Cut Grass for Brainrots is a fun Roblox tycoon/simulator where you swing a weapon to mow thick grass, uncover hidden Brainrots (cute but chaotic units), and collect them for passive income. Upgrade your damage to cut faster, unlock new zones, and Rebirth for massive permanent power-ups.
Rebirth is the core endgame system that turns slow early-game grinding into insane exponential progress. Players routinely hit 20+ rebirths in hours once optimized. Here’s everything you need for max rebirths.
What Is the Rebirth System?
Rebirth resets your current run (damage and temporary progress) but gives permanent stacking bonuses that make every new run 5x–10x+ faster.
- Key Benefits:
- Permanent cash/money multiplier (stacks exponentially with each rebirth)
- Bigger attack radius (your cutter swings in a huge area — super important for clearing grass fast and reaching new zones)
- Faster overall progression (damage builds quicker due to multipliers)
- What You Keep:
- All Brainrots (your pets/units)
- Mutations on Brainrots
- Any permanent upgrades
- What Resets:
- Current damage level
- Temporary money and progress in the run
No hard cap on rebirths — you can keep going forever. “Max Rebirth” usually means pushing to 20–50+ (or as high as your multipliers allow) for god-tier farming speed.
How to Rebirth (Step-by-Step)
- Grind damage by upgrading your cutter and collecting Brainrots.
- Hit the current damage threshold (starts at ~1,000 damage for your first rebirth).
- Open the menu → Find the Rebirth button → Confirm.
- Boom — instant permanent multipliers + bigger radius!
Early-game requirement: ~1,000 damage. Later rebirths: Threshold scales up (cash + damage milestones), but your stacked multipliers make it way easier each time.
Pro Tip: Rebirth the moment you hit the threshold. Don’t over-farm — the permanent bonuses pay off immediately.
Strategy for Max Rebirths (Beginner → Endgame)
Phase 1: First Rebirth (Noob Setup)
- Start by buying basic damage upgrades.
- Collect any Brainrots you find — even weak ones give income.
- Focus purely on damage until you hit 1,000.
- Rebirth #1 → Get your first cash multiplier + radius boost.
Phase 2: Fast Rebirth Grinding (Mid-Game)
- Use your new radius to clear huge grass patches quickly.
- Prioritize strong Brainrots for income (they stack with rebirth multipliers).
- Rebirth every 5–10 minutes once thresholds become easy.
Phase 3: True Max Rebirths (Endgame)
- Stack 10–20+ rebirths → multipliers go crazy (10x+ cash, massive radius).
- You’ll mow entire maps in seconds and hit new zones instantly.
- Goal: Rebirth as often as possible — each one makes the next run 2–5x faster.
Best Practices for Speed:
- Always max damage upgrades before rebirthing.
- Equip your strongest mutated Brainrots (they give passive cash).
- Farm in high-density grass areas unlocked by bigger radius.
- Rebirth loop: Build damage → Rebirth → Repeat. This is how top players reach rebirth 20+ in under an hour.
Best Brainrots & Mutations (Boost Rebirth Speed)
Brainrots are your income engines. Mutations multiply earnings even more:
- Gold → 1.5x earning rate
- Diamond → 2.5x
- Rainbow → 4x
- Electro (best) → 6x
Hunt rare Celestial Brainrots for huge boosts. Pair them with rebirth multipliers for broken income.
