Tetris

Tetris is a puzzle video game created in 1985 by Alexey Pajitnov, a Soviet software engineer.^[1] It has been published by several companies for multiple platforms, most prominently during a dispute over the appropriation of the rights in the late 1980s. After a significant period of publication by Nintendo, the rights reverted to Pajitnov in 1996, who co-founded the Tetris Company with Henk Rogers to manage licensing.
