Category Quiz is a trivia game that challenges you to answer questions by category. With over 10,000 questions available in English and German, this game will keep you entertained for hours. The game features Google Play Games integration, allowing you to compete with players from all over the world through a global highscore list. You can also unlock achievements and earn experience points by logging in with your Google account.

The game has three modes: Singleplayer, Quick Game, and Normal Game. In Singleplayer mode, you must answer questions correctly to earn points, and if you answer all questions in a category correctly, you get extra points. However, if you answer a question incorrectly, the category gets locked, and you can't answer any more questions in that category. Quick Game mode automatically selects six categories for you, while Normal Game mode lets you choose your favorite six categories. Additionally, the game features Image-Questions, where you must answer questions with the help of a displayed image. The game also has a multiplayer mode where up to four players from all over the world can compete against each other.

If you have any questions, problems, or crashes, you can contact the developer via email or Facebook. The questions are frequently updated, ensuring that you always have new and exciting challenges to look forward to.
