Marlin Masters Atlantis

Marlin Masters Atlantis is an online slot developed by Hacksaw Gaming, released on April 23, 2026. It is the third entry in the Marlin Masters series, following Marlin Masters and Marlin Masters: The Big Haul. This installment blends the series' established fishing mechanics with an ancient Greek mythology theme, set in the legendary sunken city of Atlantis.

The game runs on a 5-reel, 4-row grid with 26 fixed paylines and offers a maximum win of 10,000x the bet, available across all game modes. It introduces the Kraken Collector, a new feature exclusive to this title, while retaining core mechanics from previous entries including Marlin Symbols, LootLines, and the Fisherman Symbol.

Key highlights include:

• Two free spin bonus games: Sunken Empire and Pose for Poseidon
• A progressive Trident Bar that upgrades the bonus with additional spins and higher multipliers
• Four Feature Buy options for direct bonus access
• Medium volatility with an RTP of 96.27%

Marlin Masters Atlantis is set against a bright, sun-drenched vision of the risen city of Atlantis. The backdrop features white marble columns, classical statues, and vivid blue skies – a departure from the open-water settings of the earlier Marlin Masters games.

The reel symbols are colourful and well-detailed. Fish symbols include a pufferfish, a red dragon fish, a goldfish, and a blue-striped fish. The Fisherman character returns with a trident in hand, fitting the Greek mythology setting. Jackpot Marlin symbols are golden-framed and visually distinct. Card royals (10, J, Q, K, A) fill the lower-value positions with clear, readable designs.

The overall presentation is polished and accessible – bright colours, clean animations, and a lively audio track that suits the underwater adventure theme. The Kraken Collector symbol, a small crowned creature, appears with an expanding animation that adds variety to the visual experience.

Marlin Masters Atlantis uses a standard layout that is straightforward to navigate. Set your bet using the controls at the bottom of the screen, ranging from 0.10 to 100 per spin. Spin the reels manually or activate autoplay for continuous rounds. The Buy Bonus button is available in the bottom-left corner for players who want to access bonus features or FeatureSpins directly.

Marlin Symbols and LootLines

Marlin Symbols are dynamic paying symbols that display a cash value on the symbol itself. The value shown represents the payout awarded if the Marlin forms part of a winning LootLine or is collected by a Fisherman Symbol.

A LootLine is formed when a winning payline consists of Marlin Symbols, Jackpot Marlin Symbols, or a combination of both. The total payout is the sum of the cash values shown on all Marlin Symbols within that winning line.

Marlin Symbol values are based on the following bet multipliers: 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, and 100x.

If a Marlin Symbol's value is too large to display in full, it is shortened to two decimal places. The displayed value is the minimum possible award – the actual amount may be higher.

Bonus Buy Option: Yes

Jackpot Marlins

Jackpot Marlin Symbols hold fixed jackpot values. When activated – either as part of a winning LootLine or by being collected by a Fisherman Symbol – the Jackpot Marlin reveals one of four fixed jackpot values:

• Mini: 25x bet
• Major: 100x bet
• Mega: 500x bet
• Max Win: 10,000x bet

Fisherman multipliers do not apply to Jackpot Marlin Symbols.

Bonus Buy Option: Yes

Fisherman Symbols

When a Fisherman Symbol lands, it collects all Marlin Symbols currently on the grid and awards their combined value as a cash prize. Fisherman Symbols activate after regular wins and LootLine wins have been paid.

Fisherman Symbols can also carry a multiplier value: x1, x2, x3, x4, x5, x10, x15, or x20. When present, this multiplier is applied to the total cash value of all collected Marlin Symbols before the prize is awarded. The multiplier does not apply to Jackpot Marlin Symbols.

Up to three Fisherman Symbols can land in a single spin. When multiple Fisherman Symbols appear, each one independently collects Marlin Symbols from top to bottom, left to right, and awards its own cash prize.

Bonus Buy Option: Yes (via FeatureSpins)

Kraken Collector

The Kraken Collector can only land on reel 1. When it lands, regular payline wins are handled first. The Kraken Collector then expands to cover the entire reel. All regular paying symbols are removed, leaving only Marlin and Jackpot Marlin Symbols in place. The reels then respin.

During the respin phase, only Marlin, Jackpot Marlin, and Dead Fish symbols can land. Marlin and Jackpot Marlin Symbols that land become Sticky and remain in position. Dead Fish symbols are blank – they do not contribute to wins. Respins continue until no new Marlin or Jackpot Marlin Symbols land. Once the final respin is complete, all Sticky Marlin and Jackpot Marlin Symbols are collected, and their combined value is awarded as a cash prize.

Jackpot Marlin Symbols reveal their value only when the final respin is complete. Marlin and Jackpot Marlin Symbols cannot land on the same reel as the Kraken Collector. Fisherman Symbols cannot appear during the same spin as a Kraken Collector.

