Build wireless towers by clicking on the highlighted green tiles. Each tower you build extends your reach. Try to block your opponent from expanding by building a wall of towers between them. If you run out of space to build, you lose.
A simple concept, but not well executed. Ah well, maybe next time I'll make a proper playable game for once.
