What do you think you are best at?
Here is your chance to prove it. Go in, take on quiz after quiz, and show that in sport, in art, in your own trade, in general knowledge you are not good — you are the best. Post your score, let the rivalry warm up. Set out across the map and take it, one subject at a time.
And remember: in the very thing someone else calls their strongest, you might be the stronger one.
Most trivia games hand you a score and forget it. masterID keeps it. Every question you answer feeds a profile that records the subjects you have mastered, the weeks you have won and the ground you have taken — an identity built out of knowledge instead of a number that resets tomorrow.
EVERY SUBJECT, WRITTEN BY HAND
History, geography, science, music, film and television, literature, art, medicine, architecture, sport, politics, automotive and more. Every category opens into collections, every collection into quizzes, and every quiz into easy, medium and hard levels. Tens of thousands of questions, each one written on its own rather than scraped — and more with every update. Country collections sit alongside them, for Türkiye, Ireland, the United Kingdom, Spain, Mexico, Latin America and the United States.
WAYS TO PLAY
• Journey — fifteen stations of a single long road, level by level, with a boss check at the end of each one. Progress is logic before trivia: the questions are built to be reasoned out, not only recalled.
• Academy — the whole library, open. Choose a category, choose a collection, choose your level, and watch your conquest map fill in as each one falls.
• Quick Play — a short round when you have five minutes, mixing three question types in every session.
• Spin Wheel — let the wheel choose your category and your game type. Ten slices, no two rounds alike.
• Duel — face another player's recorded run, question for question, and see the gap close or open as you answer.
KINDS OF QUESTION
Multiple choice. True or false, thrown left or right as a card. Fill in the gap. Put the events in the right order. Match the pairs by drawing the wire between them. And rapid maths, where the clock is the opponent.
COMPETE EVERY WEEK
A league that resets every Monday, so a bad week is never permanent and a good one is always in reach. Alongside it: all-time standings, and separate boards for Academy and Journey, because a specialist and a generalist should not be forced onto the same list.
PLAY THE WAY YOU LIKE
Time attack, chain runs and the classic timed round rotate through the light modes. Jokers get you out of trouble: remove two wrong answers, buy back a few seconds, or skip the question you were never going to get.
THREE LANGUAGES
Turkish, English and Spanish — every question in all three, switchable at any time from Settings without losing a thing.
FREE TO PLAY
masterID is free and supported by ads. No account is needed beyond a handle and a password, no phone number is asked for, and everything you have earned can be exported or deleted from Settings whenever you want it gone.
