Revisional Differences

When info about this version made its way to the Russians they demanded a few changes to the game.

Title Screen

In the original version of the game, a plane flies across the title screen before the opening scroll, a reference to Mathias Rust and his flight over Red Square. The incident was considered a national embarrassment to the Russians, and Elorg demanded that the plane be removed as a result. The copyright text was also made slightly thicker and takes up a bit more screen estate in the revised version.

Version 1.0	Revised version

After the opening scroll is the Play Tetris screen. In the original version the plane returns with a banner reading "Play Tetris!", and the player must press a key to move on to the programmer credits. In the revised version the Play Tetris screen disappears almost instantly, presumably just before the plane would appear.

Version 1.0	Revised version

Level Select Screen

The level select screen has different colours. Why this was changed is unclear.

Version 1.0	Revised version

Stage Backgrounds

Backgrounds depicting submarines and fighter planes were replaced because Pajitnov wanted Tetris to be "a peaceful game heralding a new era in the relationship between superpowers and their attitude toward world peace."

Version 1.0	Revised version

Level 3, containing submarines, was changed to a man riding a horse.

Version 1.0	Revised version

Level 8, containing fighter planes, was changed to a theatre performance.
