Line-Up Variety is an implementation of popular well-known game Connect Four. This is a connection game where tokens are dropped into vertical slots. Typically 7×6 board is used, while the winner is the one who arranges 4 consecutive tokens of own colour vertically, horizontally or diagonally. A game results in a draw when the board gets full while none of the players could succeed. The application also supports 9×6 board where 5 consecutive tokens are required to be formed in order to win.

Other supported features:
- Prefill board: edge slots are prefilled with tokens of alternating color;
- Cylindrical board: the board is considered to be a side surface of a cylinder, so the edge slots become adjacent to each other;
- Popout mode: remove a token instead of dropping it;
- Optional time limit for a game.

The application allows to play against either the computer or a human opponent over local or Game Center network. Voice chat is available over Game Center network.

Total scores of Human against Computer games are maintained.

The application is offered free of charge without third-party advertising or other restrictions.

A separate release is available for iOS 10.0 and above.
