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


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.
