Big Bass Mission Fishin features

Money Symbol
The fish paying symbols are also MONEY symbols. At every spin, the fish take a random money value which can be won during the FREE SPINS feature. Possible values are: 2x, 5x, 10x, 15x, 20x, 25x, 50x, 100x, 200x, 500x or 5000x total bet.
Free Spins
Hit 3 or more SCATTER symbols to trigger the FREE SPINS feature. In the base game whenever 2 SCATTER symbols hit without a third, there is a chance for another one to be brought onto the screen by a random feature: - Randomly, if the SCATTERS on the screen can move down one position without leaving the reel area, a respin is triggered where the reels with SCATTERS move one position down and the reels without SCATTERS respin. - Randomly, a hook can pull one of the reels up to reveal another SCATTER. Before the round starts, select one out of two possible features: FREE SPINS: Hit 3, 4 or 5 SCATTER symbols to trigger the FREE SPINS feature and win 10, 15 or 20 free spins respectively. Before the round starts, select files on the screen to reveal modifiers for the subsequent round, until you reveal a boot. Possible modifiers are: - MORE FISH - More fish symbols are present on the reel strips during the subsequent free spins round. - MORE FISHERMAN - More WILD symbols are present on the reel strips during the subsequent free spins round. - MORE DYNAMITES, HOOKS AND BAZOOKAS - During the round, the chance to hit dynamite, hook or bazooka spin feature is increased. - START FROM LEVEL 2 - The round starts from level 2 in the progressive feature. - +2 SPINS - The subsequent round starts with 2 more free spins from the beginning and 2 more spins are added to every retrigger. During the FREE SPINS feature each WILD symbol also collects all the values from MONEY symbols on the screen. All the WILD symbols that hit during the feature are collected until the end of the round. Every 4th WILD symbol collected retriggers the feature, awards 10 more free spins and the multiplier for MONEY symbol collection increases to 2x for the second level, 3x for the third level and 10x for the fourth level. The retriggered spins are played after the previous batch of free spins ends. The multiplier applies to the retriggered spins. After the fourth level, the feature cannot be retriggered anymore. Randomly, when there are fisherman symbols on the screen but no fish, at the end of a free spin, fish MONEY symbols can appear in random positions via the dynamite spin feature. Randomly, when there are fish symbols on the screen but no fisherman, at the end of a free spin, a hook will appear pulling a random reel up to bring fisherman symbols onto the screen. Also randomly, when there are fisherman symbols on the screen but no fish, at the end of a free spin, a bazooka animation can appear and change all the symbols from the screen, except for fisherman symbols to something else. Special reels are in play during the feature.
Stack the Cash
When selecting the STACK THE CASH feature, for the round, the normal symbols fade away and only COIN symbols and blanks are left on the reel strips. This is the FISH COIN symbol. It appears on all reels during the STACK THE CASH feature. At every spin, it takes a random value from a pre-defined set. Possible values are: 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x or 25x total bet. During this round, under each reel, a robo-crab appears. The round starts with 4 respins and every time a FISH COIN symbol hits, it remains on the screen and the amount of respins is reset back to 4. When a reel is filled with FISH COIN symbols, all their values are collected on the robo-crab under the reel and the reel is cleared of symbols. Whenever at least one new FISH COIN symbol hits, a bomb drops on a random reel which doubles the values of all the FISH COINS on it and the robo-crab below. At the end of the round, the values of all robo-crabs are added together and paid. The round ends when there are no more respins left.
Ante Bet
The player has the option to select the bet multiplier. Depending on the selected bet, the game behaves differently. The possible values are: Bet multiplier 15x - the chance to win the FREE SPINS round naturally is higher. More SCATTER symbols are present on the reels. The BUY FEATURE is disabled. Bet multiplier 10x - Normal play.

Big Bass Mission Fishin: Pick Your Path Before the Bonus Begins

Setting the Scene Underwater

This entry goes nocturnal, with the Fisherman trading his boat for a deep dive after dark. The reels are nestled among streams of rising bubbles in dark blue water, and the symbols get quasi-secret-agent tweaks that lean into the sneaky, after-hours mood. Card royals from 10 to A wear fishing lures, while the higher-value symbols stick with the theme through tackle, hats, rods and the familiar bass. The result is a moodier, spy-tinged take on the series that suits a game built around waiting for the right moment to strike.

