The classic connect-the-line drop game
Four in a Row is the familiar gravity-drop connect game: 7 columns, 6 rows, and a simple goal, get 4 of your own discs in a line before your opponent does, horizontally, vertically, or on either diagonal. Play against the built-in AI at 3 difficulty levels, from a random Easy opponent up to a Hard opponent that searches several moves ahead and fights for center control, or switch to 2 Player mode for local pass-and-play with a friend.
Part of the same Classic Board Games collection as Triple Threat (tic-tac-toe) and Kings Row (checkers), sharing the same consistent AI difficulty system, top-down table view, and sound design.
