Big Mouth Fishin’ Online Slot Review

Dive into the well-trodden waters of fishing themed games with the Big Mouth Fishin’ online slot from Games Global and Oros Gaming. It’s a 5-reel, 3-row, 25-payline game filled with bright symbols such as lures, dragonflies, and cans of beer.

It stands out from others with the fantastic bonus features. A wild fishing boat helps to complete wins, and a float triggers free spins with giant symbols across the middle reels. You can also launch a Link&Win respins feature where fish hold money values of up to 20x the stake and you can win jackpots worth up to 5,000x.

Big Mouth Fishin’ is a desktop and mobile game that has a high volatility matched to average returns of 96.08% at our recommended Pennsylvania slots sites and New Jersey slots sites.

How to Play the Big Mouth Fishin’ Slot

The high-quality graphics include animated waves and seaweed surrounding the reels. Symbols such as playing card emblems overlayed with hooks and ropes, reels, lures, and other fishing-themed items feature on the 5x3 grid. You’ll also find bonus symbols such as a fishing boat and green fish with money values attached. It’s a great example of this hugely popular topic that you can enjoy on PCs, Android, Windows, and iOS mobiles on your chosen Betting Apps.

You can dip your toes for just 0.30 per spin or dive in for a maximum stake of 20.00, with a tap on the plus & minus button revealing all options. A Win Booster costs 1.5x but adds extra bonus symbols to the reel strips. A lightning bolt button speeds everything up and the arrow in a circle unlocks automatic spins features.

You have 25 paylines here and win prizes with 3, 4, or 5 matching symbols across a line starting on the left. Click the 3 lines below the reels, followed by the ‘I’ tab to open a paytable and see how much each symbol pays at the selected stake. The beer can pays up to 25x the total wager, while the boat wild symbol acts as others if needed and is worth 500x if it fills a payline without substituting.

Free Spins & Other Features of the Big Mouth Fishin’ Slot Machine

There are two standalone bonus features here, with free spins and respins both available. Any 6 Link&Win fish symbols lock in place for 3 respins of the other positions. Fish hold money values of up to 20x the stake and only blanks, jackpot fish, or more money fish will land in respins. 

The number of spins resets to 3 any time fish appear, and the feature continues until you have 3 spins with only blanks, or the reels fill with fish. The Mini, Minor, and Major jackpot fish are worth 50x, 150x, and 750x the stake respectively. A Mega jackpot of 5,000x is yours if you manage to fill the whole grid with fish symbols.

You get 10 free spins from 3 or more float symbols landing at once. It’s easier to get big wins during the round as 3x3 Jumbo Block symbols fill the whole of reels 2, 3, and 4. If a Jumbo Block version of the Link&Win symbol appears it counts as nine symbols and triggers the respins, while the jumbo free spin symbol adds 10 retriggers the free games.

Big Mouth Fishin’ Slot Maximum Wins, Volatility, & Average Returns

Play the Big Mouth Fishin’ slot machine at the maximum 50.00 and claim the 5,060x maximum winning potential to win a prize of 253,000.00. It’s not the biggest win we’ve ever seen, but slightly more reachable as a result. 

This is a high volatility slot where the frequency of wins can be less than you get from lower variance games, but it’s a long-term trend and you can win a generous amount on any spin. The return to players calculation of 96.08% is right where we expect it to be in a high volatility slot. When the Boost Feature is activated, it can increase to 96.33%.
