About Tetris (1987 DOS Version)

Tetris is the timeless puzzle game where geometric shapes — called Tetrominoes — fall from the top of the screen. The goal is to rotate and stack them to complete horizontal lines, which then clear for points.

Gameplay Rules

• Move and rotate falling blocks to fit them together.
• Complete horizontal lines to clear them and earn points.
• Game speed increases as you clear more lines.
• The game ends when the stack reaches the top of the screen.
