Columns
1990
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.
