Columns is a Tetris-style puzzle game in which the player moves and changes the order of a stack of three falling jewels, which must be combined and arranged to connect three of the same type of jewel. The three jewels can be successfully connected horizontally, vertically or diagonally. The game is over when the falling jewels have stacked all the way to the top of the screen. As time progresses, the speed at which the jewels fall increases, and the aim of the game is to last as long as possible to achieve the highest score. Columns also allowed players to compete against each other at the same time or against the computer in a Versus mode.
This game came bundled with some Sega Genesis game systems.
