Description

From the listing uploaded by “appupdater”.

The concept of this strategy game is centuries old... It is said that Captain James Cook used to play a variant of 4-in-Line with his fellow officers on his long voyages, and so this game has also been called "Captain's Mistress". The contemporary version of 4-in-Line was launched at the beginning of the 70s. It consists of 7 columns, each 6 pieces high. This game is a neat conversion of a classic game where the aim is to connect four tokens in a row, either horizontally, vertically or diagonally, while keeping your opponent from doing the same. Sounds easy, but it is not! The "vertical" strategy you need to play 4-in-Line creates a unique challenge: you must think in a whole new way to block your opponent’s moves. As any successful game, 4-in-Line has been ported to numerous platforms. So why should you give our version a try? We largely tried to recreate a full experience of the game in a tiny package, including powerful AI engine with 3 different difficult levels, ability to play against other person or the phone, undo and hints Don't forget to check our Games section for more fun time killers...
