Pull a Lucky FishWelcome to the definitive breakdown of one of the most misunderstood mechanics in Pull a Lucky Fish. Whether you're trying to hook a Voidfish or simply want to stop pulling up endless schools of Colorless Fish, understanding the game’s luck system is the key to unlocking the rarest catches. Many players assume that simply casting into the Far Water is enough, but without stacking your luck multipliers, you’ll be grinding forever. This guide explains exactly how Fish Luck differs from Mutation Luck, how they stack with your rod, and the most efficient way to configure your loadout.
The Two Types of Luck Explained
The luck system in Pull a Lucky Fish is split into two distinct categories. New players often confuse them because both are sold as gamepasses, but they affect entirely different stages of your catch. The first category is Fish Luck, which governs the rarity tier of the fish you hook. The second is Mutation Luck, which determines whether that fish transforms into a higher-value variant after it’s already on your line.
Fish Luck activates the moment your bobber hits the water. The base game has an internal rarity table ranging from trash items up to Secret-tier fish like the Voidfish. Without any boosts, the odds of encountering a Mythic or Legendary fish are, according to community reports, estimated to be below 1%. The x2 Fish Luck gamepass (225 Robux) doubles your probability of moving up into these higher rarity brackets. However, it’s not a flat "double the fish" mechanic; it modifies the weight of the dice roll. This means that if a Prism Fish has a base spawn chance of 0.5%, a doubled luck stat pushes it closer to 1%. This bonus stacks multiplicatively with the hidden luck stats on your fishing rod.
Mutation Luck, on the other hand, doesn't care about what fish you hooked. It checks for a mutation after you successfully reel in a catch. The x2 Mutation Luck gamepass (360 Robux) doubles the chance that your fish will undergo a beneficial transformation, like turning into a Bloody or Moon-linked variant. These mutated fish generate significantly more passive income once banked on your island. If you consistently catch Epic-tier fish but want to maximize their value without relying on the ultra-rare Secret-tier spawns, prioritizing Mutation Luck is a valid strategy.
How Rods and Training Influence Luck
Your choice of rod is the silent backbone of your luck strategy. While the gamepasses provide a visible multiplier, your rod provides the base stat that gets multiplied. Currently, the community has identified three primary end-game rods, though their exact stats are still a subject of debate. The Ice Rod, which costs roughly 50 million cash according to player estimates, is widely reported to possess an inherent ~2.5x luck multiplier. This is an unverified community estimate, but testing suggests it significantly increases the appearance of Legendary-tier fish like the Dolphin and Sunfish.
The Crow Rod and Thunder Rod are also in the meta, though their exact luck values remain unverified. If the Ice Rod’s 2.5x luck is accurate, pairing it with the x2 Fish Luck gamepass doesn't just give you a 5x luck boost. The game likely processes the rod’s luck first, determining your base rarity, and then the gamepass modifier re-rolls or adjusts the weight again. This double-dipping is why some players seem to catch Voidfish and Alien Fish with relative ease. Without a high-tier rod, the x2 Fish Luck gamepass alone is far less effective because it’s doubling a very small base number.
Pull Power is also indirectly tied to your luck. The x2 Pull Power gamepass (99 Robux) allows you to reel in fish faster. While this doesn’t change the rarity of the fish, it drastically reduces the time the shark has to steal your catch. A stolen fish has a 0% chance of being banked. Therefore, increasing your pull speed gives you more successful cash-outs per hour, increasing the volume of "dice rolls" you get to make. More casts equal more opportunities for your luck stat to trigger.
| Gamepass | Price (Robux) | Effect |
|---|---|---|
| x2 Fish Luck | 225 | Doubles the chance of hooking higher rarity fish |
| x2 Mutation Luck | 360 | Doubles the chance of a mutation appearing on a caught fish |
| x2 Pull Power | 99 | Halves the time required to reel a fish to shore |
| x2 Cash | 360 | Doubles the cash value of sold fish |
| Auto Fishing | 49 | Automatically casts the line |
Maximizing Passive Income Through Rarity
The entire point of boosting your luck is to generate passive income from your island. When you bank a fish, its rarity tier directly determines the cash-per-second it generates. A Colorless Fish (Epic-tier) provides a modest baseline, but a Voidfish (Secret-tier) can single-handedly carry your economy. The hierarchy of known fish is critical for understanding what you're aiming for.
Secret-tier fish like the Voidfish and Prism Fish are the ultimate goals. They are only reliably found in the Far Water, which requires significant investment in casting distance training. If you can’t reach the Far Water, you are locked out of the highest luck bracket. Mythic-tier includes the Alien Fish, which is a strong bridge between the mid-game and the end-game. Legendary-tier fish like the Dolphin and Sunfish are your bread and butter for mid-game income, while Epic-tier fish like the Codfish and Colorless Fish help you stabilize early on.
