Columns is a match-three puzzle game developed by Sega for the Sega Genesis console. Released in 1990, the game challenges players to manipulate columns of three differently colored jewels as they descend from the top of the screen. Players must strategically align jewels horizontally, vertically, or diagonally in groups of three or more to clear them from the board and earn points. The game features simple but addictive gameplay, vibrant graphics, and an Eastern-inspired soundtrack. As the game progresses, the falling columns descend faster, increasing the difficulty. Its genre is primarily puzzle.
