Pull a Lucky Fish Rarity System Explained — From Common to Secret

Understanding the rarity system in Pull a Lucky Fish is the single most important factor in progressing from a beginner with a basic rod to a tycoon with a fleet of exotic fish circling your island. The game, developed by Openwater Games, hides its best catches behind multiple layers of probability, stat checks, and risk. This guide breaks down every tier, the mechanics behind each cast, and how to tilt the odds in your favor without wasting time in the wrong waters.

How the Rarity Tiers Work in Pull a Lucky Fish

Every fish you can catch belongs to a specific rarity tier, which directly determines its base cash value, its income generation rate when banked on your island, and the overall difficulty of the encounter. The game does not display exact percentage chances on screen, so the community has pieced together the probability structure through mass testing. According to community reports, the base rates before any luck modifiers are applied follow a steep curve that makes higher-tier fish genuinely rare.

The current known rarity hierarchy, from most common to rarest, includes Common, Rare, Epic, Legendary, Mythic, and Secret tiers. Each tier represents a different set of fish with escalating sell values and island income potential. The Common tier consists of generic small fish that serve as early-game filler. Rare and Epic fish start to provide meaningful cash injections, while Legendary and above represent the jackpot catches that can fund multiple upgrades in a single trip.

What makes the Pull a Lucky Fish rarity system unique is how it interacts with the shark chase mechanic. After every successful catch, a shark spawns and pursues you back to your island. If the shark catches you, it steals the fish you just caught. This creates a risk-reward dynamic where targeting rarer fish in far waters means a longer, more dangerous escape route. The rarity tier of the fish in your hands does not slow you down, but the psychological weight of losing a Mythic or Secret fish to the shark makes every return trip tense.

Community-Estimated Rarity Distribution

These figures are community-derived and not officially confirmed by Openwater Games. The actual numbers may shift slightly based on hidden mechanics, but the relative rarity gap between Epic and Legendary is the first major hurdle players notice. Catching your first Sunfish or Dolphin typically marks the transition from early-game struggle to mid-game stability.

Luck Mechanics and Probability Manipulation

Luck in Pull a Lucky Fish is not a vague concept — it is a concrete stat multiplier that directly modifies your rarity roll on each cast. The base game provides no innate luck bonus, meaning new players face the raw probability table with no assistance. Every source of Fish Luck you acquire multiplies the weight of higher-tier outcomes in your favor.

The primary sources of Fish Luck come from rods and gamepasses. The Ice Rod, priced at approximately 50 million in-game cash according to community reports, provides an estimated 2.5x Fish Luck multiplier. This single purchase dramatically shifts your catch distribution, making Epic and Legendary fish appear far more frequently. There are also unverified reports of Crow Rod and Thunder Rod existing in the game, though their stats remain unconfirmed as of July 2026. If they follow the pattern set by Ice Rod, they likely offer even higher luck multipliers or specialized bonuses.

The x2 Fish Luck gamepass costs 225 Robux and doubles your effective luck from all sources. This means an Ice Rod with the gamepass would provide approximately 5x total Fish Luck, pushing your probability curve heavily toward Legendary and Mythic catches. The x2 Mutation Luck gamepass, priced at 360 Robux, affects a separate roll for special mutations like Bloody or the rumored Moon-linked variant. These mutations add an additional rarity layer on top of the base fish rarity, creating ultra-rare combination catches worth exponentially more than their normal counterparts.

Fish Luck Sources and Effects

The stacking of luck sources creates an accelerating progression curve. Early game catches feel slow and unrewarding, but once you afford the Ice Rod and optionally purchase the gamepass, the floodgates open. Players who invest in both often report catching multiple Legendary fish per trip, whereas beginners might see one Legendary every ten to fifteen casts. This disparity is intentional, rewarding long-term investment and creating a satisfying power curve for dedicated players.

Far Water and Casting Distance Requirements

Rarity alone does not determine what you can catch — location matters equally. The game splits the fishing area into near water and Far Water. Near water surrounds the starting island and contains the full range of Common through Epic fish, with an extremely low chance at Legendary. Far Water, accessible only after investing in casting distance training, holds the game's rarest fish, including Mythic and Secret tier catches like Alien Fish, Voidfish, and Prism Fish.

Reaching Far Water requires significant investment in the training area. The casting distance stat determines how far your bobber lands from the island. Without any training, you are restricted to near water and will never encounter a Secret tier fish. The exact threshold for Far Water access is not publicly documented, but community testing suggests you need at least mid-level casting distance upgrades to consistently reach the zone where Mythic and Secret fish spawn.

The x2 Throw Power gamepass, priced at 229 Robux, doubles your casting distance, potentially allowing earlier access to Far Water without as many training upgrades. This gamepass becomes less impactful once you have fully upgraded your casting distance through training, but it provides a significant shortcut for players willing to invest Robux. The x2 Pull Power gamepass at 99 Robux affects a different mechanic — how quickly you can reel in a fish once hooked — which reduces the time spent in dangerous open water where the shark can intercept you.

Once you reach Far Water consistently, the rarity distribution shifts upward. According to community reports, the base chance for Mythic fish jumps from nearly zero in near water to approximately 3% in Far Water, while Secret tier fish become possible at all. The combination of Far Water access and high Fish Luck creates the optimal conditions for hunting Voidfish and Prism Fish, the two known Secret tier catches that represent the pinnacle of the game's collection.

Island Banking and Rarity-Based Income

Catching a rare fish is only half the equation. The island banking system converts your catches into passive income generators, and the rarity of the fish determines the income rate. Banking a Common fish adds a negligible trickle of cash, while banking a Voidfish or Prism Fish creates a massive passive income stream that funds future upgrades with minimal active play.

