Rebirth & Progression Guide
Rebirth is the most powerful progression mechanic in Be a Lucky Block. Resetting at the right time with the right setup is the difference between slow mid-game crawl and rapid late-game acceleration.
What Is Rebirth?
Rebirth is a voluntary progression reset available once you meet specific requirements (typically a minimum cash balance or Brainrot tier). When you Rebirth:
- ❌Your current Cash balance resets to 0
- ❌Your collected Brainrots are cleared from your base
- ✅You gain a permanent Cash multiplier applied to all future income
- ✅You unlock additional base slots for more Brainrots
- ✅Future farming runs are faster and more efficient
Key insight: The permanent multiplier makes every subsequent rebirth faster than the last. Rebirth 5 at 5x multiplier means you recover your base income 5× faster than Run 1 — making early sacrifices worthwhile.
Rebirth Milestones & Timing
Rebirth 1
First Rebirth. Do this after you have a Diamond Pickaxe and a full base of Epic Brainrots.
Rebirth 2
Second Rebirth. Aim for Rainbow or Beanstalk Pickaxe before resetting.
Rebirth 3
You can now access Legendary Blocks more efficiently after resetting.
Rebirth 5
Key milestone. Post-Rebirth 5, your income growth accelerates dramatically.
Rebirth 10
Late-game rebirths are faster thanks to stacked multipliers. Focus on God-tier farming.
⚗️ Fuse Machine
The Fuse Machine lets you combine two identical Brainrots into a single higher-rarity version. This is critical before a Rebirth — fuse your best Brainrots so you can place them immediately after resetting, recovering income much faster.
Select two identical Brainrots
Both must be the same unit and rarity.
Fuse to combine them
Result is a promoted version of the original.
Save before Rebirth
Fused Brainrots are retained in a special slot across resets.
✨ Mutation System
Mutations apply special multipliers to individual Brainrots, significantly increasing their cash-per-second output. Types of mutations include:
Gold Mutation
1.5× income multiplier on the target Brainrot.
Diamond Mutation
2× income multiplier. One of the most common mid-game targets.
Rainbow Mutation
3× income multiplier. Rare but game-changing for high-tier units.
Electro Mutation
4× income multiplier. Late-game exclusive mutation.
Mutations stack with base income, making them especially powerful on God-tier Brainrots. A God-tier unit with a Rainbow Mutation can earn 3× the base 10,000+ cash/sec.
