Overview
Orange X (badge name: LemonX / Interstellar Lemons) is the 8th and final income source in Sell Lemons, and the rarest — only 0.3% of players have earned this badge. Accessible only after Void Evolution transforms your lemons into oranges, Orange X takes your operations to the Moon via rocket construction. This represents the absolute pinnacle of income in Sell Lemons, available only to the most dedicated players who have mastered every system.
How It Works
Orange X introduces a completely new dimension to the game:
Build a rocket to launch to the Moon. This requires significant resources accumulated through Void Evolution progression.
Establish a Moon base for interstellar lemon trading operations — the highest-tier income in the game.
Trade lemons (now oranges) at interstellar prices. Sell values are orders of magnitude higher than any Earth-based income source.
Orange X income scales with Evolution level and Ascend multipliers — the compound effect is astronomical.

Strategy
Balance Orange X investment with Ascend cycling. Don't stop Ascending — the compound multiplier effect is what makes Orange X truly powerful.
Void Evolution must be well-progressed before Orange X becomes accessible. Evolution 60+ is recommended before attempting the rocket.
Don't rush Orange X. It's the ultimate endgame goal — focus on mastering all prior systems first.
