Tetris — Play Free Online

Retro & Pixel

Tetris is the ultimate block-stacking puzzle classic: rotate falling tetrominoes to clear horizontal lines and keep the matrix from topping out.

About Tetris

Tetris by Alexey Pajitnov remains the undisputed king of puzzle games. As seven distinct geometric tetrominoes descend from above, rotate and slide them into complete horizontal rows. Each filled line dissolves, keeping your matrix clean as gravity accelerates with every level cleared.

Pure, elegant logic that is effortless to learn yet impossible to put down.

How to Play Tetris

  1. Rotate and maneuver falling tetromino shapes into solid horizontal rows.
  2. Clear multiple lines simultaneously—a four-line clear is a coveted 'Tetris'.
  3. Keep the stack below the skyline to avoid topping out.

Controls

  • Left/Right arrows: Move piece horizontally.
  • Up arrow: Rotate piece clockwise.
  • Down arrow: Soft drop; Spacebar: Hard drop.
  • C or Shift: Hold piece for later use.

Tips and Tricks

  • Keep your stack relatively flat to avoid creating deep vertical pits you cannot fill.
  • Leave the far right column open for the long 4-line I-piece to score massive Tetris bonuses.
  • Use the Hold box strategically to save key pieces for sticky situations.
