4 connect (e)

From Gravopedia

Connect 4 is a two players game which takes place on a 7x6 rectangular board placed vertically between them. One player has 21 tiles and the other 21 red tiles. Each player can drop a tile at the top of the board in one of the seven columns; the tile falls down and fills the lower unoccupied square. Of course a player cannot drop a tile in a certain column if it's already full (i.e. it already contains six men).

The object of the game is to connect four men vertically, horizzontally or diagonally. If the board is filled and no one has alligned four men then the game is drawn (i.e. after 42 moves if no one wins).
