For example, the distribution of tetrominoes was completely randomized in early versions, while modern versions opt for a "bag system", in which each tetromino is guaranteed to appear in a set of seven.{{sfn|Plank|2022|pp=271–272}}{{sfn|Pajitnov|Rogers|2023|loc=6:19–6:48}} Other mechanics that have become standardized in modern versions include the ability to hold tetrominoes to swap with later pieces, introduced in ''[[The New Tetris]]'' (1999),{{sfn|Linneman|2018|loc=31:24–31:34}} and the super rotation system and infinite spin, introduced in ''[[Tetris Worlds]]'' (2001).{{sfn|Linneman|2018|loc=37:42–38:07}}

The earliest versions of ''Tetris'' had no music.{{sfn|Pajitnov|Rogers|2023|loc=3:10}} Spectrum Holobyte's version of ''Tetris'' in the United States exoticized the Soviet origins through elements such as Russian music, including [[Pyotr Ilyich Tchaikovsky]]'s "[[Trepak (The Nutcracker)|Trepak]]" from ''[[The Nutcracker]]'' and [[Reinhold Glière]]'s "[[Russian Sailor Dance]]" from ''[[The Red Poppy]]''. This approached differed from other versions of ''Tetris'' from other countries at the time: Mirrorsoft's Commodore 64 version in Europe used an atmospheric soundtrack, and Sega's arcade version in Japan used a synthesized pop-influenced soundtrack.<ref name=soundtrack>{{cite journal |url=https://intellectdiscover.com/content/journals/10.1386/st.8.1-2.7_1 |last=Plank-Blasko |first=Dana |title='From Russia with Fun!': Tetris, Korobeiniki and the Ludic Soviet |journal=The Soundtrack |volume=8 |issue=1–2 |date=October 2015 |pages=7–24 |doi=10.1386/st.8.1-2.7_1 |access-date=November 15, 2024 |archive-date=July 10, 2024 |archive-url=https://web.archive.org/web/20240710081002/https://intellectdiscover.com/content/journals/10.1386/st.8.1-2.7_1 |url-status=live |url-access=subscription }}</ref> Nintendo's versions for NES and Game Boy continued the pattern of using Russian music.
