Droid Cities

frequently asked questions

How do I create an account?
Click on the Register link and provide your email address and a password. The system will automatically assign you a unique username in the format Droid_XXXXX.
What resources do I start with?
New players start with:

Buildings: Level 1 Base, Level 1 Factory, Level 1 Refinery, Level 1 Forge, and Level 1 Security Station.
Droids: One Level 1 Harvester droid.
Resources: 1,000 BC (BitCredits), 100 Oil, and 100 Iron.
How do I gather resources?
Assign your Harvester droids to gather Oil and Miner droids to gather Iron. Each action is instant and consumes 1 use and 1 Oil from the droid.
When does my base produce BC?
Your base automatically produces BitCredits every hour on the hour (UTC time). The amount depends on your base level.
What happens when a droid runs out of uses?
Droids with 0 uses become deactivated and must be repaired at the Factory. Repair costs 50 Oil and 50 Iron and restores 75 uses.
How do I upgrade my base?
Go to the Building Maintenance section and select the Base card. Pay the required resources (BC, Oil, and Iron) and have the required number of builder droids available. Builder droids are consumed when used for upgrades. Upgrade requirements:

• Level 1→2: 2 builder droids
• Level 2→3: 5 builder droids
• Level 3→4: 10 builder droids
• Level 4→5: 25 builder droids

The upgrade completes instantly when initiated.
What are cards used for?
Cards are collectibles that come in different rarities. Completing a full 12-card set grants you a choice of 250 BC, 500 Oil, or 500 Iron.
How does the marketplace work?
Players can buy and sell Oil, Iron, droids, and cards. Listings last 7 days. Sellers set BC prices, and a 5% fee applies on sales. All trades complete instantly.
What are leaderboards?
Leaderboards rank players by total city value, which includes buildings, droids, resources, and cards.
Are there storage limits for resources?
No, resources have no storage limits. You can accumulate as much BC, Oil, and Iron as you want.
How do builder droids work?
Builder droids are required for all building construction and upgrades. They have no levels - any builder droid will work. However, upgrades require specific numbers of builder droids:

• Constructing a building: 1 builder droid
• Level 1→2 upgrade: 2 builder droids
• Level 2→3 upgrade: 5 builder droids
• Level 3→4 upgrade: 10 builder droids
• Level 4→5 upgrade: 25 builder droids

Builder droids are permanently consumed (expended) when used for construction or upgrades. Build more builder droids at your Factory to maintain your construction capacity.
Where do I manage my buildings?
All building management, including upgrades for Base, Factory, Refinery, and Forge, is handled in the Building Maintenance section (accessible from Quick Actions). You can view building status, upgrade requirements, and perform upgrades all from this centralized location.
