Today's time waster is a simple game with a simple name, but it's lots of mesmerizing fun. Grid Game is a Flash game with consist of a grid of tiles, each of which has a curve on it that can connect to adjacent tiles. You can click on a single tile to spin it 90 degrees, and if it connects with a neighboring tile that tile will rotate 90 degrees, too, and so on in a chain reaction. You get a point for each tile you spin, and though you could strategize, it's much more fun to just cross your fingers, click on a promising-looking tile, and see what happens.