To maximize your passive income, you shouldn't just bank every fish you catch. The shark mechanic is designed to punish greed. After every catch, the shark enters the water and chases the player. If you are holding a high-value fish, it’s often better to bank immediately rather than risk a longer cast to the Far Water while holding a Prism Fish. A Voidfish in the bank is worth infinitely more than a Voidfish in the shark's stomach. The x2 Cash gamepass (360 Robux) doubles the final passive income output, but it does not help you catch the fish. You need the luck mechanics to secure the fish first.
Mutation Stacking Strategies
Mutations in Pull a Lucky Fish are the final multiplier on your income. The two known mutations, Bloody and Moon-linked, are high-value variants that overlay a special visual effect on your fish. Because mutations apply after the catch, they are the most efficient way to boost the value of lower-tier fish. A Legendary Dolphin with a Moon-linked mutation might generate more passive income than a base Alien Fish.
The strategy here involves the x2 Mutation Luck gamepass. If you are running a speed-farming build (focusing on casting speed and pull power to catch high volumes of fish), Mutation Luck provides more consistent value than Fish Luck. You will inevitably catch many Epic-tier fish. Without Mutation Luck, these are low-value fillers. With Mutation Luck, a significant percentage of them will transform into high-value assets.
Here is a breakdown of the known fish and their general utility:
| Fish Name | Rarity | Utility |
|---|---|---|
| Voidfish | Secret/S | Max passive income, extremely rare |
| Prism Fish | Secret/S | Max passive income, extremely rare |
| Alien Fish | Mythic/A | High passive income, Far Water |
| Dolphin | Legendary/A | Strong mid-to-late game passive income |
| Sunfish | Legendary/A | Strong mid-to-late game passive income |
| Codfish | Epic/B | Stable mid-game filler |
| Puffer Fish | Rare/B | Early-game income |
| Colorless Fish | Epic/B | Common Far Water filler |
Gamepass Priority and Optimization
If you are investing Robux, the order in which you purchase gamepasses drastically changes your progression speed. Many players rush to buy the luck passes without the infrastructure to support them. Consider this priority list based on the "volume vs. value" theory.
First, Auto Fishing (49 Robux) is the cheapest and most effective quality-of-life purchase. It allows you to accumulate fish over long periods without active input, which is essential for overnight grinding. However, auto-fishing alone doesn't optimize the value of the fish. The second purchase should be x2 Pull Power (99 Robux). This synergizes with auto-fishing by ensuring the automated casts are brought in quickly, reducing the chance of the shark stealing the fish while you are AFK.
Only after securing the speed and automation mechanics should you invest in the luck gamepasses. The x2 Fish Luck (225 Robux) is generally more impactful than x2 Mutation Luck (360 Robux) because raising the base tier of the fish (e.g., from Legendary to Mythic) is a bigger mathematical leap than mutating an Epic into a mutated Epic. However, if you already have the Ice Rod with its estimated 2.5x luck, the Mutation Luck pass becomes more valuable as you are already catching high-tier fish regularly. The x2 Cash pass (360 Robux) is a "win-more" purchase, best bought last when your island is already full of high-tier fish.
To summarize the community-verified data points and unverified estimates, here is a reference table for the rods currently known in the game:

FAQ
Does the x2 Fish Luck gamepass guarantee a Secret fish?
No. The x2 Fish Luck gamepass modifies the probability weight of the rarity table. If a Voidfish has a base probability of, say, 0.1%, the x2 boost raises it to roughly 0.2%. It is still a very low probability, but it is mathematically twice as likely as before. You still need to reach the Far Water and use a high-tier rod to make the base chance viable.
Is the Ice Rod better than the Crow Rod?
According to community reports, the Ice Rod is currently the best rod for luck, with an estimated 2.5x multiplier. The Crow Rod and Thunder Rod exist in the game, but their specific luck values are unverified. Until the community data-mines the exact stats or Openwater Games releases official numbers, the Ice Rod is the safest investment for a luck-focused build.
Can I get a Voidfish without any gamepasses?
Technically, yes. The game’s base rarity table allows for any fish to be caught with the default rod and zero gamepasses. However, the probability is so low that it is statistically improbable. Without the x2 Fish Luck gamepass and a high-tier rod, you would need an extraordinarily high volume of casts. It is more efficient to reinvest cash into the Ice Rod first, as its inherent luck boost applies for free once purchased.
Does Mutation Luck affect the chance of catching a Secret fish?
No. Mutation Luck only activates after a fish has been caught. It does not influence the type of fish that bites the hook. It decides whether that fish will have a Bloody or Moon-linked visual and value upgrade. To catch a Secret fish like the Prism Fish, you must rely solely on Fish Luck and your rod's base luck stat.
