Dive deep for potential big wins in this fish-tastic slot adventure! Microgaming’s Big Mouth Fishin slot is a medium-to-high volatility game offering 25 paylines across five underwater reels and three rows. Set your winning waves in motion by catching the Free Spins feature and launching the Link&Win bonus game where four jackpots are waiting to be caught. Stay patient; the biggest catch can have you potentially luring in 5,000 coins in our online casino!

Big Mouth Fishin has a number of special features including Free Spins, the Link&Win feature, and a Bonus Game Enhancer. Let’s open this tacklebox of features and dive in.

Land three Scatters (the Fish Reel symbol) on the second, third and fourth reels to get awarded 10 free spins! For this round, the three middle reels will merge into a jumbo block, transforming the original 5x3 grid into a 3x3 one. If a Scatter lands within the new block, you’ll get an instant win and 10 extra spins added to your count. Plus, the free spins count will reset.

This feature is the star of the show in Big Mouth Fishin, and it’s available in both the main game and during the Free Spins feature. To trigger it, you’ll need to land at least six Cash symbols. Their values range from 20 coins to one of the four jackpots. The Mini jackpot pays 50 coins, the Minor 150 coins, and the Major pays 750 coins.

If this bonus game is activated, the original symbols that triggered it will become sticky and you’ll get three respins for the remaining positions. But, this will reset if you land another Link&Win bonus symbol. If you manage to populate all positions, you’ll take home the Mega jackpot of 5,000 coins, the game’s top prize!

The Win Boost works as an ante bet and it adds Link&Win symbols to the grid, boosting your winning chances. The paytable doesn’t change and the cost is 1.50x your wager.

Wins in Big Mouth Fishin are formed if you hit one of the game’s 25 paylines by landing adjacent symbols from the leftmost side of the grid. This slot game has 10 paying symbols and a Scatter that triggers the Free Spins feature. Cash symbols in the form of a bubble can also launch the Link&Win bonus round.

The game’s Wild is represented by a fishing boat and it is the highest paying symbol, awarding 500 coins if you land five of them!
The remaining symbols pay between 0.30 and 25 coins for landing a matching set of three to five.

Playing Big Mouth Fishin is straightforward to understand. Just wait for the game to load and set your wager once you’re in. Then use the big arrow button to spin the reels or the one below it for the auto-play mode. Much like fishing, auto play lets you sit back and wait.

If you’re looking to potentially boost your win, hit the blue arrow button on the bottom left side of the screen. Just below that is where you can access all the settings, including the paytable and game rules. The Big Mouth Fishin video slot is optimised for tablets and mobile phones.

Big Mouth Fishin was released in late 2023 by MicroGaming, known for their thematic and detailed video slot games. This isn't MicroGaming’s first fishing-themed slot, but its graphics and animation really make it stand out from the shoal. The background is dynamic, with algae and fish floating around in the distance in a scene completed by soothing waves. The Big Mouth Fishin slot game has a country-style soundtrack to listen to as you’re waiting on that big catch!
