Game overview
What is Steal a Brainrot 100% Original game?
Steal a Brainrot 100% Original is the definitive version of the viral idle game that took the internet by storm. It's a chaotic blend of pet collection, idle income generation, and meme culture that hooks you with its "just one more minute" gameplay loop. Think Cookie Clicker meets PokƩmon collecting, but with cursed AI-generated creatures that will haunt your dreams (in the best way possible).
This is the original, unmodified version that started it allābefore the remakes, the clones, and the spinoffs. If you want the pure, authentic Brainrot experience, this is where you start:
- The Goal: Build the most valuable collection of Brainrot pets, climb the leaderboard, and chase the legendary Rainbow tier.
- The Loop: Collect pets, earn idle income, complete sets for massive multipliers, and Rebirth for permanent bonuses.
- The Vibe: Addictive idle mechanics + meme chaos + satisfying number-go-up dopamine hits.

Gameplay: How to play Steal a Brainrot 100% Original?
The core gameplay is beautifully simple, but mastering the progression system takes strategy. Here's how to become a Brainrot tycoon:
- Start with Your First Pet: You begin with a single Normal-tier pet. It generates passive income over timeāeven when you're not playing!
- Buy More Pets: Use your earnings to purchase additional pets. Each new pet increases your income rate. Fill your house with as many creatures as possible.
- Unlock Higher Tiers: As you earn more, you'll unlock better pet tiers: Normal ā Gold ā Diamond ā Rainbow. Higher tiers = exponentially more income.
- Complete Sets for Bonuses: Collecting all pets within a single tier activates a powerful SET BONUS multiplier. This is key to scaling your income.
- Trigger Combo Multipliers: The more pets you have active, the higher your combo multiplier grows. A full house = insane cash flow.
- Rebirth for Permanent Gains: When progress slows down (upgrades take forever), hit the Rebirth button. You'll lose your current pets and cash, BUT you gain a permanent multiplier that makes every future run faster and more profitable.
- Repeat & Optimize: Each rebirth makes you stronger. Stack multiple rebirths to reach the coveted Rainbow tier pets and dominate the leaderboards.
Pet Rarity Tiers
Understanding the rarity system is crucial for optimal progression:
| Tier | Color | Income Rate | Availability | Set Bonus |
|---|---|---|---|---|
| Normal | Gray/White | Low | Starting tier | +50% income when complete |
| Gold | Shiny Gold | Medium | Mid-game | +100% income when complete |
| Diamond | Crystal Blue | High | Late-game | +200% income when complete |
| Rainbow | Multi-colored | EXTREME | Endgame (multiple rebirths) | +500% income when complete |
Pro Tip: Don't rush to the next tier until you complete the current one's set bonus. The multiplier is more valuable than one fancy pet!
The Rebirth System
Rebirth is the core progression mechanic that separates casual players from leaderboard legends:
- When to Rebirth: If your next upgrade takes 5+ minutes of waiting, it's time. You've hit the soft cap for this run.
- What You Lose: All pets, all cash, all current progress.
- What You Keep: A permanent MULTIPLIER (usually 2x-5x) that applies to ALL future income. This stacks forever.
- The Strategy: Early rebirths should happen frequently (every 10-20 minutes). Late-game rebirths happen after hours of grinding for maximum multiplier gains.
Example: Your first run takes 30 minutes to reach 1 Million coins. After rebirth with a 3x multiplier, your second run hits 1 Million in just 10 minutes. By your 5th rebirth, you're printing Rainbow pets like candy.
Strategy & Tips
Want to maximize your gains and reach Rainbow tier faster? Follow these expert tips:
- Always Complete Sets: The set bonuses are multiplicative, not additive. A complete Normal set gives more income than a half-finished Gold set early on.
- Balance Your Spending: Don't blow all your cash on one expensive pet. Spread purchases to maintain high combo multipliers (more pets = better combos).
- Track Your ROI (Return on Investment): Before buying, mentally calculate: "Will this pet pay for itself quickly?" Early game = buy cheap pets fast. Late game = save for big purchases.
- Don't Rebirth Too Early: If you can still afford upgrades every 30-60 seconds, keep going. Squeeze more value out of each run.
- Don't Rebirth Too Late: If you're waiting 10+ minutes for a single upgrade, you're wasting time. Reset and blast through the early game with your new multiplier.
- Focus on Income Per Second (IPS): The best upgrade isn't always the coolest pet. Look at the IPS boost percentageābigger % = better buy.
- Mobile Tip: The game runs perfectly in the background. Open it periodically to collect idle earnings and make purchases, then close and let it cook.
