Tetris was invented exactly when and where you would expect — in a Soviet computer lab in 1984 — and its game play reflects this origin. The enemy in Tetris is not some identifiable villain (Donkey Kong, Mike Tyson, Carmen Sandiego) but a faceless, ceaseless, reasonless force that threatens constantly to overwhelm you, a churning production of blocks against which your only defense is a repetitive, meaningless sorting. It is bureaucracy in pure form, busywork with no aim or end, impossible to avoid or escape. And the game’s final insult is that it annihilates free will. Despite its obvious futility, somehow we can’t make ourselves stop rotating blocks.
