Search intent
Players search sell lemons buildings or income sources and need unlock order plus the Depot hidden-button problem.
How the 8 income tiers stack
Higher tiers multiply lower tiers — never ignore Lemon Stand and LemonDash in endgame. Republic and LemonX bonuses apply to your entire income stack below them.
- Tiers 1–3: Stand, LemonDash, Lemon Depot (early–mid)
- Tiers 4–7: Trading, Labs, Republic, Robotics (hill)
- Tier 8: LemonX (space / endgame)
1. Lemon Stand
Your $1 starting loop. Priority upgrades: Juicer, Cup Stand, Sugar Mixer. Hire Lily Gumdrop (Stand Automator) first — removes manual clicking.
2. LemonDash
Delivery income from phone unlock. Reply YES to the first text for an ~$83,000 bonus. Upgrade delivery fees and vehicle speed before cosmetic motorbike skins. Hire the LemonDash Manager after fees are strong — see the lemon-dash guide for the full YES text walkthrough.
3. Lemon Depot — decoration gate system
The Depot is the #1 midgame trap: many upgrade buttons are hidden until you buy specific decorations. After every decoration purchase, walk through the entire factory — players plateau thinking they maxed out when buttons are still concealed. See the dedicated lemon depot guide for the full roof/walls/lights checklist.
- Buy Depot roof — reveals major hidden upgrade rows.
- Buy walls and lights — more buttons appear.
- Max per-click cash and depot multipliers before the Depot Manager.
- Unlock cost is around billions — save after LemonDash spikes.
4–7. Hill income (Trading, Labs, Robotics, Republic)
Mid–late game skyscraper floors. Each adds multipliers to the full stack below. Hire managers only after that tier's core upgrades are purchased — managers automate, they do not fix weak bases. See lemon-trading for tier-4 deal timing.
8. LemonX
Endgame space-station income. Pairs with Ascension and void evolution planning. Neglecting lower tiers still wastes money because LemonX multiplies everything beneath it.
Income tier unlock order
| Tier | Source | Phase | Manager priority |
|---|---|---|---|
| 1 | Lemon Stand | Start | Lily Gumdrop — highest early |
| 2 | LemonDash | Early mid | After max delivery fees |
| 3 | Lemon Depot | Mid | After depot multipliers + decorations |
| 4 | Lemon Trading | Mid–late | After understanding market timing |
| 5 | Lemon Labs | Late mid | When lab upgrades are active |
| 6 | Lemon Robotics | Late | After robotics upgrades maxed |
| 7 | Lemon Republic | Late | Endgame stack multiplier |
| 8 | LemonX | Endgame | Post-Ascension scaling |

Why are my Lemon Depot upgrades missing?
Decoration gates hide buttons. Buy roof, walls, and lights, then walk the factory to find newly revealed upgrades.
When should I hire managers?
Stand Automator first, LemonDash Manager after fees are maxed, Depot Manager after depot multipliers — never hire before the tier earns enough to justify cost.
