Columns , developed for the Sega Genesis console, is a puzzle game where players must arrange groups of 3 same-size but varying color blocks into sequences of 3 or more to clear them. Sequences of 4 or 5 count for double or triple points, and diagonal sequences score the most.
The real challenge lies in setting up 'combos' - where one line causes other blocks to drop so as to create other lines. Players can also try their hand at the 'flash' mode, a variation where they aim to remove a specific block from the base of a pre-formed pile of bricks, with varying levels of difficulty.
