Tetris (テトリス) is a tile-matching puzzle game based around falling blocks. The name is derived from combining the Greek numerical prefix tetra- (the falling pieces contain 4 segments) and tennis.

Tetris was originally created by Alexey Pajitnov; he developed the first version of the game for Soviet Elektronika 60 terminal computers. Sega produced two arcade versions (a System 16 version and a System E version), a Mega Drive version, and a Mega Drive Mini version.

Gameplay

While the first version of Tetris (built for Russian Electronika 60 terminals) can be dated back to 1984, the first commercial versions of the game released in the West debuted in 1987, when Mirrorsoft (under license from Andromeda) began releasing the game for various home computer platforms. Sega's versions debuted in 1988, meaning they were amongst the earliest interpretations of the game.

As a result, the System 16 version of Tetris plays very similarly to 1984 Electronika 60 and 1986 IBM PC versions of the game, albeit with enhanced graphics and audio (which in this case, also means the addition of music). While licensed from Atari Games (who were not interested in publishing their own Tetris arcade game in Japan), the Sega versions share little in common with the Atari Games arcade version (also from 1988), with the two games having likely been developed independently with no knowledge of each others' progress.

The Sega versions of Tetris are played against backgrounds seemingly sourced from around the world depicting scenes of world evolution, in contrast to the earlier home computer versions which seeked to capitalise on Russian imagery (to the point where they are technically known as "TETЯIS" rather than "Tetris". As the player's level increases, the background changes, developing from the earliest known history of the Earth to a futuristic city. Also featured is a preview of the next Tetrimino, which is a feature carried from the Western computer versions.

The background changes as the player's level increases, depicting scenes of world evolution.

The Sega versions of Tetris are more "rigid" than later games, only allowing for pieces to be rotated if there is room (i.e. a piece is not "pushed" left or right if there is space to do so, and the player is not given the chance to rotate a piece shortly before it stops). More leeway is given to the player than the original Russian versions of the game, but the Sega versions are far less forgiving than their Atari Games/Tengen counterparts in the West.

Nevertheless, the ruleset, affectionately called Sega rotation became a fixture in Sega's other Tetris-inspired games during the late 1980s and 1990s, and became a de facto standard for Japanese Tetris games including Arika's Tetris: The Grand Master series (until The Tetris Company established official standards in the early 2000s).

The System 16 version of Tetris also includes a talking monkey which acts as a guide during the attract sequence. Monkeys would appear in later Sega-published Tetris titles as well. Also, while Tetris became would become synonymous with Russian folk songs (most notably, "Korobeiniki"), the Sega soundtrack is entirely original and to date has only appeared in Sega versions of Tetris. In addition, as the speed of the game increases, the the tempo of the main theme also gets faster.

History

Tetris was conceived by Alexey Pajitnov and he developed the first version for Elektronika 60 computers. Pajitnov ceded all the rights to Tetris to the Soviet government for a ten year period in 1986. Elorg, an organization owned by the Soviet government at the time, would be responsible for the licensing of any Tetris rights.

Sega of America representitive Steve Hanawa "discovered" Tetris on behalf of the company during the development of Monopoly. Hanawa noticed the Monopoly team working on a PC version of Tetris, and he became addicted to it after trying it out. Hanawa introduced Tetris to Sega of Japan, and the latter acquired the Japanese arcade and Mega Drive "rights" from Tengen. Tengen held what was believed to be the arcade and console rights at the time. The "rights" had passed through other companies before reaching Tengen; Tengen had been given the "rights" from their parent company, Atari Games, Atari Games licensed them from Mirrorsoft, and Mirrorsoft licensed them from Andromeda Software.

Andromeda's belief that they had the ability to sell any arcade and console rights to Tetris stemmed from a contract between them and Elorg (signed on May 10, 1988); the contract gave Andromeda the rights to Tetris for home computers and "different types of computers"; the phrase was vague enough for Andromeda to believe that it meant things like arcade systems and consoles.

Release

The System 16 version of Tetris was a hit in Japan, prompting additional versions of the game to be made for different arcade hardware - one for Sega's System E hardware, and two for Taito's B-System and H-System boards. The B-System versions were released as upgrade kits for Taito's Nastar and Master of Weapon; the H-System version appears to have been sold on modified boards that previously held Taito's Go for the Gold (released overseas as Recordbreaker) rather than as an upgrade kit. Although the arcade rights Sega received from Tengen were not legitimate at the time of their arcade versions' releases, those arcade versions would eventually be legitimatized after Andromeda signed a contract with Elorg on February 26, 1989 granting Andromeda the ability to sub-license arcade rights to Tetris legitimately.

Sega planned to release their Mega Drive version of Tetris on April 15, 1989, but they suddenly cancelled shipments of the title after they learned the Mega Drive "rights" they acquired were bogus. It is thought that fewer than 10 cartridges were produced, and some of the copies that survived were sold in auctions for up to US$16,000 (one signed copy was infamously sold for US$1,000,000,000). In an interview with Hiroyuki Miyazaki about the Mega Drive Mini, Miyazaki stated that he would have been fired if he had known what happened to the unreleased copies.

While Sega's arcade versions of Tetris could actually be legitimatized, their Mega Drive version could not - a second version of Elorg and Andromeda's computer contract (signed on February 23, 1989) had a definition of a computer added to it, and the Mega Drive version did not fit the new definition. In addition to the amended contract, a seperate contract between Elorg and Nintendo granted the latter all console rights. Despite all this, Sega was able to port the Mega Drive version over to their arcade-based Mega-Tech hardware.

Legacy

Atari Games, the company responsible for giving Sega the Japanese arcade rights through Tengen, stopped paying Mirrorsoft at some point. This resulted in Mirrorsoft not having enough money to pay Andromeda, and Andromeda not having enough money to pay Elorg. Because of this, Elorg decided to terminate their arcade rights deal with Andromeda in February 1992. The termination meant that Sega could no longer distribute their arcade versions of Tetris legally.

Sega's versions of Tetris introduced the concept of Sega rotation, which would influence many of the Tetris games made in the future. In addition to that, Sega's choice of music and aesthetics were adapted for the Sega Saturn game Tetris-S and the 1999 release of Sega Tetris.

Sega Ages 2500 Series Vol. 28: Tetris Collection, a licensed compilation of Tetris games for the PlayStation 2, includes the cancelled Mega Drive version of Tetris.

The Mega Drive Mini also includes this game. However, the version included on the system is not the original Mega Drive release, but a brand new version that is a more faithful recreation of the original System 16 version. This version was made under a license from The Tetris Company.
