Given the vast number of clones and legal grey areas, pin-pointing an exact figure for the number of Tetris variants is a tricky process. However, as of 1 February 2017, the Tetris Company revealed that there had been approximately 220 licenced and official variants of Alexey Pajitnov’s classic puzzler, ranging from the 1989 Game Boy classic to Pokemon Shock Tetris (2002) and the multiplayer Tetris Party (2008), and including numerous online variations and territorial mobile games. Although many games on the list have the same name as Tetris, they all have unique variables, such as different music and background images.
