雑学クイズ大臣, developed by 株式会社GZOE, is a popular trivia game that celebrates its 3rd anniversary. With a simple rule of answering questions and clearing 5 within the time limit, players can earn points and unlock various titles. The game features a range of questions, from general knowledge and interesting trivia to extremely difficult puzzles, with over 5000 questions in total. The gameplay is easy, with players tapping on the answer they believe is correct. However, beware of incorrect answers as they will decrease the time limit.

The game includes various question formats, including text-based questions, image-based questions, and multiple-choice questions with more than two possible answers. It covers a wide range of topics, from everyday knowledge to obscure facts, history, entertainment, and subculture. After completing a quiz, players can review the questions and answers.

For players who find the game challenging, there is a roulette feature that allows them to obtain helpful items. These items, such as reducing the number of choices or lowering the difficulty level, provide support for beginners. Players can also earn points and unlock titles, which can be shared on social media or registered on the leaderboard for nationwide competition.

As players achieve milestones and complete achievements, they unravel the mystery behind ancient wall paintings that hold the secrets of the quiz. The game also offers a premium subscription service, "大臣プレミアム," for $110 per month, which provides an ad-free experience and increases the number of times the roulette can be spun to twice a day.
