Tetris is one of the oldest, most enduring, and most accessible video games out there. It is easy to understand, never ends until you fail, and players slowly get better at it as they play, leading to a thrilling gameplay loop that can keep gamers hooked for hundreds of hours despite the simple concept. The story around its creation is also interesting, coming from the Soviet Union with its creator, Alexey Pajitnov, being locked out of royalties for years as it slowly came to the West on consoles like the Game Boy and NES through a tangled web of legal and distribution rights.
