The Tribal wars is a multi-player browser-based online strategy game, absolutely free of charge, you only need a username and password. On this game you especially have to build your village and create how many troops you can because you never know when the enemy strikes. You are able to associate with a tribe, and in that manner you will be protected along with you mates from that tribe, but you also have to defend them if needed.
However, Tribal wars turns to be a really good game based on strategy and availability, although, in my case, the village I had, along with the crops and troops were destroyed due to a raid, even if I was online at that moment and I could see them coming, I could do nothing to save my work for months. All that happened because a tribe attacked my tribe and surrounded it.
Basically, this game is well-known in the strategy game niche because of its graphics and because you are not competing with a computer, but with other players.
