Lines shouldn't have to go in to nothingness. For that reason, they need you to make sure all of the lines on the Cubiq connect. By using the WASD keys, you can spin the Cubiq around in order to get a different viewpoint and to see the rest of the lines. The lines can be moved by simply left clicking on the square the line resides in. There are 10 levels and if you can complete the 10th level, you are a very talented and logical individual. This is unlike any other puzzle game you've run across, because instead of it being 2d, it's 3d which make the options of line connections nearly unlimited.
