US States Quiz is a free game app that tests your knowledge of the 50 US states. There are a total of 10 difficulty levels in the game, and each level asks you to perform a different classification. In the first two levels, you'll be given a state and asked to name its capital. In the third and fourth levels, you'll be asked to name the state associated with a given flag. In levels five and six, you'll have to pinpoint the location of a state on a national map.

Levels seven and eight ask you name the state based on its seal, which can be quite difficult, and the last two levels will give you a state capital and ask you to name the state of which it is the capital. There is no timer associated with each level, so there isn't any pressure. The game ranks the best players with leaderboards that you can access anytime, and you can find out how well you do compared to others with the online rankings.

Thanks to the online multiplayer mode, you can challenge friends and family to quiz levels at any point. This is a great way to help prepare for a test or learn more about your nation.
