Lats night at Buzzy’s Country Store, Duncan Leper showed me a puzzle he said his Dad had shown him years ago. We were discussing different ways to solve problems and Duncan mentioned that “Sometimes you got to think outside of the box.” Then he drew the following nine dots with the challenge to connect all of them using only four lines and never lifting the pen while doing so.
After a couple minutes trying I had him show me the solution which is provided in the following link click here. If you try to do it before checking out the solution remember to “think outside the box.”
