Clash of Clans is a title that combines elements from multiple genres. Besides the engaging gameplay, it's popularity, and the social aspect that guilds provide, it may be one of the most balanced MMO base-building games on Android devices.
Build, recruit, battle repeat
This game does a variety of different things well. You have to balance base defence with resource production, and choose whether to build something or recruit units because both will cost one or more resource types.
Balancing resource allocation is also important because you can earn things by raiding other player's bases. Some buildings generate stuff you need, but this is a more passive measure of acquiring elixir and gold.
The game allows players to form a confederation of 50 people. Besides socializing, you can donate troops to other people in your guild and participate in Clan Wars that allow you to earn bonus loot.
Freemium mobile game
Although this is a free to play game, as you get farther into the game, things take longer and longer to do. This may force players to either spend real-world currency to purchase this programme's premium currency, or sit and wait for timers to expire. Even with that in mind, the management and social aspect of this game has drawn gamers to this title for over six years.
