Masters of Trivia is an online picture trivia game. You play it in real time against everyone else.
The game is a quick, time based game, you want to answer as many questions as you can in 40 seconds. When the time is up, your answers and the high scores are shown before a new game starts.
If you keep answering correctly, the point value for each question goes up but as soon as you get one wrong, it goes back to the starting value (a lot like the TV game show The Weakest Link).
If you get stuck you can use hints to remove a wrong answer. Hints cost 10 or 15 credits, you can earn credits by adding questions, getting all the questions correct in a game or winning the weekly masters tournament.
