Tactic is a video game, originally released
for the Acorn Archimedes in 1990 by Eterna.
It takes the form of a falling block puzzle.
== Gameplay ==
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).
The aim of the game is to drop the blocks
so that blocks of the same colour form set
patterns (e.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.
== Release ==
The game was first released in 1990 for the
Acorn Archimedes by Eterna.
It was then converted to BBC Micro and Acorn
Electron by Superior Software.
The BBC Micro version was released on the
1993 compilation Play It Again Sam 17 but
as that was the first of the series not to
be released on the Acorn Electron, the Electron
version was never released.
The game was then released by Nessprod for
iPhone and iPod Touch in 2009
