When you first start on Clash of Clans, you are given a tutorial. Note that you don't have to spend the gems it recommends and you do not need an army of wizards to take out the goblins. After you have completed this tutorial and got to grips with the game, you have several looming problems.You will have a three day shield, this is essential in getting your defenses and resource buildings to a safe level before being attacked. The first thing you need to do is upgrade your Elixir Collectors and Gold Mines to a sensibly high level. I recommend at least level 3 or 4 at first. This will give you enough of a resource base to keep you going for a while. Don't worry too much about Barracks and Army Camp upgrades at this early stage as they won't protect you from invasion and will only help when you are on the offensive, but do try and get your Town Hall to level three.As soon as you have completed these tasks you must turn to your defensive buildings.
You will already have a cannon from the tutorial but apart from that, your first defenses need to be your most important ones, walls. Use all your walls around your buildings, bear in mind that the buildings that are most valuable are your storages and your Town Hall, make sure you can surround your storages and town hall completely but remember that enemies can spawn in the corner too, it's not safe to build with no walls in the corner.Surround your base with the less important buildings to slow your attackers and upgrade your walls to at least level 2.When you are confident your base is stable, completely free clash of clans hack begin Town Hall level 4 upgrade and begin building your cannons and archer towers. Upgrade them as much as possible and save up to get a mortar as soon as you can. Put the mortar with your TH and your storages in your walls and keep upgrading them. You want to fit as many of your defensive turrets in your walls as you can whilst keeping your less useful ones outside your base. Keep upgrading your walls and your turrets and you are ready to face the world.
Since your three day shield is such a blessing, it is not advised that you break it early. Once it has run out however, you are ready to go out in search of trophies, gold and elixir.
Attacking involves three fundamental parts each covered in depth here, they will be explored later in terms of applying them at higher levels. After beginning and finishing Town Hall level 4 upgrade, build an Air Defense as soon as possible and begin to upgrade your defensive buildings in this order - Mortar, Archer Tower, Cannon . Once Mortar is level 2, begin your Archer Tower upgrade. Once that is level 4, start your Cannon upgrade. Once that is level 5 (This may take some time), try to max out your walls and put everything neatly in place.
