This is a straightforward Tetris game where players must complete lines by fitting variously shaped blocks into available spaces. The game concludes when the blocks reach the top of the board, obscuring any remaining lines.
Use the left and right arrow keys to move the pieces horizontally, the down arrow key to accelerate their descent, and the up arrow key to rotate the blocks. Alternatively, you can use on-screen buttons to perform these actions by tapping or clicking.
