Quick Conclusion: Day 1 Priority: Solar Collector ×2 → Water Purifier ×1 → Residential ×1. Do not build Battery first. Lay green pathways immediately after residents move in to boost satisfaction, otherwise Day 3 will trigger resident departure due to low satisfaction.
Day 1 Build Order
| Priority | Building | Why | Time |
|---|---|---|---|
| 1 | Solar Collector ×2 | Base power generation, must be operational before night | Day 1 Morning |
| 2 | Water Purifier ×1 | Unlock water supply for new residents | Day 1 Morning |
| 3 | Residence ×1 | Attract first 4 residents | Day 1 Afternoon |
| 4 | Storage Depot | Increase resource storage capacity | Day 1 Afternoon |
| 5 | Green Path ×3 | Satisfaction buffer, prevent Day 3 departure | Day 1 Evening |
Pro Tip
Only collect Metal from south area and Parts from east area. Spreading drones too thin early game is the most common mistake.
Satisfaction System Basics
Resident satisfaction starts at 60 and decays by 3 per day. Satisfaction affects:
- Resident departure threshold (40 points)
- Population growth rate
- Resource production efficiency
- Power stability: ±0 if no blackouts, -5 per blackout
- Green coverage: +2 per tile within residential range (max +10)
- Water supply: +3 if purifier operational
- Noise pollution: Industrial zones within 4 tiles of residential lose -2 per tile distance
Residents depart when satisfaction drops below 40. Without green paths, stable power, and proper industrial zoning, satisfaction will easily breach the red line by Day 3.
Common Starting Mistakes
| Death Cause | Time | How to Avoid |
|---|---|---|
| Metal depletion, cannot build critical structures | Day 1-2 | Do not build Battery first; focus drones on south Metal |
| Satisfaction below 40, residents depart | Day 3 | Lay at least 3 green path tiles covering residential before Day 3 |
| Power deficit, buildings shut down | Day 2-3 | Second Solar Collector must be built before Day 1 afternoon |
| Water shortage, new residents cannot move in | Day 2 | Water Purifier priority second only to first Solar |
Recommended Play
If you want to minimize thinking, just follow the table order. Drones only collect south Metal and east Parts, lay green on Day 3. This opening can stably transition to mid-game.
