If you like geographical quizzes then SPB Geo Game is well worth taking a look at.
SPB Geo Game puts your knowledge of World capitals and national flags to the test. It's very simple to play in terms of its controls. To get started you simply tap either the 'Capitals' or 'Flags' game from the main menu to get started.
The basic principle of both of the tests in SPB Geo Game is to answer as many questions correctly as you can in one minute. All of the questions are multiple choice, and you just need to tap one of the four answers (or one of the four flags in the case of the 'Flags' game). Once you get the answer correct an animation of the Earth loads, showing you exactly where in the World that place is. This gets a bit annoying after a while, but don't worry because you can turn it off in the options menu.
SPB Geo Game is fun to play, but after a few goes you'll find it gets quite easy. That's because questions repeat themselves quite often and you get to know what the answers are. Still, I guess that's what learning is all about.
If you think you have a good knowledge of the World, or just want to brush up on your geography then you should find SPB Geo Game helpful and enjoyable.
