The idea of the game is to fill one or more horizontal line with
the falling pieces. Do it as quickly as possible to get the highest
The pieces fall freely from the top of the pit, until they hit
another piece or the bottom of the pit, as in tetris. However,
should the piece hit a block of its own color, this block will
crumble, and the piece continues to fall until it hits the bottom
of the pit, or blocks of a different color. When it has landed,
the current points will be added to your score and a new piece will
appear at the top of the screen.
Every 60 pieces the game speed is increased and the piece points are doubled. The point value of the current piece is shown at the "Curr. points" line.
