Guess My Number

Who am I? I’m a math guessing game you can play with friends!

Choose a number the other player will have to guess by asking you questions. You can only answer with yes or no!

The goal is to discover the other player’s number while asking as few questions as possible. Which questions should you ask to find the number quickly? What properties of natural numbers can help you? Strategy and arithmetic are your best allies! And why not turn this game into a tournament?
