a couple of weeks ago I found this interesting little game at miniclip.com
http://www.miniclip.com/games/5-in-a-row-gomoku/en/
the rules are very simple ...
you place one stone and the opponent places another one ... the first one to make 5-in-a-row wins
this game is interesting because even though the concept is very simple (like tic tac toe) , if you play a couple of games , you will realize that there is quite a bit of strategy in it
(also , if you want to , search for "Earthian" in the search box in the game and if I am online maybe we can play a match together)
