I think most around here will know the answer to the house with the x in the middle, which you have to draw with one line, but there also is a puzzle in which you have to draw two of them next to eachother in one line. Is this possible? And if not, can you prove why it isnt possible?

There are no comma's in the numbers themselves

But If the number would be 9 or 999, the answer to your question would be 'no'. So you would only find out if the number is 99

I am thinking about one number, it's 9, 99 or 999. You can ask one question to me on which I can answer yes or no to find out what number I'm thinking of. What question do you have to ask? Anyone know the answer?
