Tactic

Tactic is a falling block puzzle as popularised by the game Tetris. Unlike that game, all of the blocks are the same size but are a number of different colours (and on systems that cannot display enough colours, different shapes). g. a line in a set direction or a cross).

The patterns required to complete the level are shown at the bottom of the screen. If a required pattern is formed, those blocks disappear causing any blocks resting above to fall. The iOS version adds bombs.
