In Clickenzee you are presented with a screen full of various types of
squares. The objective is to clear the screen, which is done by removing
groups of 2 or more identical adjacent squares. These are removed, with those
which were above them falling down. Empty columns also slide along to the
left. Each time scores points for the number of tiles you remove with that
move.

The tactic is therefore to avoid leaving a single square of a particular
design isolated from the others. A minimum victory points target is assigned –
beyond that, you get a bonus for each percent of the screen that is cleared.
Targets are cumulative, so that comfortable success on one level will make
your task easier on the next one.

There are five bonus titles, distributed randomly though the levels. Two of
these rotate the blocks (horizontally or vertically), producing a random one
in place of the tile, while the other three change all tiles in a row, column
or block at random. Note that these are the only moves which can’t be undone.

There are four different sets of tile patterns.
