★ Top Developer, almost 2 million downloads of Four In A Line!

While a fairly modern game compared to classics such as Chess or Backgammon it is believed to have developed during the nineteenth century. The aim of the game is quite simple: connect 4 or more pieces in a line vertically, horizontally or diagonally. It sounds easy, but one bad move can ruin your chances of winning drastically so watch out for that sneaky computer - it will beat you if you're not careful.

Cant see which move to make then try the hint function. Didn’t see the last move, ask 4-in-a-line to show it again. View the game info, game statistics….ok, that’s enough of the 2020 visual puns.

With support for over 16 levels of game play, you are sure to find one that exercises your mind to its limit.

* Simply connect 4 in a row before that sneaky computer
* Play against the computer or another human player on the same device.
