Stacking Blocks description

Stacking Blocks are geometrically shaped games made up of four square blocks each. The random order of Tetriminos falls on the field (the vertical axis of the rectangle, called "good" or "matrix"). The object of the game is to manipulate the Tetriminos by moving each side to the side (if the player feels the need) and rotate it with a 90-degree unit, with the aim of creating a horizontal line of ten units without a gap.

Some games also end after a limited number of levels or lines.
