Hi all, I've been trying to do a bit of definitive research regarding the specific terminology of the "Tetris pieces" within licensed Tetris games. Here's what I know so far: - They were called "Tetrads" (with first letter capital) in a Nintendo Power magazine article about Nintendo NES Tetris in 1989 (see the scans Edo posted here). - They were inconsistently called "Pieces", "blocks", "Falling Blocks", etc. in a bunch of games pre-1999. - 2001's Tetris Worlds first used the "Tetrimino" term (along with all of its sci-fi backstory e.g. Minos are a species found on the planet Hadar 4, Tetrions are Gateways to planets orbiting distant stars, etc.) Here's what I want to find out: - 1999's The Next Tetris was released while TTC's internal Guidelines were a work in progress (then called "What is Tetris?). Did they use the term "tetramino" for this title as the wiki suggests? I can't find any proper instruction manual scans online. The New Tetris (also 1999) just called them "variously shaped pieces". - Did any of the earlier licensed games have any such distinctive terminology in their instructions? Do any licensed games ever actually refer to them specifically as "tetromino"?
