1. Tetris Was Created In The Soviet Union

Alexey Pajitnov designed Tetris in 1984 on a clunky Soviet Elektronika 60 with no graphics, just text. Square brackets became falling blocks. He didn't see a dime until 1996—twelve years later—because the Soviet government owned all intellectual property.

5. The Blocks Are Called "Tetrominoes"

Each of Tetris' seven shapes—like II, O, T, S, Z, J, and L—is made of four linked squares, making them tetrominoes. The term comes from geometry, not gaming. This exact set fits perfectly into a 10x20 grid, and no other combination does.
