Strategic Usage
Iron is the currency of construction. As you move into advanced levels, the costs escalate into the millions. It's often smart to keep your Mines one level ahead of your Stronghold requirements to ensure you're never bottlenecked by resources.
Efficiency Tip Always try to synchronize your upgrades. Start long-duration upgrades (like Stronghold or Advanced Storages) before long sleep periods or work shifts.
Storage Priority Never let your Storages overflow. If your resources hit the cap, your Mines and Farms effectively shut down, wasting valuable production time.
