Country Flag Quiz
Match the country name in the popup menu to the flag at its left. Control the number of flags with the slider. Use the popup menu to restrict the quiz to a region of the world. Advance the new game slider to see a new game.
The snapshots show different-sized games and different regions selected. When all correct answers are selected, the background changes and a sound is played. When the mouse is placed over the text "Answer", the display indicates whether the corresponding answer is right or wrong.
The code could be easily modified to quiz on capitals or other properties of countries. It could also be modified to give quizzes on graphs, derivatives, etc., if you develop a database of quiz items.
