You think you know Tetris. Falling blocks, line clears, gets faster — every developer alive has played it. But Tetris has a published 60-page specification called the Tetris Guideline that defines an eight-phase state machine, a 7-bag randomizer, a Super Rotation System with wall-kick offsets, T-spin detection, and three different placement-time rules. There's a 40-year competitive community, a licensing saga that became an Apple TV movie, and a teenager who in late 2023 became the first human to play far enough into NES Tetris to crash it. I built my own Tetris in PHP from the spec. This talk is what falling blocks taught me about specifications, state machines, bitmask encodings, and the strange power of communities that outlive the products that birthed them.
