How to Unlock Evolutions in Sell Lemons
Evolution is the core meta-progression system in Sell Lemons that transforms your fruit through increasingly powerful stages. It sits alongside Rebirth and Ascend as one of the three pillars of late-game advancement.
Each Evolution resets your Powers and Investor count. In exchange, you receive a permanent 42x income speed multiplier that stacks with every tier. This compounding effect makes Evolution the single most impactful mechanic for players pushing into the endgame.
Without Evolution, your income growth stalls once Rebirth bonuses stop scaling. With it, previously unreachable milestones become achievable within hours instead of days. Think of Evolution as the engine that transitions you from a Rebirth-focused player into a true late-game powerhouse.
Where Is the Void Portal in Sell Lemons
The Void Portal is located directly beside LemonDash and Lemon Depot, tucked right behind Joe the Alien. This is not a hidden location once you know where to look, but many players walk past it dozens of times without realizing what it does. The portal does not appear until you have met the investor requirement, so do not panic if you cannot see it yet.
Once you cross the 501.2 Quadrillion Investors threshold, the portal materializes at that exact spot. You can then approach it to begin the Evolution unlock process. The key landmarks are LemonDash on your left, Lemon Depot on your right, and Joe the Alien just behind them.
The portal itself is a large, glowing structure with a distinct purple and cyan energy signature. It is impossible to miss once it spawns. For a more detailed breakdown of the portal mechanics and surrounding landmarks, check out our guide on how to unlock the Void Evolution Portal.
Requirements to Unlock Evolution in Sell Lemons
The base requirement to unlock your first Evolution is 501.2 Quadrillion Investors. This is an enormous number that will feel out of reach at first, but Rebirth is designed to get you there. Each Rebirth generates Investors automatically, and the rate scales as you progress.
Your Investor Bonus plays a critical role in reaching this milestone. When your Investor Bonus hits 200 percent, you are in the ideal position to evolve. Waiting for this threshold means you start each new cycle from a much stronger baseline. The UFO Key helps by doubling your Investor Bonus, which can shave significant time off your grind.
Rebirth is the primary system that generates Investors. Each time you Rebirth, your income resets but you gain Investors that provide a permanent percentage boost. These Investors compound across multiple cycles, which is how you eventually reach the sextillion range. Focus on maximizing your income per second before each Rebirth to generate the maximum number of Investors possible.
The Complete Fruit Evolution Chain (E0 to E9)
Evolution progresses through ten distinct fruit stages, starting at E0 with your humble Lemon and ending at E9 with the legendary Purity fruit. Each stage represents a major milestone and comes with escalating investor requirements.
Lemon (E0) — Your starting fruit. No investor requirement since this is where everyone begins. The 42x multiplier is inactive at this stage.
Orange (E1) — The first evolution tier. Requires 501.2 Quadrillion Investors to unlock. After completing E1, you gain your first 42x income speed multiplier. This is the most significant single upgrade in the entire fruit chain.
Lime (E2) — Second tier. Requires roughly 1.5 Sextillion Investors. Your second 42x multiplier kicks in, stacking multiplicatively with the first. You now have two active multipliers working together.
Grape (E3) — Third tier. Investor requirements climb steeply from this point onward. Three stacked 42x multipliers give you a 42-cubed income boost. Players who reach Grape have mastered both Rebirth and basic Evolution cycles.
Strawberry (E4) — Fourth tier. The Evolution cycle becomes familiar by now: reset, rebuild, evolve again. Each cycle takes longer but the multiplier rewards grow exponentially.
Watermelon (E5) — Fifth tier. Five stacked 42x multipliers put your income on a completely different scale. The visual feedback from your income counter jumping with each Evolution is deeply satisfying.
Voidlemon (E6) — Sixth tier. The game introduces the Remote Buy feature here. Our Remote Buy Sell Lemons Guide covers this feature in detail. The Voidlemon stage marks a significant power spike.
Mystic (E7) — Seventh tier. Seven stacked 42x multipliers mean your income has been multiplied by 42 to the power of seven. Only the most dedicated players reach this stage.
Crystal (E8) — Eighth tier. The second-to-last evolution. Fewer than 10,000 players worldwide have reached this level, according to community discussions.
Purity (E9) — The final and rarest evolution stage. Community data suggests only around 1,971 players have ever reached Purity, making it one of the most prestigious achievements in Sell Lemons.
How to Reach the Void Altar in Sell Lemons
Entering the Void Portal is only half the battle. Once you step through, you need to complete a parkour sequence across floating rocks to reach the Void Altar at the center of the Void space. This is where most guides fall short and where many players get stuck.
Step 1: Approach the Void Portal beside LemonDash and Lemon Depot, behind Joe the Alien. Confirm you have the 501.2 Quadrillion Investors requirement. Press the interact button when the prompt appears.
Step 2: You will be transported into the Void. Pause to orient yourself. Look for the series of floating rocks forming a visible path toward the center. These rocks are spaced at jumpable distances but require precise timing.
Step 3: Jump from rock to rock, moving steadily inward. Do not rush. Missing a jump means falling back to the starting platform and beginning again. Watch your landing carefully and adjust your approach as needed.
