What’s different about the Mission Fishin’ compared to other Big Bass slots?

Big Bass Mission Fishin’ stands out for its clean layout, fast reel spin, and direct bonus structure. We designed it as a high-volatility game for players who prefer straightforward high-risk slots.

If Big Bass Bonanza is a relaxed weekend on the lake, this one feels like a timed mission – quick rounds, higher stakes, and less downtime between key features.

Our slot is popular among British players thanks to its unpredictable payouts and the ability to launch bonus rounds with minimal spins. It runs equally well on desktop and mobile devices.

Theme & Graphics

The game uses a simple underwater theme with a bit of a spy vibe. Look closely during wins and you’ll see the fisherman adjust his “mission goggles” – a nice touch that most players miss on mobile.

All symbols are sharp and easy to follow, even on mobile. We kept animations minimal so you can focus on the reels without distractions.

RTP and Volatility

Big Bass Mission Fishin’ has an RTP of 96.5% and is classified as a high volatility slot. That means wins may not land often, but when they do, they can reach up to 5000x your bet in a single round. For context, that RTP is slightly above the average for high-volatility Pragmatic Play titles, which sit closer to 96.3%.

This setup suits players looking for larger but less frequent payouts.

Slot Symbols

Symbol payouts are split across premium, mid-tier, and low-value categories. The game also includes a Wild and Scatter symbol that trigger key features.

Wild Symbol

Substitutes for all symbols except Scatter

Scatter Symbol

Triggers Free Spins (3 or more required)

The Wild appears only during free spins and helps complete winning combinations. The Scatter symbol unlocks bonus rounds when 3 or more land anywhere on the reels.

Slot Features and Bonus Rounds

Our slot includes several features designed to boost potential payouts and keep gameplay dynamic. You’ll find free spins, multipliers, cash symbols, and side bets – all built into a fast-paced bonus system that doesn’t require long wait times to trigger.

Money Symbol

Fish symbols act as Money Symbols during both base game and bonus rounds. Each fish carries a random cash value from 2x up to 5000x your total bet, but these values are only collected during the Free Spins round.

There’s also a random feature in the base game when two Scatters land – either a hook can reveal a third Scatter or the reels shift to respin and try again. This is part of our new ‘no trigger’ bonus system, which we’ve added to the newer slots – and Big Bass Fishing Mission is no exception.

Free Spins

You can trigger the Free Spins feature by landing 3, 4 or 5 Scatters, which awards 10, 15, or 20 free spins. Before the round begins, you’ll select random items on the screen to unlock modifiers – this continues until a boot symbol ends the selection phase.

Modifiers include options like more fish, more wilds, extra spins, or starting from level 2 in the progressive round. These additions increase your win potential without requiring extra bets.

Random Multipliers

Before Free Spins begin in our Mission Fishing Big Bass, fish symbols on the screen can randomly reveal multipliers from 2x to 5000x. These values are stored and only become active if collected during the bonus round.

This feature gives you an early look at potential big wins, setting the stage for high-payout spins without changing your bet size.

Stack the Cash Feature

During the Stack the Cash round, regular symbols disappear and only Fish Coins and blanks remain. Each Fish Coin carries a random value from 1x to 25x your total bet and sticks to the reels as long as new coins appear.

Every reel has a robo-crab that collects coin values. A bomb can drop randomly to double all coin values on a reel. The round ends when no more respins are left, and all collected amounts are paid out.

Ante Bet

The Ante Bet feature in the Big Bass Mission Fishin’ slot lets you raise your bet multiplier from 10x to 15x per spin. This increases the number of Scatter symbols on the reels, making it easier to trigger Free Spins – but disables the Buy Bonus option.

If you’re aiming to land bonuses naturally, activating Ante Bet gives you better odds without changing the RTP. You can toggle it on or off at any point during standard play.

Buy Free Spins

You can instantly trigger the bonus by purchasing it for 100x your total bet. After purchase, you choose whether to enter the Free Spins feature or the Stack the Cash round – both options are available from the same menu.

The Buy Free Spins option is disabled when Ante Bet is active, so you’ll need to switch back to regular play to open it. This feature is ideal for players looking to skip straight to bonus rounds.

How to Play Big Bass Mission Fishing

Playing the Big Bass Mission Fishin slot takes less than a minute to get started. Just follow these steps to register, place your bets, and spin the reels for a chance to win up to 5000x your stake.

“Some of the Big Bass sequels might look identical, but the hard fact is that each one has become a bestseller!

Hideous Slots

8.1/10

“Far from being a bad game, Big Bass Mission Fishin’ will have its fans and plenty of them. Who knows?…the addition of a second bonus feature may be the start of fresh ideas and mechanics to come down the line.

Bigwinboard

6/10

“By no means does Big Bass Mission Fishin’ push the BB franchise way on down the evolutionary pathway, but hey ho, reason enough for fans to dust off their virtual rod and reel for another bash.
