Dropping down a piece using the Down Arrow gives a small number of points which is equal to the drop height. It is not much each time but is particularly relevant in the earlier levels, when the pieces fall more slowly.

The biggest part of the score comes from destroying full lines. It is very important to note that destroying multiple lines at the same time gives you a lot more points. A four-lines destruction is called a “tetris”: it gives a maximum amount of points.

The points gained are 40 for a one-liner, 100 for two lines, 300 for three lines and 1200 for a tetris. These numbers are multiplied by the current level. For example, destroying four lines in level 10 gives 12,000 points.
