Connect4

Connect4 is a single player, freeware game that is played entirely with the mouse.

Connect4 is a conversion of the classic board game and it is played on a vertical board of seven columns and six rows. The player and their AI opponent take turns dropping coloured stones in the board to form four in a line horizontally, vertically or diagonally. The first to score a line, wins the game.

The AI opponent's skill level can be adjusted, a game can be saved and loaded, and individual moves can be undone, there are also optional sound effects - a clunk as a piece is played and applause at the end of a game.
