Connect Four is a digital version of the 1974 Milton Bradleyboard game of the same name. In the game, players take turns dropping coloured discs on a vertical playing field while trying to get four of them in a row either horizontally, vertically or diagonally.
The gameplay is straightforward: each player takes turns dropping discs into an empty column. The goal is to get four discs in a line before your opponent does.
Players can choose from different colour options and play against the computer or a friend on three difficulty levels.
Connect Four was released for the CD-i console in 1970.
