This is a straightforward Tetris-style game where players must complete horizontal lines by fitting variously shaped blocks into the empty spaces. The game ends when the stacked blocks reach the top of the playing field.
Use the left and right arrow keys to move the blocks horizontally, and press the down arrow to accelerate their descent. To rotate the tiles, press the up arrow key. Alternatively, you can tap or click on the on-screen buttons to perform these actions.
