Single Line Connetor

At first it may seem pretty easy, but once you have passed some levels, the challenge will increase.
Your goal is to draw a line to connect all points with each other. The main challenge is that you can’t draw twice through the same section of the line, so observe the figure and try to think what’s the right point to start with.
The higher the level the more dots you will have to manage and the more challenge it brings. If you get stuck on a level, use a hint which will help you to proceed correctly.
This game is not only fun to play but also helps in improving your imagination and thinking capacity.
