Tetris was created in 1984 by Alexey Pajitnov and became one of the most widely played puzzle games in the world, with its falling blocks and simple rules translating easily to small screens. Inexpensive handheld brick game consoles later made that same gameplay portable and familiar to a generation of players, even when the devices did not use the Tetris name. The start-up sound became shorthand for retro gaming itself, and it still appears in nostalgia edits, challenge videos and game compilations because listeners recognise the melody instantly.
