If you are running a reasonably recent version of Netscape Navigator or Internet Explorer, you can see this and similar MicroWorlds Logo projects after downloading LCSI's free plugin, Web Player .

Once LCSI's Web Player is installed, come back to this URL and play the graph game of Sim or one of its equivalent forms. (Please wait a minute for the game board to appear below. Sometimes you have to click in a different place on the dot to color it red.) Afterwards, you might want to learn more about the games.
