Market Making

Game Rules

Each question presents a probability-based scenario (e.g. “What’s the chance a coin lands on heads at least twice in 3 flips?”). Your task is to act as a market maker and input a bid price (lower estimate) and an ask price (upper estimate) for the true probability.

​

🏆 Scoring

• If the true probability is between your bid and ask, you earn Bid/Ask points.

• If the answer is outside your range, you lose 1 point.

• If your answer is invalid, or left blank, you lose 2 points.

 

You have 30 seconds per question, and the game consists of 10 questions.
