Tetra means FourThe name Tetris comes from the Greek work tetra or "four". Tetris is a computer puzzle game in which various shapes each made of four squares are falling down a well. The user turns the pieces around and moves them left or right in order to arrange them on top of the other. When a solid line of squares is made from edge to edge, the line dissolves and all the pieces move down by one square. When the lines dissolve points are won, when the well fills up the game ends. Players work hard to keep the well as empty as possible, but as the game progresses the pieces fall faster and faster making that harder.
