AboutRohit Agarwal Expertise I can answer questions related to numbers and logic easily. However I sometimes face problems when solving questions that require a lot of creative thinking. I am not good at puzzles which involve a play with words, so please don't ask me to solve such puzzles for you.
Experience I have read a couple of good books containing puzzles and can now claim to have an "expert" in this field. I have been invited to become a member of Mensa.

Awards and Honors Numerous certificates recognizing my ability in Mathematics and Logical Thinking
Question I've been struggling with this one since taking a statistics course in University in 1976. I'll try to draw the puzzle as it was presented to me:
* *
* * * *
* * * *
* *
The challenge is this:
Join all of the dots along the horizontal, vertical and diagonals (resulting in an image looking something like 5 envelopes adjacent to each other) without retracing any line, by using just five continuous lines. I hope I've explained that adequately. The resulting image is like this:
*--*
!\ /!
!/ \!
*--*--*--*
!\ /!\ /!\ /!
!/ \!/ \!/ \!
*--*--*--*
!\ /!
!/ \!
*--*
Not very good, but the best I can do with the typeface. I think you'll get the idea. I've been "doodling with this for over 30 years and can always do it with 6 lines, but have only (I think) done it a couple of times with 5 (maybe I was dreaming?)
Was I dreaming, or is it actually possible??
Regards,
Jim

Answer I don't know if I've understood your question properly or not. But in case I have, then I have a solution.
First lets assign a variable to each of the dots to help us communicate better.
a b
c d e f
g h i j
k l
line 1 - from c to just right of f (covers c,d,e,f)
line 2 - from just right of f to below k (covers j,l)
line 3 - from below k to above a (covers k,h,d,a)
line 4 - from above a to just right of j (covers b,f)
line 5 - from just right of j to g (covers j,i,h,g)
In case this is not what you are looking then please don't hesitate to post again.
