Terms To have any chance of being successful in this game you need to know the terms that are used. When you have learned all these terms the game will start to become a little bit clearer.
Buildings Have some buildings in your base when you are ready to configure it as this helps fortify your defenses and can get you more cash in the long run. Try to level your buildings up to the max whenever possible. To upgrade a building simply tap on it to bring up an option to upgrade it.
Energy Your energy is near the top of the screen and is indicated by a blue bar marked by lightning. During the early stages of the game make sure you spend most of your Skill Points on energy so you have maximum output. If your energy runs out you can refill it by either waiting for it to reload or by buying more with Gold bars.
VIP Section Whenever you buy 10 Gold bars you will gain VIP status which will enable you to join players you don't know in battle. Every player is allowed to invite up to three VIP players to their squad. Make a point of collecting cash from your allies by hitting that 'Visit Allies' button.
Alliance Codes To be successful in this game you need to be part of a strong community of players who each help each other in battle. Every player is issued a 9-digit Alliance ID and you will be able to bring four separate Alliance partners with you into battle. Make sure though that you do not add more than 1,000 allies otherwise you will lose them all.
Rivals You can get more money and Valor points by raiding rival bases. If you do this though expect to get raided in return.
Money Make sure you keep an eye on your earned income by checking your assets in your profile.
Boost Units Try to regularly participate in live events as this is the only place that you can earn Boost Units.
