When starting out, focus on resource building in order to keep your supplies filled. Improving resources that will allow you build more upgrades, produce more offensive units, bring in the best defense. You do not have to worry about defending your kingdom until you are making lots of money and resources. In the early phase, strategy is less important than sheer numbers. Deploy as many cheap troops as possible, even though they are week. To do this, upgrade your Military Schools to generate good numbers of units. Use this tactic in multiplayer mode, where many opponents may not have the complicated defense needed to counter large numbers of attackers. As you progress, you will find that the fewer units you use to win, the better. To do this, you must formulate strategies that will allow you to use each piece effectively in battle. By using fewer units you will have some extra units available to deploy for your next attack. This will also keep resources consumption low. Use as much of your area as possible by clearing debris. Expand your area only when you do not have something to buy, and you need to hide your excess resources by purchasing something.
