Geo I Know - US Edition for Android
The game utilizes natural earth maps with seven zoom levels: both beautiful and realistic, but difficult, since you have no other state border context to help determine the correct answer. You can learn accurately the locations of cities and states as they look from space.
With four difficulty levels, from easy to brain-crushing, you can set games to 10, 25, or 50 questions, and question time limits of 10, 30, 60, or 90 seconds. Choose Teach Me mode to see the correct answer if your answer is wrong. With over a million questions, you won't soon run out of quizzes to challenge your US geographical knowledge.
Technical facts:
"One miss" mode allows one wrong answer, but halves the score.
Fully movable map in all 4 directions (north, south, east and west), like in Google Maps(TM).
Play in portrait or landscape mode.
All screen sizes are supported.
External memory installation or migration supported.
Smart map caching reduces data transfer during the play.
