FLUX is a unique and addicting game. Unique because there isn't anything out there quite like it. Addicting because it challenges everyone that has played it, from 8 to 80. (Yes, we really had an 80 year old play the game! We couldn't get her to stop playing the game! We finally had to call the paramedics because her pacemaker was being affected by all the radiation from her monitor). You start with a simple 7x7 playing grid (49 squares). Inside the playing grid are 2 red flux pieces (human player) and 2 blue flux pieces (computer opponent). Also inside the grid are four or more blocks. These blocks serve no purpose, other than to limit movement and occupation by the flux pieces. Flux will work on most PC's and Compatibles. A VGA monitor and a mouse are required to run FLUX.
