Columns , released for the Sega Game Gear on October 6th, 1990, is a puzzle game where players must arrange groups of 3 same-size but varying color blocks into sequences of 3 or more, either horizontally, vertically or diagonally.
The goal is to create 'combos' by clearing lines, which in turn causes other blocks to drop and create even more opportunities for clearing. The game also features a 'flash' mode, where the aim is simply to remove a particular block from the base of the pile of bricks.
