Connect Four
The aim of the game is to get four of one's own pieces in a row, either vertical, level or diagonal.
But one cannot place the pieces on arbitrary fields of the play field but only on the lowest free field of a certain column.
The play field stands vertical and the pieces fall down.
The pieces are placed alternately by the players by clicking on the corresponding column.
Who manages to get four of one's pieces in a row is the winner.
