This app is a Question and Answer game (QUIZ) aimed at testing and strengthening your knowledge. You are nominated for the Apapane mission. The mission is to represent the planet Kleper next to the planet Earth. You will be aboard the Castore ship. The computer that controls the generation of energy has been programmed to act according to the results that you will demonstrate during the trip. The goal is to show that you have knowledge about planet Earth. The journey is made up of 7 levels. In level 1 and 2 the questions will be randomly chosen. At level 3, questions are linked to figures that will be displayed. At level 4 and 5 you can choose which subject will be questioned. In level 6 and 7, the letters that form the answer will be mixed with other letters, you will have to select the correct letters. There will be a set time to answer each question, and this time may vary from question to question and from level to level. Question not answered in time will be considered wrong and processed as such. Each level has a minimum number of hits to be obtained. From level 1 to 6 you can get a maximum of 2 points per level, and they are cumulative. For example: Level 1 hit 100%, earned 2 points. You will start level 2, being able to miss 5 questions out of the 15 that will be asked to advance to level 3. If you also get 100% correct in level 2, you will have 2 more points and will start level 3 with 4 accumulated points. And so on. Points will be indicated by the figure of diamonds. At level 7, you will have to get 10 questions right. If you reach level 7 without accumulated points, any error means that the mission failed. If you reach level 7 with 3 points, it means that you can miss 3 questions, but you still have to get a total of 10 questions right. The questions cover: General Knowledge, Geography, Sports, History, Literature, Exact Sciences, Biology, Chemistry, Film and TV, Music, Arts and Paintings, and Tourism. The application allows you to restart the game in general and by level. You have the option to reactivate the wrong questions per level. Questions you get right will no longer be displayed. The app allows all questions to be reactivated. Periodically new questions are made available. Come test and increase your knowledge. Good luck !
