For all the classic board gamers, as well as for those who were searching the site for one the other day, here is a Shockwave multiplayer Backgammon game from Nabisco. A simple menu gets you playing right away, just click on 'Join Any Open Game'. Once there are two players, click the 'Yes' button to start. If no one shows up, you can click the button anyway to play against the computer. If your opponent leaves the game early, the computer will take over. There is even a rudimentary chat system where you can select from a short menu of messages to display. It's not spectacular, but it is a solid implementation that gets the job done. Click.

In fact, Nabisco has several other multiplayer games available to play: Hearts, Spades, Chess and Checkers.
