Sell Lemons Buildings Guide
All five areas in unlock order, building layout, decoration gates, and map progression from the $1 Lemon Stand through Lemon X (upgrade costs on Income Sources).
Listed in the order you unlock them, from the $1 Lemon Stand through Space Station Lemon X. Per-source cash and speed upgrade costs live on Income Sources; this page covers unlock prices, building layout, and decoration gates.

Tier 3: Lemon Depot (factory)

Project Stargate (Lemon X)
Open since September 4, 2026 (v1.4.0)
- Unlock and launch to Space Station Lemon X from the rocket pad.
- Walk past the Lemon X income zone toward the Space Center at the far end of the station.
- Enter the Stargate door that used to say Coming Soon, then clear Installation Stargate.
- Inside you will find build pads (Ascension hold costs, not spends) and the World Reactor.
- The Select World portal in that interior is the door to World 2.
- Stargate buttons ask you to hold Ascensions on the pad. They do not spend those Ascensions.
- World Reactor converts Ascension chains into World Energy for a shared Global Multiplier.
- World 2 teleports from Select World after v1.5.0 (September 18, 2026).
- Alien visitor activity nearby still ties into recurring Alien Invasion events.
| System | Detail |
|---|---|
| World Reactor | Power pad inside Stargate. Hold 3 Ascensions to buy, then Ascend again until the reactor is live on your save. |
| Energy payout | While the Energy timer is running, each qualifying Ascension pays +100 World Energy. Chain Ascends before the timer hits zero. |
| Bank cap | Energy bank caps at 30,000. Filling it pushes the Global Multiplier toward ×10 across worlds. |
| Companions | Energy milestones unlock Laser Helper (500), Purity Shard (2,500), and Exogadro (25,000). Cosmetics only. |
World 2 unlock and oxygen loop: World 2 wiki. Glorp Cat and UFO still drop during invasion windows; see Orchard and patch notes.
After Stargate opens
Opened September 4, 2026 (v1.4.0)
Stargate and World 2 are both live. Use this checklist before you hop planets:
- Walk Lemon X → Stargate and confirm World Reactor pads on your save.
- Farm Energy if you want Global Multiplier before hopping to World 2.
- Orchard Tokens and plots stay permanent; no need to dump them before World 2.
- Chase Glorp Cat or UFO during the next Alien Invasion window if you want those cosmetics.
- When you are ready for Mars, use Select World → World 2 and expect a full income reset there.
Live Stargate notes
- v1.4.0 opened the Stargate interior, World Reactor, and Energy.
- v1.5.0 World 2 shipped September 18, 2026: oxygen tycoon, Alien Researchers, Primordial Void → Breeze.
- World 1 rebirth, void, and ascension thresholds have no published change from these drops.
Next steps
- Read the World 2 wiki for oxygen stations and Researcher rebirth timing.
- Update the milestone calculator plan only for World 1 gates until World 2 ETA fields exist.
