Starlink is a really awesome game! The goal is to create more boxes than your opponent. You get to click 1 line at a time. The way I usually play is to put lines a bit randomly. 🙂 To make a box yours you have to click the 4th side of a box that already has 3 sides. It doesn’t matter if your opponent helped create a side of the box, as long as you finish the box, it’s yours.
