Marlin Masters: Slot Overview
Showing once again how hard it is to resist, the fishing-slot niche has hooked another studio—Hacksaw Gaming. The developer has mostly stayed away from this well-worn style, but this time the lure was too tempting, giving fish-slot fans another title to cast their line at. Called Marlin Masters, it arrives in the wake of two heavyweights of the genre, Fishin’ Frenzy and Big Bass Bonanza, combining fish cash-symbol collecting with a progression-driven free spins feature.
If you jumped into Marlin Masters without any context, you might not immediately peg it as a Hacksaw Gaming release from the visuals alone. It doesn’t lean into the studio’s ultra-cute vibe (Canny the Can, etc) or its darker, more intense side (Hand of Anubis, etc). Instead, Marlin Masters sits in a fairly neutral visual lane, matched by features that also feel broadly middle-of-the-road. It seems likely Hacksaw Gaming is aiming Marlin Masters at a mainstream crowd, though players beyond that bracket may still find some enjoyable fishy action here.

Balanced a little nervously at the edge of a boat, Marlin Masters uses a 5×4 gaming grid with 14 paylines to determine wins. The paytable doesn’t deliver massive line-hit values, though, so the real emphasis is on landing and collecting Marlin cash symbols. Bets, hooks, and all that run from 10 c to $/€100 per spin, and anyone who prefers to fast-track the action has five bonus buys available. Volatility floats around the middle too, coming in at medium, while the top RTP is 96.24% when playing with standard wagers.
There are four fish symbols at the top of the paytable in Marlin Masters, paying 5x to 7.5x for landing 5 of a kind. Below them sit the 10-A card royals, which return 2x the bet for a 5 OAK result. Interestingly, the Fisherman symbol isn’t wild in Marlin Masters, but the anchor symbol is. It can replace any regular paying symbol. Wilds can appear on all reels and award 10x for 5 OAK.
Marlin Masters: Slot Features

Anyone familiar with fishing slots will find Marlin Masters’ features feel very recognizable—like revisiting a well-known story. You get Lootlines, Cash Them All! for awarding fish money symbols, plus three bonus rounds—Reel It In, Off The Hook, and Plenty Of Fish In The Sea—along with bonus buy options.
Lootlines and Cash Them All!
Marlin symbols are pay symbols that show cash values. These values range from 1x the bet up to 1,000x. Marlin symbols are collected when 3 or more land as part of a winning payline combination, in 4 Fantastic Fish fashion. Also, if at least one Fisherman symbol is on screen, each Fisherman symbol collects the values of the Marlin symbols as well. The Fisherman symbol may land with a multiplier value of x1 to x20, which boosts the Marlin values it collects.
Reel It In
Reel It In awards 10 free spins after landing 3 FS scatter symbols in the base game. This mode includes a Marlin Progress Bar. Every time a Fisherman appears—whether it collects cash or not—it progresses the Marlin Progress Bar by +1 step. Once every 4 Fisherman symbols have landed, play advances to the next level:
- Upgrade 1 awards 10 additional free spins and ensures all future Fisherman symbols land with a multiplier of at least x2.
- Upgrade 2 awards 10 additional free spins and ensures all future Fisherman symbols land with a multiplier of at least x4.
- Upgrade 3 awards 10 additional free spins and ensures all future Fisherman symbols land with a multiplier of at least x10.
Off The Hook
This bonus, along with 15 free spins, is triggered by landing 4 FS scatters in the base game. Off The Hook follows the same general idea as Reel It In, but Fisherman symbols are guaranteed to have a multiplier of at least x2 right from the beginning, and the upgrade levels are stronger.
- Upgrade 1 awards 15 additional free spins and ensures all future Fisherman symbols land with a multiplier of at least x4.
- Upgrade 2 awards 15 additional free spins and ensures all future Fisherman symbols land with a multiplier of at least x10.
- Upgrade 3 awards 15 additional free spins and ensures all future Fisherman symbols land with a multiplier of at least x15.
Plenty Of Fish In The Sea
Landing 5 FS scatters in the base game starts this bonus with 10 free spins. During this feature, all Marlin symbols are guaranteed to have values of at least x5. Every spin is guaranteed to land at least one Marlin and one Fisherman.
Bonus Buys
Using the bonus buy, players can trigger BonusHunt FeatureSpins for 3x the bet, making each spin 5 times more likely to activate a bonus game. For 50x the bet, each spin is guaranteed to land at least two Marlins and one Fisherman. For direct entry into the bonus rounds, Reel It In costs 65x, while Off The Hook costs 200x to activate.

Marlin Masters: Slot Verdict
It’s difficult not to feel like you’ve encountered much of this before, though that’s a pretty typical response after covering lots of fishing slots. Marlin Masters leans into the familiar “land a Fisherman symbol to collect fish money symbols” mechanic, which is practically everywhere in this category. It’s an easy fit thematically—people head out on the water to catch fish in real life—so it translates neatly into slot form. This style of game has stayed hugely popular for a long time, driven both by player demand and by designers’ eagerness to keep producing variations on the theme.
Hacksaw Gaming has joined in, and while its take isn’t exactly groundbreaking, there are tweaks here that could appeal to dedicated angling-slot players. For one, Fisherman symbols can show up throughout the game, not only in free spins, and they can carry a multiplier at any point. It’s also not especially common to see more than one bonus round, which gives persistent players something extra to chase and gives bonus buyers a choice—go for the standard free spins option or take a shot on the pricier upgraded version. Inevitably, comparisons to Big Bass Bonanza come up, and Marlin Masters felt more reluctant to drop Fisherman symbols during free spins. That’s based on general feel rather than published stats, but landing Fisherman symbols and pushing upgrades seemed tougher than in a Big Bass title—though of course results can vary from player to player.
Still, because Fisherman symbols can arrive with a multi at any time, a single strong spin in either the base game or a bonus can deliver a very healthy catch. And with a maximum win of 7,500x available across all game modes, Marlin Masters stacks up respectably against its closest rivals. Overall, it’s an unusual-feeling release given the studio behind it, yet it’s a solid enough entry in the ever-growing fishing-slot collection.
