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.
