What Tetris is
Tetris is one of the best-known puzzle games: pieces (officially called Tetriminos) fall continuously, and players rotate and arrange them so completed lines clear for points. The official site, tetris.com, calls it “one of the most iconic and beloved video games in history,” credits “Tetris Game Design by Alexey Pajitnov,” and notes the game was created in 1984. The trademark and copyright belong to Tetris Holding, licensed to The Tetris Company.
Gameplay and official versions
The core rule is clearing lines: the falling shapes are limited, the player decides where they land, a filled line disappears, and a stack reaching the top ends the game. Implementations and modes have varied for decades, but this core has stayed stable.

Mention in the show
In Weekly #003’s chapter ““没有幻觉”不等于判断正确” (the “no hallucination” chapter of the Chinese transcript), while discussing what a newly released small model is good at, Orange says one of the model’s most valuable applications is Tetris — using real-time probabilities to pick pieces, it “played 66 lines without dying”. The subject there is the model’s ability to convert a limited set of options into real-time decisions, with Tetris as the example task.
