GridLinx is a "connect" game that demands careful but quick thought in placing tiles together to build the largest connected structures. The more tiles you connect together, the higher the score. Stay alert though, there is a time limit on each round. So if your not quick enough you'll run out of time. When you build a connected structure you are credited both with game points and with more play time. So look for every chance to link your tiles. As you climb higher in levels you will notice that later levels require higher scores to advance. You will also notice new challenges that will keep you on your toes. So, get in the zone and put your puzzle brains on blast!
