This guide features the solutions for every 50 level in Line X Free puzzle game as of 2019.
Try starting the levels with finding the path for the most obvious circles. Some of the circles are placed in a way that they have to be connected following a certain path, because trying to link them together otherwise would cause blockages in the pathways of other circles. And this is the only tip you will need for Lines X as it’s already a pretty simple puzzle.
Note that the solutions are not definitive, meaning that there are more ways than just the specific ones here or in other guides. You can easily just use these solutions as a base to come up with your own. As long as there are no available dots left on the map, your solution is also correct.
