How it plays

How does Tetris play?

The playfield is viewed from the side. Random tetrominoes fall from the top, and the player moves or rotates each piece to form complete horizontal lines without leaving unusable gaps.

Completed lines disappear and award progress, while the remaining blocks settle downward. The game becomes more demanding as pieces fall faster; play ends when the stack reaches the top. DOS editions may differ in scoring, preview displays, starting levels, pause behavior, and available two-player or campaign-style modes.

Plan your run

What is the best way to play Tetris?

Keep the stack low and build a fairly even surface rather than creating isolated towers. Reserve one vertical column when possible so a long bar can clear four lines at once.

Avoid covering holes that cannot be reached by later pieces. As the speed increases, prioritize safe placement over ambitious setups, and use a pause only if the particular DOS edition documents one.

Before you begin

What should you know before playing?

  1. 1

    Plan the landing position before the piece reaches the bottom.

  2. 2

    Clear lines regularly to prevent the stack from becoming too high.

  3. 3

    Treat the long bar as a valuable tool, but do not depend on receiving it.
