Wikipedia launches its daily historical facts game “Which came first?” for iPhone users. The game arrives through an update to the Wikipedia iOS app released today. It is available inside the app’s Explore section and presents users with history trivia focused on ordering events by date. The gameplay centers on placing historical events in the correct chronological sequence, using notable events associated with specific dates from history. The service provides five new challenges each day, and players can also revisit earlier quizzes through an archive. The app tracks user performance, including statistics such as average scores and streaks. Multiple outlets report that the feature was introduced previously on Android, and that iPhone availability follows about a year after the Android launch. Overall, Wikipedia positions the update as part of the daily engagement features within its mobile app, offering a recurring quiz format rather than a one-time set of questions.
