Rebirth the instant you hit the speed requirement. Not "after I get one more Secret." Not "when my base is full." Immediately. Your brainrots survive, your money stays, and the multiplier applies to everything you already own. Every minute you wait is income you're throwing away.
I wasted my first three hours "preparing" for Rebirth 1. Grinding speed, filling slots, upgrading brainrots. Then I rebirthed and realized all that grinding would have been 2x faster if I'd just rebirthed earlier. Don't make my mistake.
Rebirth Multipliers
| Rebirth | Speed Required | Total Multiplier |
|---|---|---|
| R1 | 50 | 2x |
| R2 | 75 | 3x |
| R3 | 100 | 4.5x |
| R4 | 130 | 6.75x |
| R5 | 160 | 10x |
| R6 | 200 | 15x |
| R7 | 250 | 22.5x |
| R8 | 300 | 33.75x |
| R9 | 360 | 50x |
| R10 | 430 | 75x |
The multipliers compound. R5 isn't 5x, it's 10x. R10 isn't 10x, it's 75x. A Mythic earning $3K/sec at R0 earns $225K/sec at R10. That's the same brainrot, just with rebirth multipliers.
What Rebirth Resets
Resets:
- Speed (back to base)
- Some upgrades (varies)
Keeps:
- All brainrots
- All money
- Base slots
- Fused brainrot bonuses
Your brainrots are safe. The multiplier applies to them immediately. This is why rebirthing early is always correct. You're not losing progress, you're multiplying it.
Why Waiting Is Wrong
Let's do the math.
Scenario A: You have 10 Mythics earning $30K/sec total. You wait 2 hours to "prepare" before R1.
- 2 hours × $30K/sec = $216M earned
- Then you rebirth and earn 2x
Scenario B: You rebirth immediately with the same 10 Mythics.
- Instant 2x multiplier = $60K/sec
- 2 hours × $60K/sec = $432M earned
Scenario B earns double. And that's just R1. The gap widens with each rebirth level.
The only time to delay rebirth is if you're literally 5 minutes from the speed requirement. Otherwise, rebirth now.
Optimal Rebirth Timing
R0 → R1 (50 Speed): Rush this. Buy speed upgrades, ignore everything else. Rebirth within 30-60 minutes of starting.
R1 → R2 (75 Speed): Still rushing. The 3x multiplier is huge. Should take 20-40 minutes.
R2 → R3 (100 Speed): This unlocks Secret zone. Worth a slight delay to grab a few Secrets first, but don't wait more than 10-15 minutes past the requirement.
R3 → R5 (100-160 Speed): The grind starts here. Each rebirth takes longer, but the multipliers are worth it. Rebirth immediately at each threshold.
R5 → R7 (160-250 Speed): Mid-game. You should have a base full of Secrets by now. The 22.5x multiplier at R7 is a major milestone.
R7 → R10 (250-430 Speed): Late-game grind. Each rebirth is a significant time investment, but the multipliers are massive. R10's 75x multiplier is the goal.
Speed Upgrade Priority
After each rebirth, rebuild speed in this order:
- Base speed upgrades are cheapest and most efficient
- Rebirth speed bonuses if available
- Temporary boosts during pushes to new zones
Don't waste money on other upgrades until you're close to the next rebirth threshold. Speed is the only stat that matters for progression.
Income Per Rebirth Level
How the same brainrot performs at different rebirth levels:
| Brainrot | R0 | R3 | R5 | R7 | R10 |
|---|---|---|---|---|---|
| Mythic ($3K) | $3K | $13.5K | $30K | $67.5K | $225K |
| Secret ($10K) | $10K | $45K | $100K | $225K | $750K |
| Brainrot God ($50K) | $50K | $225K | $500K | $1.1M | $3.75M |
| Divine ($300K) | $300K | $1.35M | $3M | $6.75M | $22.5M |
A Mythic at R10 earns more than a Divine at R0. Rebirth multipliers are that powerful.
Common Rebirth Mistakes
"I'll rebirth when my base is full." Your base is already generating income. Rebirthing doubles that income immediately. Fill your base faster with the multiplier.
"I need better brainrots first." Better brainrots are easier to farm with higher income. Rebirth first, then farm.
"I'm saving for a big upgrade." The rebirth multiplier IS the big upgrade. Nothing you can buy beats doubling your income.
"I'll lose my progress." You keep your brainrots and money. You only lose speed, which you'll rebuild faster with higher income.
"One more zone push." That zone push will be easier after rebirthing. The multiplier helps you afford speed upgrades faster.
Rebirth Checklist
Before rebirthing:
- Hit the speed requirement
- Spend excess money on permanent upgrades
- Check for any one-time purchases you'll lose
- Rebirth
That's it. Don't overthink it. The math always favors rebirthing early.
Post-Rebirth Priority
After rebirthing:
- Buy base speed upgrades
- Farm the highest zone you can reach safely
- Replace any low-tier brainrots with better ones
- Push toward next rebirth threshold
- Repeat
The loop is simple: rebirth → rebuild speed → farm → rebirth. Everything else is secondary.
R10 and Beyond
R10 (75x multiplier) is the current cap for most players. Some games add higher rebirth tiers in updates, but R10 is the goal for now.
At R10, focus shifts from rebirthing to:
- Farming OG zone for the best brainrots
- Hunting mutations during events
- Fusing duplicates for bonus income
- Maxing out base slots
A full base of Divines at R10 generates billions per second. That's the endgame.
