Clash of Clans is a game where people have to build a town hall (the main part of the base). Then they must build defenses like cannons, archer towers, wizard towers, mortar, walls, and more.  The main point of the game is not to let the enemy  destroy your town hall or get 50-100% on your base. Another objective is to get as many trophies as possible that way you can rank up in leagues. People have three divisions in each league. The best league is champion, that is pretty hard to get. There is a story mode where you have to get the goblins that raided your base and raid all of their basses. Once you beat that you get gems. Gems let you buy shields, speed up stuff, and make things upgrade instantly. The best barracks that you can have is dark barrack, they unlock creatures that are almost invincible. The only way to get the dark barracks is to upgrade the town hall. When people upgrade their town hall they get better things than what they had. The best way to upgrade your town hall is by raiding people online.
