play's tactical fishing operation with 3,334x maximum win potential.
Land 3+ Scatter symbols to deploy into Free Spins. Collect Wild fisherman symbols - every 4th Wild retriggers with +10 spins and increases the collection multiplier: 1x → 2x → 3x → 10x. Choose pre-mission modifiers like More Fish, More Wilds, or start directly at Level 2.
All fish symbols carry random Money values from 2x to 5000x your total bet. During Free Spins, Wild fisherman symbols collect all Money fish on screen. Dynamite, hook, and bazooka features ensure fish and fishermen meet for maximum collection potential.
Alternative feature with robo-crab collectors under each reel. Start with 4 respins that reset when new Fish Coin symbols land. Fill entire reels to cash out on the crab. Random bomb drops double all coin values on a reel. Coin values: 1x to 25x bet.
Skip the wait and buy instant access to features for 100x your total bet. Choose between Free Spins mission or Stack the Cash operation. Available when Ante Bet is off. High volatility means explosive win potential when features hit.
Switch to 15x bet multiplier for significantly higher Scatter frequency on the reels. Increases your chance to trigger Free Spins naturally. When active, Buy Feature is disabled but Scatter appearances are boosted for organic feature hits.
5-reel, 3-row grid with 10 fixed paylines paying left to right. Top symbol is the Fisherman paying 50,000 CAD at max bet for 5-of-a-kind - the only symbol that pays from 2 matches. High-value tactical equipment and dragonfly round out the premium symbols.
This isn't your typical fishing slot - Reel Kingdom and Pragmatic Play fused the popular Big Bass series with a military tactical aesthetic. The underwater environment features deep ocean blues, amber-lit ruins, and a bearded fisherman kitted out in black tactical wetsuit armor with yellow goggles and a high-tech fishing weapon.
The progressive Free Spins mechanic is where the real depth lies. Unlike standard free spins that play at a fixed multiplier, Big Bass Mission Fishin' uses a Wild collection system across four levels. You start at 1x, but every 4 Wild fisherman symbols collected upgrades you: Level 2 doubles collections to 2x, Level 3 triples to 3x, and Level 4 jumps to 10x multiplier on all Money fish values. Each retrigger adds 10 more spins.
The Money fish mechanic adds volatility. Fish symbols don't just pay standard line wins - they also carry random multiplier values from 2x up to a massive 5000x your total bet. These values only pay when collected by Wild symbols during Free Spins, creating anticipation on every spin. Random features help: dynamite drops fish onto the reels when you have Wilds but no fish, hooks pull reels up to reveal Wilds when fish are present, and bazookas reshuffle symbols to create collection opportunities.
When you trigger the feature (either naturally with 3+ Scatters or via Buy Feature), you choose between Free Spins or Stack the Cash. Stack the Cash transforms the game completely - standard symbols vanish, leaving only Fish Coin symbols and blanks. Five robo-crabs position themselves under the reels as collectors.
You start with 4 respins. Every time a Fish Coin lands, it sticks and respins reset to 4. Fill an entire reel with coins and the crab below collects the total, then that reel clears to make room for more. The multiplier comes from random bomb drops: whenever at least one new coin lands, a bomb falls on a random reel and doubles every coin value there plus the crab's collected amount. This creates exponential growth potential if you can chain reel fills with bomb doublers.
Coin values range from 1x to 25x your bet - smaller than Money fish in Free Spins, but the doubling bombs and reel-fill mechanics compensate. The feature ends when respins hit zero without new coins landing.
Standard play uses a 10x bet multiplier with normal Scatter frequency. Activate Ante Bet to switch to 15x multiplier - this increases your total bet by 50% but significantly boosts how often Scatter symbols appear on the reels. For players who prefer organic feature triggers over buying, Ante Bet is the tactical choice. Note that Buy Feature is disabled when Ante Bet is active.
The Buy Feature costs 100x your current total bet and instantly triggers the feature selection screen. At minimum bet ($0.10 CAD), that's $10 to buy in. At maximum bet ($375 CAD), you're paying $37,500 CAD to trigger. This is designed for players with bankroll who want to skip base game variance and jump directly into the high-volatility features.
Because you choose between Free Spins and Stack the Cash after triggering, you can adjust strategy based on your preference: Free Spins offers higher maximum multipliers with the 10x Level 4 and 5000x Money fish potential, while Stack the Cash provides more frequent small-to-medium hits with doubling bombs. High volatility means long dry spells between features, but when they hit with the right combination of levels and Money fish, wins can approach the 3,334x cap quickly.
The Fisherman in his tactical gear is the premium symbol and doubles as the Wild during Free Spins. At max bet ($375 CAD), he pays $50,000 for 5-of-a-kind, $5,000 for 4, $1,250 for 3, and uniquely $125 for just 2 symbols - no other symbol pays from two matches.
High-value symbols include the iridescent Dragonfly ($25,000 / $3,750 / $750), the bronze Speargun with scope ($12,500 / $2,500 / $500), the Tackle Box with glowing treasure ($12,500 / $2,500 / $500), and the military Speedboat cutting through waves ($5,000 / $1,250 / $250).
Card symbols A and K both pay $2,500 / $625 / $50, while Q, J, and 10 each pay $1,250 / $250 / $50. These are rendered as translucent bubble-like 3D letters: purple A, blue K, pink Q, lime green J, and golden 10. The Scatter is a green bass fish with red fins in a rustic frame with "SCATTER" banner below.
Remember these base pays are just half the equation - during Free Spins, the fish symbols (Speedboat and any fish that appear) transform into Money symbols carrying random multiplier values that can dwarf standard line wins when collected by Wilds at higher multiplier levels.
Big Bass Mission Fishin' runs at 96.50% RTP across all modes: base game, Ante Bet, and Buy Feature all maintain the same return to player percentage. This is above the industry average of 96% and matches the standard Pragmatic Play offers on most of their premium releases.
Volatility is rated 5 out of 5 lightning bolts - maximum volatility. In practical terms, expect long stretches of small wins or dead spins in the base game, punctuated by explosive feature rounds that can deliver hundreds or thousands of times your bet when the progressive multipliers, Money fish, and retriggers align. Variance is high, so bankroll management is critical especially if playing at higher bet levels.
The maximum win is capped at 3,334x total bet. If during any Free Spins round your total accumulated win reaches this cap, the round immediately ends, you're paid up to 3,334x, and all remaining spins and features are forfeited. At max bet ($375 CAD), that's a cap of $1,250,250 CAD. At more modest $1 bets, the cap is $3,334. This ceiling prevents runaway wins but is still substantial for a high-volatility slot.
