A somewhat interesting 2 player
game that is played on the computer. Each player takes turns putting a stone on a 8 by 8 grid. Each time the player completed a
square, he got points. All four corners of the square must be your own to get points. The bigger the square, the more points. Finishing multiple squares with a single stone also resulted in more points. Squares can also be on angle. It may seem very simple at first, but after playing for a while, you find ways of setting up multiple squares at once (in which your opponent has to fiqure out which square to
block) and other interesting ways of hiding almost finished squares.
AOL used to have this for free in their games section, and it was the only reason why I stayed with AOL for as long as I did, however, several years ago, AOL yanked it, and I've never used AOL since.
