Puyo Puyo SUN (ぷよぷよSUN , Puyopuyo San ) is the third installment of the Puyo Puyo games series, and the sequel to Puyo Puyo Tsu, made in 1996 by Compile.
 After the highly acclaimed success of its predecessor, Compile took a slightly more retro approach, so players had a more original feel to the game over that of Tsu.
Puyo Puyo BOX is a compilation video game developed by Compile for the Sony PlayStation.
 It is Compile's last recognised "Puyo Puyo" title in the series before Sega, previously only owning the character rights, fully obtained the rights to the series.
 "Puyo Puyo BOX", being a compilation, primarily consists of earlier "Puyo Puyo" games, but also contains original content.
Puyo Puyo!
 15th Anniversary (ぷよぷよ!
 , Puyopuyo! )
 is a sub-story of the Puyo Puyo series, developed by Sonic Team and published by Sega for the Nintendo DS, PlayStation 2, PlayStation Portable, and Wii.
 As with many other games in the series, it has not been released outside Japan for any consoles.
 This is the first Puyo Puyo game to be released on the Wii console.
 The game was endorsed by Yuri Ebihara.
Puyo Puyo (ぷよぷよ , Puyo Puyo ) is a puzzle video game released in 1991 by Compile for the MSX2.
 Since its creation, it uses characters from "Madou Monogatari".
 It was created by Masamitsu "Moo" Niitani, the founder of Compile, who was inspired by certain elements from the "Tetris" and "Dr. Mario" series of games.
Tetris (Russian: Те́трис , pronounced ] ) is a tile-matching puzzle video game, originally designed and programmed by Russian game designer Alexey Pajitnov.
 It was released on June 6, 1984, while he was working for the Dorodnitsyn Computing Centre of the Academy of Science of the USSR in Moscow.
 He derived its name from the Greek numerical prefix "tetra-" (all of the game's pieces contain four segments) and tennis, Pajitnov's favorite sport.
Puyo Puyo Tsu (ぷよぷよ通 , Puyo Puyo Tsū , also known as "Puyo Puyo 2", "Puyo Puyo Tsuu" or "Puyo Puyo 2: Tsuu") is the second installment of the "Puyo Puyo" games; the sequel to "Puyo Puyo", made in 1994 by Compile.
 Compile put more thought into this game after its predecessor became successful, but never knew how much of a turnaround the game would bring.
Puyo Puyo (ぷよぷよ), previously marketed under the name Puyo Pop in North America and Europe, is a series of tile-matching video games created by Compile.
 Sega has owned the franchise since 1998, with most releases after 2001 being developed by Sonic Team.
 Puyo Puyo was created as a spin off franchise to "Madou Monogatari" ("Story of Sorcery"), a series of first-person dungeon crawler RPGs by Compile.
 The characters from "Puyo Puyo" originated from "Madou Monogatari".
 As of 2016, Sega Sammy Holdings has reported that the "Puyo Puyo" franchise has sold a combined total of 22 million units in physical and digital sales since Sega obtained the rights.
Puyo Puyo~n (ぷよぷよ〜ん , Puyopuyōn ) , also known as Puyo Puyo 4, and Puyo Puyo~n Party (for the N64 version) is the fourth installment of the Puyo Puyo puzzle game series, created by Sega and Compile for the Sega Dreamcast, Sony PlayStation, Nintendo 64 and Game Boy Color.
 Like many of the Puyo Puyo games, it was never officially released outside Japan.
 The title of "Puyo Puyo~n" comes from the Japanese word "yon" (四 , meaning four) , signifying the fourth game in the series.
 Plans were made for a 64DD version entitled Puyo Puyo~n 64 (ぷよぷよ〜ん , Puyopuyōn rokujuon ) , but it was later cancelled.
Puyo Pop, known as Minna de Puyo Puyo (みんなでぷよぷよ , "Everybody Puyo Puyo") in Japan, is the first of the Puyo Puyo games made for the Game Boy Advance, and the first produced by Sonic Team after Compile went bankrupt and sold the rights to Sega.
 However, at the same time, it is the last to use the original Madou Monogatari cast.
 It was not counted in the "official" sequence, nor were the later "Anniversary" games, as evidenced by the naming of Puyo Puyo 7.
Puyo Puyo 7 (ぷよぷよ7 , Puyo Puyo Sebun ) is the seventh installment in the Puyo Puyo series released in Japan for the Nintendo DS on July 30, 2009, and for the PlayStation Portable and Wii on November 26, 2009 .
 This game is endorsed by Erika Toda, following on from Sega's use of female Japanese stars to promote the series.
