Game Mechanics & Zones

Understanding the mechanics of My Fishing Brainrots. Master the zones, optimize your luck, and enchant your gear.

🎮 Core Game Systems

Master these 5 interconnected systems to optimize your fishing empire and reach Rebirth 9.

🎰

System 1: Conveyor Belt (Gacha Engine)

The physical egg spawning and hatching system

How It Works

  • Physical Spawning: Eggs spawn on a moving belt in the 3D world. You can SEE them before purchase.
  • Purchase Price: $500 → $50,000+ based on your Rebirth tier. Scales exponentially.
  • Anticipation Window: Watch the belt for visual cues (glow, size) before committing cash.
  • Sniping Strategy: Experienced players wait for "good feeling" eggs instead of buying blindly.

Upgradeable Stats

⏱️ Conveyor Speed

Increases egg spawn rate. Max level = ~1 egg every 2-3 seconds. More chances = more pulls per minute.

🍀 Conveyor Luck

Increases rarity of units in eggs. CRITICAL for hatching Legendary gatekeepers (Chef Crab Kadabra needs Luck 3+).

💡
Pro Tip: Use the LUCKY code (2x Luck for 10 mins) when you have $500K+ saved. Buy 50-100 eggs during the buff window for maximum efficiency.
🤖

System 2: Fishing Automation Engine

How your brainrots generate passive income

Core Mechanics

  • Units as Workers: Each brainrot unit places on your "island" base and automatically fishes.
  • Base Slots: Start with 10 slots. Upgradeable to 50+ for endgame. More slots = more workers.
  • Rod as Multiplier: Your fishing rod provides a % bonus to ALL units' output (10% → 500%+ at max).
  • Physical Growth: Units VISUALLY grow larger as they level up (~25x size at Lv 50).
  • Income Formula: Total $ = Σ(Unit Base EPF × Unit Level × Rod Bonus × Buff %).

Optimization Strategy

  1. Early Game: Fill all slots with ANY units. 10 Commons > 3 Rares.
  2. Mid Game: Replace weakest Commons with Legendaries as you hatch them.
  3. Late Game: Full team of Lv 50 Mythicals/Forgottens. One Avocado Owl Lv1 > 10 Commons Lv50.
  4. Buff Placement: Place Fruity Frera (15% buff) in CENTER of your best unit cluster.
📚

System 3: Fish Index Collection System

Permanent global cash bonuses through discovery

How It Works

  • Discovery Mechanic: First time you catch each brainrot, it's added to your "Fish Index" encyclopedia.
  • Section Completion: Index is divided into sections (Common, Rare, Legendary, etc.).
  • Bonus Per Section: Complete a full section = +5% global cash bonus (permanent, stacks across rebirths).
  • Max Bonus: With 10+ sections, you can get +50-70% total cash from Index alone.
⚠️
Important: Fish Index bonuses are MULTIPLICATIVE with Rod and Buff bonuses. A 50% Index bonus on a 400% Rod = 6x total multiplier, not 4.5x. This makes Index completion critical for late-game scaling.
🔄

System 4: Rebirth System (Vertical Progression)

Reset for permanent multipliers and new floors

How Rebirths Work

  • Requirements: Each Rebirth needs (1) a specific cash amount AND (2) a specific gatekeeper brainrot unit.
  • What You Lose: ALL cash + non-permanent upgrades are reset to zero.
  • What You Keep: Fish Index bonuses, Gatekeeper units, permanent upgrades purchased with Tokens.
  • What You Gain: Permanent cash multiplier (2x → 5x per rebirth) + unlock new vertical floor.
  • Floor Benefits: New floors have more base slots and higher egg tier spawns on Conveyor Belt.

Rebirth Requirements Table

Rebirth Cash Required Gatekeeper Unit Multiplier Gained
Rebirth 1 $100,000 Salamino Penguino 2x
Rebirth 2 $500,000 Orangutini and Aidi 2.5x
Rebirth 3 $2,000,000 Chef Crab Kadabra 3x
Rebirth 4 $10,000,000 Bona and Balaboo 3.5x
Rebirth 5 $50,000,000 Globo Watermano 4x
Rebirth 6+ $200M+ Quid 4.5x
Rebirth 9 $50 TRILLION L Grande + Matteo 5x+
🎯
Strategy: Don't rebirth the moment you can. Farm extra cash FIRST to upgrade Conveyor Luck + Rod before rebirthing. This makes the next rebirth cycle faster because you'll hatch better units immediately post-reset.
📈

System 5: Level Scaling & Growth

How units become exponentially more powerful

Core Mechanics

  • Leveling: Units gain EXP from fishing. Cash pays to level them up manually (faster than waiting).
  • Power Scaling: By Level 50, a unit has ~25x its base EPF value. A $100 Common becomes $2,500 at max level.
  • Visual Growth: Units physically grow in size. A Lv 1 unit is 0.5x player height. Lv 50 = 3-4x player height.
  • Social Signal: Large units on your island = "wealth flex" to visiting players.

Post-50: Rank Up System

What is "Rank Up"?

At Lv 50+, you can "Rank Up" a unit. This RESETS their level to 1 but grants Tokens (premium currency).

Token Uses

Tokens buy permanent account buffs (Cash %, Rod %, Conveyor Speed) that NEVER reset, even through rebirths.

Scaling Example: Gold Radioactive Tornado Swag
Level EPF Value Multiplier
Lv 1 $48.75 Million 1x
Lv 25 ~$600 Million ~12x
Lv 50 $1.24 Billion 25.4x

This scaling is WHY a single Forgotten tier unit beats an entire team of Commons, even if the Commons are maxed.

💡 How the Systems Work Together

The Optimal Gameplay Loop

  1. Buy eggs from Conveyor Belt → Use Conveyor Speed/Luck upgrades for efficiency
  2. Hatch units & fill base slots → Higher rarity = better base EPF
  3. Level units to 50 → 25x power multiplier from scaling
  4. Complete Fish Index sections → +5% global bonus per section (multiplicative!)
  5. Farm cash for Rebirth requirements → Need both $ AND gatekeeper unit
  6. Rebirth when ready → Permanent multiplier + new floor + better eggs
  7. Repeat 1-6 until Rebirth 9 → Final goal = $50T Matteo purchase
