Columns was one of the many tile-matching puzzle games to appear after the great success of Tetris in the late 1980s.[12] The game itself is enclosed within 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. After a column lands, if three or more of the same symbols are connected in a horizontal, vertical, or diagonal line, those symbols disappear. The pile of columns then settles under gravity. If this resettlement causes three or more other symbols to align, they too disappear and the cycle repeats. Occasionally, a special column with a multicolor Magic Jewel appears. 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, which ends the game. Players can score up to 99,999,999 points.[13]
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.
Ports
Sega ported the arcade game to the Mega Drive/Genesis console. This version of the game was nearly identical to the original arcade game.[9]
Columns was the first pack-in game for the Game Gear. This version was slightly different from the Mega Drive/Genesis version and its soundtrack was transposed and rearranged due to limitations of the handheld's sound chip. While the columns themselves were updated for the Mega Drive/Genesis version, the overall decoration was less like a cartoon in the Game Gear version and instead more artistically designed. Lastly, the Game Gear version had a feature that let the player change the jewels to fruit, squares, dice, or playing card suits (clubs, diamonds, spades, and hearts).
Reviewing the game's appearance in Sega Arcade Classics for the Sega CD, Glenn Rubenstein gave it a B+ rating in Wizard magazine, describing it as "like Tetris but a bit better".[23]Mega placed the game at number 34 in their "Top Mega Drive Games of All Time".[29] In 2017, Gamesradar ranked the game 40th on its "Best Sega Genesis/Mega Drive games of all time".[30]
