How can you connect 9 dots using for lines without lifting pen.

• I guess its using"four"lines..use a paper this. Take a paper, fold it from both sides leaving space in between...such that you can see that the paper has 3 divisions(folded ones being upper divisons)..on the folded part make 4 dots one after another in a line,i.e 4 on left folded part and parallel to that 4 on right part...8 dots have been made..now place one dot in between any two dots..join all the dots. ..u can see their is no requirement of lifting ur pen.the movement of hands is just like writing an inverted"S"..unfold the papers both sides...u can see on the lower part of paper, it only 4 lines and u have connected all the dots..
