How to play Reverse trivia

Reverse trivia flips a quiz on its head. Instead of asking a question, we hand you the answer, then show you four clues and you pick the one that actually describes it. You get five rounds a day. Tap a clue to lock it in, then see straight away whether you were right, with a one line note about the answer. On a keyboard you can press 1 to 4 to pick a clue. When all five rounds are done you get a score out of five and a spoiler-free grid you can share. A fresh set of five answers drops every day.

Tips

Picture what the answer is first, then find the clue that fits it best
When two clues feel close, look for the detail that only matches the answer
Categories repeat across days, so a wrong guess today is a free lesson for tomorrow
There is no clock, take your time and think it through
