Metro Lines is a simple matching game based on a grid-style board. Circles in different colors are randomly placed on the board and you need to move one circle at a time. In your basic easy mode, once you match three circles of the same color either vertically, horizontally, or sideways in a set of three or more, the circles will clear. If you successfully clear a set of circles you can then move another circle. If your move results in no match, then a few more random circles will appear.
