The playfield is the grid into which tetrominoes fall, also called the "well" (common in older games) or the "matrix" (especially in more recent Tetris brand games). The playfield is surrounded by a frame called the tetrion, which controls the overall behavior of tetrominoes.
The vast majority of tetromino based game use a playfield 10 blocks wide and between 16 and 24 blocks tall. Notable exceptions are the following:
- Abandoned Bricks: 9 w
- Gnometris: 11 w
- Tetrinet: 12 w
- Tetris Jr.: 8 w
- Tetris Wristwatch: 6 w
- Tetripz: 11 w
Columns are conventionally numbered from left to right, and rows from bottom to top.
The Tetris Guideline specifies a playfield 10 blocks wide by at least 22 blocks tall, where the tetrominoes are started in rows 21 and 22. Some games hide rows 21 and up.
