Grand History Quiz

The Grand History Quiz is a quiz about important dates in world history. The goal for the player is to choose a correct date for a displayed event. The wrong answers are created randomly but the difficulty level settings affects the interval between them and the correct one. So on the hardest level you need to know the exact date of the event but on the easiest knowing in which century it happend should be enough for most questions. Because the quiz has more than 200 events so I divided them by their importance. In the future the quiz should have many extra categories but for now I added only one-History of Poland (87 events).
I know that importance of events is VERY subjective thats why I included a feature allowing users to create their own dates quizes. They can be later used for selfstudy(it really works) or send to me so I can include them in the next app update as user posted quiz.
Have fun.
