Big Mouth Fishin’ Slot Review

If we had a dollar for every fishing-themed slot released post-2020, we would be retired on a beach doing our own fishing spot by now. The popularity of the Big Bass Bonanza game, released by Pragmatic Play in 2020, has seen an industry-wide pile-on to the fishing genre, with every studio casting their rods and seeing how many players they can catch. OROS Gaming, a partner studio of Games Global, did just that with Big Mouth Fishin’, a fishing-themed bonus with a selection of bonuses and the chance to win 5,000x your stake. Is this a good catch, though? We are going to find out in this Big Mouth Fishin’ slot review.

Big Mouth Fishin’ Online Slot Game Design

We found the Big Mouth Fishin’ slot nicely designed, if not a little uninspired. Fishing slots have a fairly well-established blueprint, and Big Mouth Fishin’ does little to challenge that. The reels are set just beneath the surface of the ocean, with coral and other sea plants floating around to the side of the reels. 

In terms of symbols, the game uses all of the standard imagery for a fishing slot. This includes a fishing boat, a reel, some fish, and various other pieces of equipment. From a graphics standpoint, we thought the slot looked impressive, and it was nicely complemented by a simple but effective soundtrack that didn’t have us immediately reaching for the mute button. 

Playing Big Mouth Fishin’ Slot on Mobile Devices

For our review, we tested the Big Mouth Fishin’ slot on an iPhone and an Android tablet. The experience on both was excellent, with the slot’s colorful design lending itself nicely to mobile playing sessions. To get the best from the experience, you will want to play the game in landscape mode at top mobile casinos or apps.

Big Mouth Fishin’ Online Slot Gameplay Features

Like the action of fishing itself, we found getting started with the Big Mouth Fishin’ online slot game nice and easy. The slot uses five reels and three rows, with 25 fixed paylines on each spin. Winning combinations are formed when you land three or more matching symbols from left to right, starting on the leftmost reel. 

The stake is adjusted below the reels. The minimum stake is $0.10, and the maximum is $20, a betting range that we found quite limiting, especially if you are a high-stakes player. However, you can activate the Link & Win booster and get your max bet up to $50.

Big Mouth Fishin’ Online Slot Bonus Features

There are two main bonuses in the Big Mouth Fishin’ slot - the Link&Win game and the free spins round. To trigger the Link&Win bonus, you must land six or more instant-win fish symbols. When this happens, they will hold in place, and players will get three respins. Whenever a new symbol lands, it will also lock in place and will reset the spin count to three. 

During the round, you can get one of four jackpots. The Mini, Minor, Major, and Mega Jackpots are worth 50x, 150x, 750x, and 5,000x your stake, respectively. The first three can all land on the reels during the round, but you will need to fill all 15 positions on the grid to win the Mega Jackpot. 

The other bonus is a standard free spin round. This is launched when you land three or more scatters across the middle of three reels. Players get ten spins, and during the round, the middle three reels are merged, creating one giant symbol and significantly boosting the game’s winning potential. The giant block counts as nine individual symbols. 

Finally, you can boost your chance of triggering the Link&Win bonus by activating the Booster Bet option. This is an ante-bet feature that can be activated for 1.5x your stake, increasing your wanger to $50.

Big Mouth Fishin’ Slot RTP, Maximum Payout & Volatility

The maximum win in Big Mouth Fishin’ is the Mega Jackpot, which is worth 5,000x your stake. The game has an RTP of 96.08%. The slot is considered highly volatile, which we found to reflect our experience when playing. We waited long periods between wins, with the bonus feature only launched when we activated the Booster Bet. 

Big Mouth Fishin’ Slot Summary

Overall, we found Games Global's Big Mouth Fishin’ to be a good, if slightly forgettable, addition to the fishing genre. The game is nicely designed but does little to stand out among other titles in the genre. Link&Win makes for some fun gameplay, though, and the Booster Bet option is a particularly useful way to boost your chances of entering the bonus round and is much more budget-friendly than an outright buy bonus feature.
