Strategic Usage
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.
