Big Mouth Fishin Slot Review
You’re at the bottom of a sunlit lake, looking up: green-gold swells rippling across the top of the screen, a patch of blue sky showing through, kelp fronds curling up either side of the reels and bubbles drifting past the frame. Big Mouth Fishin spends its entire bonus budget on the middle three reels, and once you notice that, every part of the game makes sense. Reels 1 and 5 are scenery; the money and the ideas all swim through the centre.
Jjackpot plaques stacked down the left sit on coral-weed brackets, a small largemouth bass poking out beside each name. Oros Gaming has built real character into a familiar theme. The stats: a 5×3 grid with 25 fixed paylines, 96.08% RTP rising to 96.33% with the Win Booster, high volatility, a 30.33% hit frequency, stakes from 0.10 to 20.00. Sister titles Cash Spree Fishin’ and Magnificent Power Leprechaun share the same chunky feature design; this one goes after the bass.
Base Game & Features
It’s a 5 reel, 3 row video slot with 25 fixed paylines. Wins pay left to right from the first reel. When multiple winning combinations land on a single payline, only the highest one counts.
The total payout is the sum of all payline wins and scatter wins from a spin. Only the highest winning combination is awarded per symbol combination, so stacked lines of the same symbol don’t stack payouts. Nothing exotic hides in the base rules.
Payline wins are based on your total bet, and the values in the paytable are multiples of that full stake.
Wild symbols substitute for everything except the Link&Win and Free Spins symbols, and they can form their own winning combinations on a payline. The Free Spins symbol is a scatter that appears on reels 2, 3 and 4 only, paying in any position.
The middle three reels carry all the feature weight as a result. Reels 1 and 5 never host a scatter, which shapes both bonus triggers and how the free spins round plays out. More on that below.
The paytable splits into picture symbols and royals, with one oddity: the Cola can is the second-best payer in the game despite looking like a low symbol. Values are multiples of the line bet:
- Fishing Lure/Fly: 1.2x, 2.5x, 15x for three, four, five
- Dragonfly: 1x, 2x, 10.5x
- Fishing Reel: 0.8x, 1.5x, 7.5x
- Cola/Can: 2x, 5x for three and four
- A: 0.5x, 0.8x, 4x
- K: 0.4x, 0.7x
- Q: 0.3x, 0.6x, 2.5x
- J: 0.3x, 0.5x, 2x
The top payout is 15x the line bet for five lures. That’s a modest ceiling by five-of-a-kind standards, and it tells you where the money in this game actually lives: the jackpot plaques and the respin feature, not the reels.
Win Booster
The Win Booster is a toggle you can switch on and off in the base game. It adds extra Link&Win symbols to the reels, increasing the chance of triggering the Link&Win feature without changing how any symbol pays. The terms:
- Extra bet: 1.5x the current bet, on top of the current bet
- Boosted stake: 2.5x the base amount per spin
- RTP: 96.33% boosted, against 96.08% without
The return only moves a quarter of a point, so the booster is really about how quickly you want to reach the respins rather than value. Your call before each session, since the toggle lives in the base game.
Link&Win and Free Spins in Big Mouth Fishin
Link&Win
Land six or more Link&Win symbols scattered anywhere on the reels and the feature triggers. Every triggering symbol is held in place. Each remaining position then spins individually, on special reels carrying only Link&Win symbols and blanks.
Three respins are awarded, and the count resets to three whenever a new symbol lands. A sticky run of symbols can keep the round alive for a long time, since every catch buys a fresh set of three. Blanks are the only thing that burns a respin.
Each Link&Win symbol carries a Cash Prize or one of the Mini, Minor and Major jackpots. Cash Prizes pay up to 20x your bet, and everything is awarded at the end of the feature rather than as you go. Fill every position with Link&Win symbols and the MEGA prize is awarded on top.
The feature ends when all positions are filled or the respins run out. Fifteen filled positions is the full-grid case that collects the MEGA. It can trigger in the base game and during Free Spins.
Free Spins
Three Free Spins symbols anywhere on the reels award 1x your total bet and 10 free spins. Free Spins symbols pay in any position, and that scatter win is added to any line wins from the triggering spin.
The twist is the Jumbo Block: reels 2, 3 and 4 combine into a single 3×3 mega symbol for the whole round. That’s where the middle-reel setup pays off, because one symbol landing in the block occupies all nine positions at once.
Land a Free Spins symbol in the Jumbo Block and you collect 10 additional free spins plus another 1x total bet. A Link&Win symbol in the Jumbo Block counts as nine individual symbols, which is the only realistic route to triggering the respin feature at full width.
Wins during the round are added to base game wins. Your bet, lines and Win Booster state are locked to whatever the triggering spin carried, so the booster can’t be switched mid-round. Plan that toggle before the scatters land.
Our Honest Verdict
Overall Rating: 7.2/10
Big Mouth Fishin is a slow drift with one big fish in it. The base game mostly marks time between features, and the reason to choose it over the dozen other respin slots on the same shelf is the free spins round, where the middle reels lock together and every spin carries real weight.
That Jumbo Block is the best thing here, and by a distance. It turns a standard 10-spin round into something with genuine swing, and the nine-symbol rule gives the respin feature a route in that most copies of this format simply don’t offer.
The paytable is the let-down: symbol values are thin and the real money is all parked in the jackpot ladder, so a session that never reaches the features pays very little. It suits fans of the Oros catalogue and anyone who enjoys a well-built respin round. Players chasing big line wins from the reels themselves have better water elsewhere.
Big Mouth Fishin FAQs
