Columns is loosely derived from Tetris, as it involves arranging falling blocks in such a way as to clear them. However, in columns they are groups of 3 same-size but varying color blocks, which must be arranged into sequences of 3 or more, either horizontally, vertically or diagonally. Sequences of 4 or 5 count for double or triple points, and diagonal sequences score the most. The real trick is to set up 'combos' - where one line causes other blocks to drop so as to create other lines.
The gameplay in Columns is addictive and challenging, requiring strategy and quick thinking to progress through levels. As players navigate the different modes, they must carefully plan their moves to clear as many blocks as possible while avoiding obstacles and maintaining a steady flow of combos.
