Sister game to [Tetris Max][1], Columns Max is a decent nab at the
'Columns' genre that sees you dropping sets of three coloured blocks
(stacked vertically) into the play area. Blocks are removed from the
play area by matching three or more of the same colour horizontally,
vertically or diagonally.
