KI is a mixture of Klax (or KlakTris) and Ishido: Tiles are dropping and
squares vanish, if some equal are in a row, but the squares are not
only of different with colours, they also have different kinds.
KI is widely configurable, you may e.g. paint your own squares.
It's localized, currently only english and german (deutsch).
