This game is an upgrade of the original 1990 arcade release of Columns.
The games were released out of order for some reason — this one was released a few weeks before Volume 6, unless Sega, 3D-Ages, and SCEJ all accidentally switched the dates on both their websites.
This game include an `original mode` (which is practically identical to the arcade release) and an updated mode, sporting pre-rendered 2D graphics and various visual and audio upgrades. There is also a versus mode where you can play against the computer, otherwise it is not too dissimilar from the original version.
