ixThought that you might enjoy a puzzle to help pass the time today. The image on the left shows the number 9 in Roman numerals.

Your task is to draw one single continuous line and turn this into a 6. Feel free to say if you have solved it and how long it took you, but no giving the answer. I will reveal the solution, and source, on Monday. Enjoy.

Quick Update: Someone has just emailed me another solution, so there are TWO ways of solving the puzzle.

The answer to this puzzle, and 100 others,  can be found in a new kindle ebook called PUZZLED, and is available in the UK here and USA here.


  1. Ahhhh no my first answer was wrong after looking at the first post I got a new answer and it’s definitely the correct one lol.

  2. My first answer is the most obvious, and took 30 seconds or so (I was stuck on the wrong way of thinking until then).
    I’ve got another answer which took another few minutes, but I’m not sure it it will be accepted.

  3. Ok, it’s Monday in Australia, answer time! Like everyone else, I thought I got it in a matter of seconds which confused me and now I’m confused as to what the actual question is even.

  4. I actively thought about it for a few seconds, then started reading the posts. The first solution hit me as I was reading the seventh or eighth post. I’m a fast reader so it didn’t take long. I may have got the answer subconsciously from the posts but not the one I was reading when the answer came to me.
