How do you connect 9 dots in 3 rows with only four straight lines?

The key to this (old) puzzle is to realize that the lines don't have to end on a dot, they can be extended beyond the end of the row or column.
If the dots are numbered
1 2 3
4 5 6
7 8 9
1) Start with dot #9 - draw a line through #5 to #1
2) From #1, draw a line through #2 to # 3 and then continue the line far enough out to be able to draw the next line
3) Draw a line from the end of the previous line through # 6 and #8, ending the line under #7.
4) Draw a line from the end of the previous line through # 7 and #4 back up to #1
See the diagram below (it's not perfect, but you should be able to follow the idea)

Are there any cheats for the game dots?
Assuming you are referring to the game where you connect dots with lines, while trying complete the least amount of squares, there are no cheats. The easiest way to play is to scan the dots to see if there are three lines for every group of four dots, and go from there!
