Just the Basics
Using the arrow keys, you can adjust where and how the Tetriminos fall. By pressing the LEFT and RIGHT Arrow keys, you can slide the falling Tetrimino from side to side. You can’t slide a Tetrimino past the edge of the Matrix. By pressing the UP Arrow key, you can rotate the Tetrimino 90 degrees clockwise. You can move the Tetriminos even after they land at the bottom of the Matrix briefly. The Tetrimino will Lock Down as soon as you stop trying to move it. At that point, the next Tetrimino will begin to fall.
