How do you beat the computer on Tetris?

To beat the computer in Tetris, focus on maintaining a clean and organized stack, prioritizing flat surfaces to maximize piece placements. Aim to create Tetrises (clearing four lines at once) by setting up combos and keeping an eye on upcoming tetrominoes. Utilize hard drops for quick placements and minimize gaps to prevent the stack from rising too high. Finally, practice quick decision-making to efficiently manage pieces and adapt to changing game conditions.
