Columns is a match-three puzzle video game, first created in 1989 by Jay Geertsen. Early versions of the game were made and ported among early computer platforms, and then the Atari ST, until 1990, when Jay Geertsen sold the rights to Sega, where it was ported to several Sega consoles.
Columns was one of the many Tetris-like puzzles that appeared after that game's great success in the late 1980s. It takes place inside a tall, rectangular playing area. Columns of three different symbols (such as differently-colored jewels) appear, one at a time, at the top of the well and fall to the bottom, landing either on the floor or on top of previously-fallen 'Columns'
While a column is falling, the player can move it left and right, and can also cycle the positions of the symbols within it.
If, after a column has fallen, there are three or more of the same symbols connected in a straight line horizontally, vertically, or diagonally, those symbols disappear. The pile of columns then settles under gravity. If this causes three or more other symbols to become aligned, they also disappear and the pile settles again. This process repeats as many times as necessary. It is not uncommon for this to happen three or four times in a row - it often happens by accident when the well is becoming crowded. If the well fills beyond the top of the screen, the game ends.
Occasionally, a special column called the Magic Jewel Column appears. The Magic Jewel flashes with different colors and when it lands, it destroys all the jewels with the same color as the one underneath it.
The columns fall at a faster rate as the player progresses. The goal of the game is to play for as long as possible before the well fills up with Jewels.
Some ports of the game offer alternate game modes as well. 'Flash columns' involves mining their way through a set number of lines to get to a flashing jewel at the bottom. 'Doubles' allows two players work together in the same well. 'Time trial' involves racking up as many points as possible within the time limit.
