The goal of the game is to complete a layer with blocks without gap
which will cause the layer to disappear. With ongoing time this will
become more and more difficult as the speed with wich the blocks fall
will increase. After you achieved to complete 5 layers, the game level
and hence the speed gets raised by one but by the same time the scoring
per completed layer gets raised too. The scores are calculated from the
number of blocks the number of completed layers and the game level. The
game ends when your building touches the ceiling so that no more blocks
can fall in. At the end of the game you get the opportunity to put your
name on the » highscore list.