Layout and How Wins Land

This is a straightforward five-reel, three-row grid with 10 fixed paylines. Matching symbols pay from the leftmost reel rightwards along those set lines, so there is no need to manage active lines yourself. Stakes run from 0.10 per spin, which keeps the game open to cautious players and high rollers alike. The real payoff, though, is made in the bonus rather than the base game.

The Mission Mechanic

The Fisherman acts as the wild, landing on reels 2, 3 and 4 and substituting for regular symbols. The bonus itself is triggered by landing 3 or more buoy scatters anywhere on the reels. When only 2 scatters hit, there is a chance the third is dragged in by a hook or by a respin, giving near-misses an extra shot at the feature. Once the bonus triggers, you choose your mission: take the Free Spins round or switch the game over to Stack the Cash. Picking between the two becomes a genuine call rather than a formality.

Free Spins and the Collector Upgrade

Choose Free Spins and you first pick from a set of files to reveal modifiers, such as More Fish, More Fisherman or extra spins, with the picks continuing until a boot turns up. During the round each Fisherman Wild collects the values of all the Fish Money symbols in view and pays the total. The upgrade runs on a progressive level system tied to the wilds you collect: every 4th wild awards more free spins and raises the multiplier, climbing through 2x and 3x to 10x as the levels build. Stack those upgrades and a quiet bonus can turn into a serious haul.

Stack the Cash Hold and Win

The alternative is Stack the Cash, a hold-and-win round where only Fish Coin symbols and blanks land. Each coin carries a value of up to 25x the bet and sticks in place, and every time one lands the respin counter resets to 4. When a reel fills, its values are banked by the robo-crab and the reel reopens, while a bomb can drop onto a random reel to double the value of every Fish Coin on it. The collected values are paid out once the respins run dry.

RTP, Volatility and Win Ceiling

Big Bass Mission Fishin ships with a default RTP of 96.5%, slightly above the industry norm, with lower 95.5% and 94.5% configurations available at some operators. It is a high-volatility game, so expect uneven sessions with longer gaps between meaningful wins. The reward for that patience is a maximum win of 5,000x your stake, reached when the high-value fish and the collector multiplier align during the bonus.

Where It Sits in the Big Bass Range

If you already know the series, the rhythm here will feel familiar, but the bonus choice sets it apart. Fans can compare it directly with the original Big Bass Bonanza, the wilder Big Bass Splash, or the crash-style spin on the formula in Big Bass Crash. All share Pragmatic Play's clean production.

Trying the Free Demo

The free demo at Slottomat is the best way to learn the trade-off at the heart of this slot. Trigger the bonus a few times and test both paths to see how the Free Spins multiplier builds against a full board of Stack the Cash coins. With no stake at risk you can settle on a preferred approach before deciding whether the high-volatility ride suits you.

There is no "mission" minigame that lets you pick how many fish to catch. The bonus is triggered by landing 3 or more Scatter symbols, which awards 10, 15 or 20 free spins. When the bonus triggers you then choose between two different rounds: standard Free Spins or the Stack the Cash Hold & Win feature. If you pick Free Spins, you select "files" to reveal boosters (such as More Fish, More Fisherman, Start from Level 2, extra Dynamites/Hooks/Bazookas, or +2 spins) until a Boot ends the selection. During the spins the Fisherman Wild collects Fish Money values, and a progressive multiplier rises as more wilds are collected.

The maximum win in Big Bass Mission Fishin is 5,000x your stake. It is a medium-volatility slot, and the ceiling is reached only rarely - typically during the Free Spins bonus when the Fisherman Wild collects high-value Fish Money symbols and the progressive multiplier has climbed to its higher levels. The alternative Stack the Cash Hold & Win round, with its sticky Fish Coins and bomb multipliers, can also build toward big wins.

During the Free Spins round the Fisherman Wild appears on all reels and special reels are in play. Each Fish carries a cash value, and when a Fisherman Wild lands it collects the values of all Fish symbols currently on screen and awards the total. The wilds also drive a progressive multiplier: as you collect more Fisherman Wilds you climb through multiplier levels, increasing the value applied to future collections for the rest of the round. Note that Free Spins is one of two bonus options - when the bonus triggers you can instead choose the Stack the Cash Hold & Win round.
