Tetris is one of the oldest games, and we have it in video game form! If you don't know what Tetris is, the objective is to complete as many rows as possible using the shapes.
In the video game version, use your arrow keys to adjust the direction the shape is facing. Use the up arrow key to rotate the shapes. You can use the left and right arrow keys to move the shape left and right. In order to make the shape fall faster, press the down arrow key.
Once you complete a row, you will get score. You also get score every time you place a piece. There are different levels to complete as well.
