 Gridlock is an interesting free flash puzzle game. There are a set of blocks which you must slide out of the way of a blue block in order to move the blue block out of the puzzle and into the next puzzle. The puzzles are interesting but the graphics are pretty plain. I've seen similar games like this on the web with better graphics but there is an appeal in this one for being simple. If you like puzzle games give this one a shot.