Step 4: The final rock leads directly to the Void Altar. Approach it and press the interact button. This triggers the Evolution cutscene and completes your first evolution.
The parkour gets easier with practice. I recommend taking it slow on your initial attempt. Get a feel for the jump distances and camera angle inside the Void. Once you find the rhythm, you will reach the Void Altar in under thirty seconds consistently. Many players on r/Roonby confirm that practice makes perfect for this sequence.
What Happens When You Evolve in Sell Lemons
When you interact with the Void Altar and complete an Evolution, two major resets occur. Your Powers reset to their base values. Any power upgrades you purchased are removed, so you will need to rebuild them from scratch. Your Investor count also resets to zero.
All the investors you built up since your last evolution disappear. This feels punishing by design. Evolution is a meta-progression reset, similar to Rebirth but at a higher tier with bigger rewards. The key difference is what carries over.
Each Evolution permanently adds another 42x income speed multiplier to your total. After E2, you have two stacked multipliers. After E3, three stacked multipliers. Rebirth gives a linear boost through Investors, but Evolution multiplies that boost exponentially. This is why experienced players call Evolution the true endgame progression system.
When Should You Evolve in Sell Lemons
The best time to evolve is when your Investor Bonus reaches 200 percent. At this threshold, your income generation runs at peak efficiency for your current stage. Evolving below 200 percent means starting your next cycle from a weaker position.
The difference between evolving at 150 percent and 200 percent can be significant. The UFO Key doubles your Investor Bonus, helping you hit that 200 percent threshold faster. Some players also use the Forever Purchase power to lock in progress before evolving.
The key principle is to always evolve from maximum strength, not desperation. If you are unsure whether you are ready, wait one more Rebirth cycle and reassess. Patience almost always pays off in Sell Lemons, and rushing an Evolution at the wrong time can cost you hours of grinding later.
Evolution vs Ascend in Sell Lemons
Evolution and Ascend serve different purposes in the late-game. Evolution focuses on income speed through the 42x multiplier chain. Ascend operates at a higher tier, resetting more progress but granting permanent bonuses that affect all future runs.
The community strategy is to prioritize Evolution first. The 42x multiplier benefits every Ascend cycle you run afterward, creating a compounding advantage. Once you have several Evolution stages, switch to Ascend for permanent boosts, then return to Evolution with your enhanced baseline.
Think of Evolution as your income engine and Ascend as your permanent stat layer. They work best in sequence rather than against each other. Start with Evolution, reach three or four tiers, then evaluate how Ascend fits into your overall strategy.
Evolution Milestones and Late-Game Strategy
Tracking progress through the Evolution chain helps you set realistic goals. Early evolutions from E0 to E2 are achievable within a few Rebirth cycles. E3 to E5 requires serious time investment and efficient income optimization.
Stages E6 through E9 are where the real grind begins. The Voidlemon stage at E6 unlocks Remote Buy, which changes how you manage income. Late-game players should consider the interaction between Forever Purchase and Evolution. Forever Purchase buys permanent upgrades that do not reset during Evolution, preserving bonuses through the reset cycle.
Combining Forever Purchase with the UFO Key creates a powerful synergy that reduces time between evolutions. The r/Roonby community has found that players who invest in both systems early find the late-game far more manageable. Set goals based on the fruit chain rather than raw numbers for better motivation.

Where is the Void Portal in Sell Lemons?
The Void Portal is located beside LemonDash and Lemon Depot, directly behind Joe the Alien. It only becomes visible and interactable once you have accumulated 501.2 Quadrillion Investors. Walk to that area after a Rebirth run and look for the glowing portal structure.
What does evolving do in Sell Lemons?
Evolving resets your Powers and Investor count but grants a permanent 42x income speed multiplier that stacks with each Evolution tier. This compounding multiplier is the main benefit of Evolution and becomes increasingly powerful as you progress through the E0 to E9 fruit chain.
When should I evolve in Sell Lemons?
The best time to evolve is when your Investor Bonus reaches 200 percent. Waiting for this threshold ensures you start each new evolution cycle from maximum efficiency. The UFO Key helps accelerate this by doubling your Investor Bonus, letting you evolve sooner without sacrificing your starting position.
Unlocking Evolutions in Sell Lemons is one of the most satisfying achievements in the game. It requires patience, strategic timing, and the willingness to push through a few reset cycles. But the payoff is enormous. Every Evolution you complete adds another 42x multiplier to your income, and those multipliers compound fast. By the time you reach the Purity fruit at E9, you will be earning at a rate that would have seemed impossible during your early Rebirth runs.
The Void Portal beside LemonDash and Lemon Depot, the parkour to the Void Altar, and the investor threshold of 501.2 Quadrillion are all manageable with the right preparation. Wait for your Investor Bonus to hit 200 percent, use your UFO Key wisely, and do not rush through the evolution stages. Set milestone goals based on the fruit chain rather than raw numbers to stay motivated. For more Sell Lemons strategies and guides, visit our Sell Lemons game hub. Happy evolving.
