This will be a very straight forward puzzle accessible to anybody with no special skills required.
In this grid of dots, draw 12 straight lines and connect all the dots. The lines must be drawn end to end (imagine making the lines with a pencil and not ever picking up the pencil). The lines' thickness can't help with the puzzle; for all intents and purposes the line thicknesses are infinitesimal. The lines must also go through the center of each point.
1) No putting the grid on a non-flat surface
2) Post a picture of your solution (the lines can be thick but the thickness can't help with the solution)
