Q.	What am I supposed to do? :)
A.	Note - there are no crossings or loose ends. There is only one line which is continuous.
Q.	What are these numbers for?
A.	Each number indicates exactly how many lines should be drawn around it. Cells which do not have numbers inside can be surrounded by any number of lines.
Q.	What is not allowed?
A.
Q.	Where do I start?
A.	Think logical. As an example take a look at this pattern: There should be no lines arround the 0. So you can mark the lines arround the 0 with an X (use the right mouse button): There is only three lines possible to draw arround the 3. Then the lines can only continue in these directions: You will discover more patterns like this with the time.
