Last updated: May 30, 2026
S Tier — Buy Immediately
These upgrades are the foundation of your income. Buy every level as soon as you can afford it.
Juicer
Increases lemon production speed at the stand. The single most important upgrade in the game.
Stand Automator (Cash Register Automator)
Automates lemon stand production. The in-game button is called 'Cash Register Automator'. Frees you to explore, do deliveries, and find secrets.
2x Stand Cash
Doubles all stand income. Stacks with other multipliers for exponential scaling.
A Tier — High Priority
Strong upgrades that significantly boost your income after the S-tier essentials are in place.
Lemon Dash Fees & Speed
Boosts delivery income and vehicle speed. Makes the dash mini-game much more profitable.
Depot Per-Click & Multipliers
Your first major idle income source. Per-click upgrades scale well into mid-game.
Depot Manager
Automates the depot, creating a passive income loop.
B Tier — Buy When Needed
Situational upgrades. Buy them when they unlock new features or when you have spare cash.
Required Decorations
Buy specific decorations to unlock hidden upgrade buttons. Check which ones gate your next upgrades.
Alien Investor / Rebirth
Permanent % multipliers from alien investors. Powerful but expensive — buy after core upgrades.
C Tier — Optional
Mostly cosmetic or minor bonuses. Only buy when required for progression gates.
Cosmetic Fences & Signs
Visual upgrades with minimal gameplay impact. Buy only when required for decoration gates.
Upgrade Strategy Tips
Always prioritize automation (Stand Automator / Cash Register Automator, Depot Manager) — passive income compounds while you're offline.
Multiplicative upgrades (2x Cash, income multipliers) are better than additive ones at every stage.
Remember: Ascending resets your purchased upgrades. Focus on permanent multipliers (Alien, Evolution) and 'forever purchases' that persist across resets.
If progression stalls, check for decoration gates — you might be missing a hidden upgrade button.
