Tetris is the first Tetris game developed and released by Spectrum HoloByte, and the first version to be released commercially.

There are two versions of the game; the revised version has the plane on the title screen removed (at the request of Elorg) and the military-themed backgrounds replaced (at the request of Pajitnov). The revised version was also featured on Tetris Gold.

Timing

This section needs expansion. You can help TetrisWiki by expanding it.

Timing is based on video frames, which are approximately 1/70 of a second.

Scoring

Level Select screen

Placing a piece awards score according to the following formula:

  • points = 4 + (2 * level) + row number of top of piece

The bottom row is number 1. If the piece was dropped manually, the position before dropping is used, so for a high score the player should drop as soon as possible.

If piece preview is enabled at the time a piece is placed, a 25% penalty is assessed: (both divisions are rounded down)

  • points with preview on = floor(points / 2) + floor(points / 4)

No additional points are awarded for line clears.