Bonus Buy Option: Yes (via Noisy Neptune FeatureSpins)

Bonus Game – Sunken Empire

Triggered by landing 3 FS Scatter Symbols simultaneously during the base game. Awards 10 free spins.

This bonus game keeps all base game mechanics active. In addition, a progressive Trident Bar is displayed at the top of the grid. Each time a Fisherman Symbol lands, the Trident Bar advances by one step – regardless of whether the Fisherman collects any Marlins that round.

After every fifth Fisherman Symbol lands, the bonus upgrades to the next level:

• Upgrade 1: 8 additional free spins; all subsequent Fisherman Symbols land with a multiplier of at least x2.
• Upgrade 2: 8 additional free spins; all subsequent Fisherman Symbols land with a multiplier of at least x3.
• Upgrade 3: 8 additional free spins; all subsequent Fisherman Symbols land with a multiplier of at least x5.

Bonus Buy Option: Yes (Cost: 100x bet)

Bonus Game – Pose for Poseidon

Triggered by landing 4 FS Scatter Symbols simultaneously during the base game. Awards 15 free spins.

This bonus uses the same mechanics as Sunken Empire, including the progressive Trident Bar, but starts with a higher chance of reaching the upgrade levels. This gives the bonus greater potential for extended spins and elevated multipliers.

Bonus Buy Option: Yes (Cost: 200x bet)

FeatureSpins

The game also offers two FeatureSpin options that modify the base game rather than jumping straight to a bonus round:

• BonusHunt FeatureSpins (Cost: 3x bet per spin): Each spin has approximately five times the normal chance of triggering a bonus game. FS Scatter Symbols cannot land during this mode.
• Noisy Neptune FeatureSpins (Cost: 50x bet per spin): Each spin guarantees one Kraken Collector Symbol and one Marlin Symbol on the grid.

Both FeatureSpin modes remain active until manually disabled.

Wins are formed by landing three or more matching symbols on adjacent reels from left to right, starting from reel 1, across one of the game's 26 fixed paylines. Marlin Symbols and Jackpot Marlin Symbols pay through the LootLines mechanic, with payouts based on the cash values displayed on each symbol.

The Wild Symbol substitutes for all symbols in the paytable.

Special Symbols:

• Wild: Substitutes for all symbols in the paytable.
• Marlin Symbol: Displays a cash value. Pays via LootLines or when collected by a Fisherman Symbol. Values range from 1x to 100x the bet.
• Jackpot Marlin Symbol: Holds a fixed jackpot value (Mini, Major, Mega, or Max Win). Activated via LootLine wins or Fisherman collection.
• Fisherman Symbol: Collects all Marlin Symbols on the grid. Can carry a multiplier up to x20.
• Kraken Collector: Lands on reel 1 only. Expands to cover reel 1 and triggers a respin phase.
• FS Scatter: Landing 3 triggers Sunken Empire (10 free spins); landing 4 triggers Pose for Poseidon (15 free spins).
• Dead Fish: Appears only during Kraken Collector respins. A blank symbol with no win value.

Marlin Masters Atlantis uses 26 fixed paylines. Wins are paid left to right from reel 1 using matching symbols on adjacent reels.

Beyond standard payline wins, the main win driver is the LootLines mechanic. When a payline consists of Marlin or Jackpot Marlin Symbols, the total payout is determined by the sum of the cash values on those symbols – not a fixed multiplier table. This means each LootLine win can vary significantly depending on the values displayed.

Fisherman Symbols collect all Marlin Symbols on the grid after standard wins are resolved, adding an additional cash prize. A multiplier on the Fisherman Symbol (up to x20) scales the collected total further.

The Kraken Collector triggers a respin phase where Marlin and Jackpot Marlin Symbols accumulate in sticky positions before a final collection payout.

In the bonus games, the Trident Bar can upgrade Fisherman multipliers progressively, raising the minimum multiplier to x2, x3, or x5 as upgrades are reached.

Marlin Masters Atlantis is the third game in Hacksaw Gaming's Marlin Masters series. The two earlier titles share the same core mechanics – Marlin Symbols, LootLines, and Fisherman collection – but differ in setting and feature additions.

• Marlin Masters – The original entry in the series. Open-water fishing theme, high volatility, and a max win of 7,500x the bet.
• Marlin Masters: The Big Haul – The second release. Retains the series' mechanics with expanded bonus content and a higher max win potential.

Players familiar with the Big Bass series or fishing-themed slots from providers like 4ThePlayer will find the Marlin Masters format recognisable.

Marlin Masters Atlantis delivers a well-structured fishing slot with a mythology-themed presentation and a solid feature set. The combination of LootLines, Fisherman collection, and the Kraken Collector creates varied gameplay within each spin. The progressive Trident Bar in the bonus games adds an escalating element that keeps the free spins rounds engaging. With medium volatility, a 96.27% RTP, and a 10,000x max win available in all game modes, the game suits players who prefer moderate risk with meaningful upside. The feature set is feature-rich rather than groundbreaking – players new to the Marlin Masters series may need a few spins to fully understand how the mechanics interact.
