Heh. I thought since I have a small audience of people here, I figured I’d post this little nugget of a puzzle to you and see if you can figure it out. The concept of the puzzle is very simple, but the solution is far from that. Read on if you dare….
This is the puzzle. It’s been slightly modified so that numbers can be used to show what moves you are making. The original puzzle has rounded sides instead of points but the points make it easier to distinguish between moving from 1 to 2 and moving from 1 to 6 to 2.
The puzzle works like this. What you want to do is create the above image without ever going over the same line twice or lifting your pen off the puzzle (allowing you to move to another spot). Which means, you should be able to make this design in 10 moves where going from 1 to 2 counts as a single move and then going from 2 to 7 to 4 counts as a single move (since from 2-7 you MUST go to 4).
I was shown the puzzle when I was in grade 8 and have never been able to solve it and I personally believe that the puzzle has no solution but someone out there may be able to find a unique way to solve it.
I wrote a computer program back in the late 90’s which never found a solution. I recently re-examined my code to find that it was flawed and re-wrote the code to fix it. I figured the program would find a solution in no time at all but no luck so far.
How good are you at puzzles?
