Unofficial Sell Lemons Wiki — not affiliated with BloxByte Games or Roblox Corporation. Verify stats in-game after patches.
Sell Lemons tracks twenty-four Roblox badges across income sources, wealth milestones, systems, and hidden quests. Use this list to plan which unlocks are automatic and which need a dedicated sewer or Evolution run.
Good Samaritan (~1.8%) and Cosmic Farmer (~5%) are the mid-game sewer pair — vine work and stranger quest that permanently improve Cosmic Cash and investor math. Purity sits under 0.01% as the Evolution end badge.
Earn rates below come from Roblox badge API snapshots. Percentages drift as the player base grows; treat them as relative rarity, not exact live odds.
New players often clear Lemon Stand through Trading badges without opening a guide. The cliff starts at Lemon Labs / Robotics, then Lemon Republic, then Moon LemonX after Void Evolution — that is where earn rates fall from double digits toward under one percent.
Bookmark this page beside the Sewer, UFO Key, Evolution, and Powers guides: the tables tell you what popped, the guides tell you which button order or investor bank actually unlocks the rare rows.
Sell Lemons Hidden Badges Walkthrough
Watch this hidden-badges walkthrough first (Out of this World, Dimensional Dealmaker, We Are So Back, Purity), then use the rarity cards and full tables — including Cosmic Farmer and Good Samaritan — below.
Priority Sell Lemons Badges
Four badges that change progression math — not every 100% Lemon Stand unlock.
Good Samaritan
~1.8% earn rate. Finish UFO Key / stranger quest for 2% investor cash. Do this before mass Rebirth farming.
Cosmic Farmer
~5% earn rate. First Cosmic Cash Vine harvest after the Sewer Key unlock. Then harvest on a multi-hour timer.
Purity
<0.01%. Reach Purity fruit (E9). Pair with the Evolution guide investor thresholds.
Powered Up → Ultimate
First power is common (~24%). All seven powers is near-mythic — bank investors wisely.
Badge Hunting Tips Board
Sewer badges first
Cosmic Farmer then Good Samaritan. Mixing vine and UFO lever projects in one session soft-locks many players.
Out of this World
First Alien Investor via Joe Rebirth (~25%). Required before the UFO Key even spawns.
Cash badges auto-pop
Millionaire through Centillionaire track balance peaks. Ascend/Rebirth loops will collect most of them passively.
Dimensional Dealmaker
~3.2%. Accept the Void’s offer during Evolution — read altar prompts carefully.
We Are So Back
~0.1%. Tied to completing late staircase Ascension at the end of the expanded base.

How to Read This Sell Lemons Badge List
Income-source badges pop when you buy each major building line from Lemon Stand through LemonX. Wealth badges track peak cash — Ascend resets buildings but your lifetime high still progresses those milestones as you climb notation.
System badges cover powers and Alien Investors. Roblox also flags several progression badges as hidden: Out of this World (first investor), Dimensional Dealmaker (Void offer), We Are So Back (staircase Ascension), and Purity (E9). Separately, Cosmic Farmer and Good Samaritan are the sewer mid-game pair — vine harvest and stranger quest — covered in the Sewer and UFO Key guides.
If you only chase one mid-game pair, clear Cosmic Farmer then Good Samaritan before heavy Rebirth farming. That order protects Cosmic Cash income and doubles every future Alien Investor's cash bonus.
Wealth badges from Millionaire to Centillionaire are mostly automatic if you keep Ascending and Rebirthing — Centillionaire is the prestige flex under 0.01%. Powered Up arrives with your first green-board power; Ultimate Power waits until all seven Sell Lemons powers are owned.
