In some tetris games the ceiling can prevent a piece from rotating. It's common that these games lack wall kicks as well. Classic games with these rules include Tetris (IBM PC) and Tetris (Sega).

Modern games do not have this restriction.

In many SRS games the pieces actually spawn above the ceiling.
