What rebirth is in Sell Lemons (layer 1 of 3)
Rebirth with Joe the Alien is the first reset layer — not void evolution (Purple Portal) and not ascension (Space Staircase). You trade current buildings and cash for permanent Alien Investors that boost every future run. Each investor adds +1% global cash (or +2% with Good Samaritan Badge from UFO Key). Rebirth is the engine that eventually fills the 501.2 Quadrillion investor total needed for void evolution. Most players rebirth dozens of times before ever seeing the Purple Portal.
How to unlock rebirth — Joe the Alien at $77 Sextillion
Rebirth does not exist at game start. When your total progression value reaches approximately $77 Sextillion — counting cash in your wallet plus every dollar already spent on tycoon upgrades — Joe the Alien lands at his UFO on your base. Talk to him directly or tap the Alien icon in the right-side menu. If no rebirth button appears, you have not hit the threshold yet — keep buying functional stand upgrades, not cosmetics.
- Threshold: ~$77 Sextillion total value (earned + spent combined).
- Joe stays permanently after first unlock — rebirth always available.
- Alien icon in side menu opens same rebirth screen as talking to Joe.
- No Robux required — pure progression gate.
What rebirth resets vs what it keeps
Rebirth wipes your active run but preserves everything that compounds long-term. Read the confirmation screen before clicking — rules are stable but BloxByte can patch edge cases.
- Resets: current cash, all buildings, all income tier progress within the run.
- Keeps: Alien Investor count and % bonus, investor-bought powers (Manage, Expert Picker, etc.).
- Keeps: Robux powers, Sewer Gate / Cosmic Cash Vine, Good Samaritan 2% rate, Forever Purchase locks.
- Keeps: void evolution ×42 stacks and fruit tier (rebirth does NOT wipe void progress).
How many investors each rebirth pays
Investor payout scales with how much wealth you built before resetting — richer runs pay more investors. There is no fixed number. Maximize payout by pushing LemonDash fees, clearing Depot decoration gates, and harvesting Cosmic Cash Vine before rebirth when the 4-hour timer is ready. Early rebirths might grant single-digit investors; midgame rebirths grant thousands. The investor guide covers spending order after each payout.
1% vs +2% rate — see investor-guide
Base +1% per investor; Good Samaritan Badge (UFO Key) permanently doubles to +2%. Full math and power spending order: investor-guide. After first rebirth, get UFO Key before grinding past ~20 rebirths at base rate.
When to rebirth — green lights and red flags
Rebirth when grinding the next upgrade takes longer than rebuilding from your current investor multiplier would take. Practical signals:
- Green: next stand upgrade takes 5–10+ minutes — rebirth now.
- Green: LemonDash fees maxed, Depot gates cleared, Manage already owned.
- Green: Cosmic Cash Vine ready to harvest before reset (bonus burst).
- Red: have not bought Manage (100 investors) yet — first rebirth buys it, second rebirth loops.
- Red: still buying stand upgrades under 2 minutes each — keep pushing.
- Red: about to void evolve at 100% — finish evolve first, then rebirth loop on new stack.
First rebirth walkthrough — minutes 0–30 after reset
Cash drops to starting amount. Buildings vanish. Joe the Alien remains in your yard — that confirms investors are active. Immediately open the green clipboard powers menu and buy Manage for 100 investors if not already owned. Rebuild Juicer → automator → LemonDash YES text. Income should climb faster than your pre-rebirth run at the same cash level — that speed difference is the investor multiplier working.
Rebirth vs void evolution vs ascension
These three systems are often confused because guides use overlapping names. In Sell Lemons specifically:
- Rebirth (Joe the Alien) — frequent, ~$77S unlock, earns Alien Investors. Powers survive.
- Void evolution (Purple Portal) — regular, 501.2Q total investors, +42× speed stacks. Resets investors and powers.
- Ascension (Space Staircase) — rare, The End 320 Octogintillion, +7.77× cash. Wipes void progress too.
- You rebirth many times before void portal opens — rebirth is not 'after' evolution.
After rebirth — investor spending
Buy Manage (100 investors) immediately if not owned. Next power tiers and 501.2Q void portal grind: investor-guide. This page stops at the rebirth button — spending order lives there.
Investor powers and rebirth — what survives
Investor-bought powers (Manage, Expert Picker, Run Faster, Stack Upgrade, Remote Buy) survive rebirth — you do not rebuy them after every reset. They reset only on void evolution and ascension. This makes rebirth cheap: rebuild buildings, keep powers, bank more investors. Speed Up Time and Forever Purchase (Robux) also survive everything.
Free Rebirth Pass — why most guides say skip
Roblox sells a Free Rebirth Pass (~90 Robux) that skips the rebuild. Community consensus: skip it early. Rebuilds take minutes once Manage and investor stack are active — especially with Depot Manager automation. Save Robux for 2× Stand Cash gamepass or Speed Up Time instead. The pass matters only at extreme ascension counts where rebuilds take hours.
Rebirth mistakes that waste time
Four patterns that slow the path to void portal and ascension.
- Grinding 100+ rebirths at 1% before UFO Key — permanent efficiency loss.
- Rebirthing with zero investors spent on powers — income stays slow.
- Rebirthing right before void evolve at 100% without claiming vine harvest.
- Confusing rebirth with void evolution — different buttons, different rewards.
How to confirm rebirth worked
After reset: cash at starting value, buildings gone, Joe the Alien visible in yard, investor count higher in rebirth menu, and income at the same cash level climbs faster than before your first rebirth. Open the Alien icon to verify investor total increased. If income feels the same, you may not have had enough run wealth before resetting — push longer next run before rebirthing.
