Connect all 16 dots without lifting your pen off the paper and using only 6 straight lines.

And you can't touch the same dot twice.
 
This is one pain in the rear, but the higher I got the easier it became.

This puzzle is possible without crossing the same dot twice...look at the bottom right hand corner and top right hand corner, second dot from the right side. Anyone know how?

no clue :confused:
 
As far as the dot puzzles go you can make one as big as you want. For any array of nine dots or more, the minimum number of lines that can be drawn through the dots is can be generalised by a simple equation. If n is the number of dots in any row or column, the minimum number of lines is always 2(n – 1).
For example, the nine dot puzzle has three dots in any row so n = 3.
So, 2(n – 1) = 2 (3 – 1) = 2 × 2 = 4.
For 16 dots, n = 4 and 2(n – 1) = 6.
For 25 dots, n = 5 and 2(n – 1) = 8
For 36 dots, n = 6 and 2(n – 1) = 10
