Every question has a difficulty on the same scale as your rating. Your rating goes up when you answer faster than expected for that difficulty, and goes down when you answer more slowly or skip.
The next question is picked near your current rating. A new player starts at 800. Questions start with one die or one card and move on to several draws, several dice and conditional probability.
Answers
Answers are fractions in lowest terms, so 1/4 is accepted and 2/8 is not. A decimal is also accepted when it is exact, such as 0.25 for 1/4.
Listen Mode
In Listen mode each question is read aloud and not shown, as it is when an interviewer reads a question out. Listen mode has its own rating. Press R or Repeat to hear a question again.
