Clash of Clans or well know as COC the most addictive game I have ever played. This game was made by Supercell and become one of the famous game ever.
Concept of the game was very nice you have to build your village and doing so you have to attack other village for resources. As well as you have to improve your village to defend against attack also. Its has many troops with different power for attacking.
It had a chat feature, with this you can chat with your clanmates and also with global player. You can also get some troops from your clanmate this troops will help you to defend when you are of line.
Now they came with a new update in this you will get another base called builder base with many other troops and some new features.
The layout and design are nice and attractive. You should try once but remember that its a vary addictive game.
