Four in a row is an on-line variation of classic game. The game is for two players connected on-line and the rules are the same as the classic: each player put one colored disc each turn, ad the goal is to connect four of one's own discs of the same color next to each other vertically, horizontally, or diagonally before your opponent.Each disc has to be positioned above other disc or at the bottom row.We did this app just for fun and to realize how powerful is mixing Android, databases and internet. We do not pretend to do the best 4 on line game, but if there is anything that we can do to improve it or you find a bug, please let us know sending an email. Thanks!
