How do I get Gold?

Buy it in the Gold Shop or ask the server owner.

Why can't I finish some buildings with Gold?

Residence, Palace and World Wonder villages are excluded for gameplay reasons.

I activated Plus, but production did not increase.

Plus does not include production bonuses. You must buy +25% for each resource separately in Plus functions.

Do I need Plus to use other features?

No. Every gold feature works standalone as long as you have enough gold.
