Grow a Brainrot First Hour Gameplay Guide: Beginner Tips & Walkthrough

Your First Hour in Grow a Brainrot 🎮

This guide walks you through a real first-hour gameplay session in Grow a Brainrot, complete with tips to avoid common mistakes and maximize your early earnings!

The First Roll: Getting Your Starter Brainrot

When you enter the game, your first task is to roll for a brainrot. Here's what you need to know:

Rolling Strategy for Beginners

  • Click the Roll button to see 3 random brainrots
  • Look for affordable options - early game cash is limited
  • Don't worry about rarity yet - focus on any brainrot you can buy
  • Beginner Tip: Your first brainrot doesn't need to be rare. A cheap Common or Uncommon is perfect to start earning money!

    Making Your First Purchase

  • Walk up to the brainrot you want
  • Press E to buy it
  • The cost varies based on rarity (Common = cheaper, Rare = expensive)
  • Step 2: Planting & Starting Earnings

    After your first purchase:

  • Go to your base - Return to your designated area
  • Select the brainrot - Use number keys (1, 2, 3) for quick selection
  • Place it strategically - Don't put expensive brainrots near the door!
  • - Thieves can easily steal from slot positions close to your gate - Place valuable brainrots deeper in your base

    First Money Collection

    Stand on the money button in your base to collect your earnings. Even this first brainrot will generate cash per second!

    Important: Collect regularly - this funds future purchases and upgrades.

    Step 3: The Critical First Defensive Action - LOCK YOUR BASE! 🔒

    This is the most important step beginners forget:

    Why Locking Matters

  • Other players can walk into an unlocked base
  • They can steal ANY brainrot you have
  • You lose those brainrots permanently
  • How to Lock for Free

  • Stand on the red button near your gate
  • Your base is locked for 1 minute (completely FREE)
  • Repeat this every minute or upgrade to 24-hour lock (49 Robux)
  • Common Beginner Mistake: Forgetting to lock your base! Always lock before:

  • Going AFK
  • Exploring other areas
  • Fighting other players
  • Step 4: Building Your Second Brainrot + First Upgrade

    Once you have enough cash:

    Getting a Second Brainrot

    Roll again and purchase another one. Diversification helps:
  • If one gets stolen, you still earn money
  • Different rarities have different earning rates
  • More brainrots = more total income
  • Upgrading Your First Brainrot (Advanced)

    You can upgrade individual brainrots to boost their earnings:
  • Find the brainrot in your base
  • Interact with it to see upgrade costs
  • Each upgrade increases $/second significantly
  • Early Game Tip: Prioritize buying more brainrots over upgrading initially. More sources of income > higher individual earnings early on.

    Understanding the Evolution System 📊

    As time passes, your brainrots automatically evolve:

    StageAppearanceEarningsTime*

    👶 BabySmall & cute1x earningsStart
    🧒 TeenGrowing~1.5x earningsSeveral hours
    🧑 AdultFull size~2x earningsMore hours
    👹 MonsterMutated~3x earningsMany hours
    💀 DeadFinal form~5x earningsVery long

    *Times vary based on brainrot type; check your specific brainrot!

    Why It Matters: A brainrot in Dead form earns 5x more than the same one as Baby! Keep them for the long term.

  • Rarity differences
  • Tip: Use this to track what you have and what to aim for next!

    PvP in First Hour: Should You Attack Other Bases?

    When You Encounter Other Players' Bases

    You'll see locked or unlocked bases from other players. You can:
  • Attack an unlocked base - Try to steal their brainrots
  • Attack a locked base - Spend 49 Robux to unlock and raid
  • First Hour PvP Reality Check

  • Most new players have very few/weak brainrots
  • Spending Robux to raid usually isn't worth it early game
  • Focus on your own base instead
  • Beginner Strategy: Don't spend Robux on raids in your first hour. Build your own base stronger first!

    Common Beginner Mistakes to Avoid ❌

  • Not locking your base - Results in total loss of brainrots
  • Placing expensive brainrots near the door - Makes them easy targets
  • Spending all cash on one brainrot - Better to diversify
  • Upgrading before you have multiple brainrots - Spread income sources first
  • Going AFK without locking - Even 5 minutes of no lock = potential loss
  • Wasting Robux on locks early - Free 1-minute locks are sufficient at first
  • Ignoring the brainrot index - You might miss collection opportunities
  • Game Bugs & Edge Cases You Might Encounter 🐛

    Getting Stuck in Terrain

  • Sometimes you can fall through the floor or get stuck in a brainrot
  • Solution: Wait for a respawn option or reset the game
  • Brainrot Not Responding to Upgrades

  • If a brainrot won't upgrade despite having enough cash
  • Solution: Try clicking it again, or place a different one nearby
  • Money Collection Lag

  • Large numbers sometimes display oddly on screen
  • Solution: The money is still calculating correctly in backend
  • Pro Tip: These bugs are rare and usually temporary. Report them in the official Discord!

    Your First Hour Summary Checklist

    Roll for and buy your first brainrot (Common/Uncommon is fine)
    Place it in your base (away from the door!)
    Lock your base (use the free red button)
    Collect your first earnings
    Roll again and buy a second brainrot
    Set a reminder to lock regularly
    Explore the brainrot index
