GUESS WHO

This game uses a binary mechanism, allowing you to ask yes/no questions and adjust the accuracy of responses. Your goal is to correctly identify the character with the fewest guesses.

How to Play

• Set your privacy budget to determine accuracy of the response by adjusting the epsilon value.
  For example, with ε = 1, there is a 27% chance the response could be a lie!
• Ask your question
  Q: Is the person alive today?
• Get the response (which might be inaccurate, based on your privacy budget)
  A: Yes

NOTE

Your total epsilon spent before you get the right answer will place you on the leaderboard—the lower your epsilon, the higher you rank!
But remember, lower epsilon means less reliable answers.
