This is a straightforward block-based Tetris game where the player must complete horizontal lines by fitting variously shaped pieces into empty spaces. The game concludes when the incomplete lines reach the top of the playing field.
Controls include the left and right arrow keys to move the blocks sideways, the down arrow key to accelerate their descent, and the up arrow key to rotate the pieces. Alternatively, you can use on-screen buttons to perform these actions by tapping or clicking.
