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 DOS release; 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 other Spectrum Holobyte versions were based on the revised version.

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.

Development

Under the presumption that a proper license to Tetris had been secured, Robert Stein began shopping the title around to various publishers. One notable publisher to pass on this option was Broderbund.[1][2] Ultimately, the rights to produce Tetris for home computers were licensed to Mirrorsoft in Europe and its sister company Spectrum HoloByte in America. As Spectrum HoloByte had also merged with Gilman Louie's development company Nexa Corporation (under a holding company Sphere Inc.), development was carried out by staff and contractors of all three related companies.

The DOS version was developed in 8086 assembly at the Nexa office in San Francisco, CA. The Amiga and Atari ST versions was initially assigned to John Jones-Steele, who programmed the conversions of Mirrorsoft's Tetris for the same platforms previously. However, the initial approach of auto-converting the original 8086 code to 68000 code had issues with poor performance and other bugs. As such, Nexa programmers Kevin Seghetti and Gary Poon took over the Amiga and Atari ST projects to clean them up for release.[3][4]

The Apple II and Macintosh versions were handled by Spectrum HoloByte, and were written from scratch. The Macintosh version was contracted to Roland Gustafsson, who had previous experience programming his own fan game "Quadris" after playing a copy of Vadim Gerasimov's port of Tetris that was sent to Broderbund for consideration for licensing.[5][6]

As a result of the contract disputes over the rights to Tetris, Robert Stein ultimately lost any rights to produce home computer versions of Tetris. As a result, Spectrum HoloByte entered into a contract directly with Elorg in order to legitimize their license to produce their version of the game, as well as future sequels such as Super Tetris and Tetris Classic.[7]
