Tetris has an ending?!

Russian space ships taking off! No joke. Your ending score would dictate the type of ship that takes off.

A minimum of 30 thousand points is required to unlock the end scene.

Two game types exist, A mode and B mode.
For A mode, it has 3 points classes, all of which are different Soviet Union rockets.

for B mode, towns people can be seen dancing and playing instruments which than cuts to a full on space shuttle being launched.

The game is essentially you helping the Soviet Union win the space race, Back when that was a thing.