The income tier system rewards players who prioritize banking their rarest catches rather than selling them immediately. A Colorless Fish, despite being Epic tier, might sell for a decent lump sum, but banking it generates far more value over time. The decision to bank or sell creates interesting strategic choices. Early in your progression, selling a Legendary Dolphin or Sunfish might fund your Ice Rod purchase, after which you can catch replacement fish faster. Later, banking everything Legendary and above builds an income engine that makes cash concerns irrelevant.

The shark mechanic adds risk to the banking strategy. Every catch triggers a shark chase, and the shark steals the fish you are carrying if it catches you. This means the most valuable fish — the ones you most want to bank — are also the ones you are most terrified to lose during the escape sequence. The x2 Pull Power gamepass helps by reducing reel time, and the Faster Rolling gamepass at 229 Robux increases your swim speed during the escape, but neither eliminates the risk entirely.

Rarity to Income Conversion Table

Mutation System and Ultra-Rare Combinations

Beyond the base rarity tier, Pull a Lucky Fish includes a mutation system that applies an additional layer of rarity to certain catches. The two known mutations are Bloody and Moon-linked, though both remain unverified in their exact effects and appearance rates. A mutated fish retains its base rarity tier but gains a special visual effect and a significant multiplier to its value and banked income rate.

The Bloody mutation, according to community reports, adds a red tint to the fish and multiplies its value by an estimated 2x to 3x. A Bloody Sunfish would therefore sell for substantially more than a normal Legendary catch, and banking it would generate proportionally higher passive income. The Moon-linked mutation is even rarer, with only scattered reports of its existence. Some players claim it adds a blue-white glow to the fish, while others describe it as a spectral effect. Without official confirmation from Openwater Games, the exact nature of Moon-linked remains speculative.

The x2 Mutation Luck gamepass doubles the chance of any mutation applying to your catch. This gamepass is considered a late-game optimization, as mutations are rare enough that doubling a small chance still results in a small chance. However, for players farming Voidfish and Prism Fish, a mutated Secret tier catch represents the absolute peak of possible value — potentially the most valuable single catch in the entire game.

The interplay between rarity and mutations creates a two-roll system on each cast. First, the game determines the base fish rarity using your Fish Luck multiplier. Then, a separate roll determines whether a mutation applies, using your Mutation Luck multiplier. This means a mutated Secret fish is the rarest possible outcome, requiring both rolls to land in your favor simultaneously. The odds of catching a Moon-linked Voidfish are astronomically low, making it a true trophy for the most dedicated players.

Practical Progression Strategy Using Rarity Knowledge

Understanding the rarity system translates directly into an efficient progression path. New players should focus entirely on reaching Far Water access as quickly as possible. This means prioritizing casting distance training over rod upgrades initially, as even the best rod cannot catch Mythic or Secret fish in near water. The basic rod can technically hook a Secret fish if you manage to cast far enough, though the low luck stat makes this a lottery-level probability.

Once Far Water is accessible, the next priority becomes acquiring the Ice Rod for its approximately 2.5x Fish Luck multiplier. The 50 million cash price tag requires selling several Legendary catches, so early Far Water trips should focus on quantity over quality — catch everything, sell everything, and reinvest in the rod. After acquiring the Ice Rod, the game shifts dramatically. Your catch quality increases to the point where banking Legendary and above becomes sustainable, and your passive income engine begins to build.

For players willing to spend Robux, the most impactful purchases follow a clear priority order. The x2 Fish Luck gamepass at 225 Robux provides the single largest boost to progression speed. The x2 Throw Power gamepass at 229 Robux accelerates Far Water access significantly. The Auto Fishing gamepass at 49 Robux provides convenience but does not affect rarity directly. The x2 Cash gamepass at 360 Robux doubles your sell and income values but does not change what you catch — it is a multiplier on the output rather than the input, making it more valuable later in progression when you are already catching high-value fish regularly.

The game's 95% positive rating across 7.5 million visits reflects how satisfying this progression feels. Each rarity tier unlock — your first Epic Codfish, your first Legendary Dolphin, your first Mythic Alien Fish — marks a tangible milestone. The rarity system creates clear goals and rewards patience, while the shark mechanic ensures that even the most experienced players feel tension on every return trip with a Secret fish in hand.

FAQ

How rare is the Voidfish in Pull a Lucky Fish?

The Voidfish belongs to the Secret tier, the highest rarity classification in the game. According to community estimates, the base chance of catching any Secret tier fish is well below 1% without luck modifiers. With an Ice Rod and the x2 Fish Luck gamepass, the probability increases significantly but remains low enough that catching a Voidfish is a memorable event. The fish can only be found in Far Water, requiring substantial casting distance investment.

Does the Auto Fishing gamepass affect rarity?

No, the Auto Fishing gamepass does not directly affect rarity. It automates the casting and reeling process, allowing you to fish without active input, but the underlying rarity rolls use the same probabilities as manual fishing. The gamepass is purely a convenience feature priced at 49 Robux.

Can I catch Secret fish without the Ice Rod?

Yes, the base game allows any rod to hook a Secret fish provided you can reach Far Water and have enough luck for the rarity roll to succeed. However, the probability is extremely low without the Ice Rod's approximately 2.5x Fish Luck multiplier. Most confirmed Voidfish and Prism Fish catches come from players using the Ice Rod or better equipment.

What is the best rod in Pull a Lucky Fish?

As of July 2026, the Ice Rod is the best confirmed rod with an estimated 2.5x Fish Luck multiplier and a price of approximately 50 million in-game cash. The Crow Rod and Thunder Rod exist according to community reports, but their stats and acquisition methods remain unverified. Players should treat all information about rods beyond Ice Rod as speculative until Openwater Games or extensive community testing confirms the details.
