Puyo Puyo 2

}}

Puyo Puyo 2 (ぷよぷよ通; Puyo Puyo Tsū) 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. Due to its highly acclaimed success, it became the most predominant game of the series. Though with many of its rules being experimental, the ability of Sousai (相殺, sōsai, the damage offset rule) and Rensa Sibari (連鎖縛り, rensa shibari, a custom rule that causes chains with fewer than a set number of steps to score nothing and to send no garbage) became a top hit immediately, thus creating longer matches for better gameplay. Also due to its successes, it became the most widely known multiplatform game in Japan, appearing in the Arcade, on major domestic consoles, on major handhelds, on the NEC PC-9800 series, on the PC, and on others.

The name of Puyo Puyo 2/Tsū derives from an English pun, as "tsu" (通, tsū, meaning Expert) when spoken aloud sounds similar to the English word "two". Compile used similar puns for Puyo Puyo SUN and Puyo Puyo~n.

Puyo Puyo 2 was originally developed by Compile and released by Sega for arcades in 1994, and became the biggest arcade game to have been played in Japan since the arrival of Street Fighter II. The success of the game prompted Compile to port the game to several consoles and computers, including the Super Famicom, Mega Drive, PC Engine, Game Boy, Master System, Game Gear, Sega Saturn, PlayStation, PC under Windows 95, WonderSwan, Neo Geo Pocket Color, PlayStation 2, Xbox, et al. The game Puyo Pop is also heavily based on this particular installment of the series, a Virtual Boy port was in development, but never released due to the system's failure. In addition, a Game.com port was planned, but was cancelled in favor of a Game.com port of Puyo Puyo Sun. Versions for Atari Jaguar and 3DO Interactive Multiplayer were also in development, but were cancelled for unknown reasons.

The Super Famicom version added a 4-player mode - Compile's first attempt at such a mode for a domestic console - with the use of a multitap. Without a multitap, 3 and 4 MAN players cannot be played. Months later, Compile released Super Puyo Puyo 2 Remix (す〜ぱ〜ぷよぷよ通リミックス), a special version of the Super Famicom game that allowed up to 4 players to play without the need of the multitap, by replacing the human players with computer ones. A port was also released for the PC Engine (in Super CD-ROM² format) titled Puyo Puyo CD 2 (ぷよぷよCD通). Super Puyo Puyo 2 Remix also included two new Extended Training and Special Modes, as well as other features. Another case are the PC-Engine CD, Saturn and PlayStation versions, which add voice-overs and cutscenes. The PC version of Puyo Puyo 2 was the only version to include a separate Nazo Puyo quest, as the CD versions had a "cut-down" version included into them. To show the success of Puyo Puyo 2, in the Sega Ages 2500 series for the PlayStation 2, Sega released a version titled Sega Ages 2500 series Vol. 12: Puyo Puyo 2 PERFECT SET (セガエイジズ2500シリーズ Vol.12 ぷよぷよ通パーフェクトセット), which paid tribute to one of the most popular versions, the Sega Saturn version. It was also ported to the Xbox, but was not released in Japan. A large number of versions of Puyo Puyo 2 were internationally released, though released through various publishers. Making this the thrid in the series to have a Western release after Dr. Robotnik's Mean Bean Machine and Kirby's Ghost Trap/Avalanche.

For the first time, the arcade version of Puyo Puyo 2 finally saw a western release on April 26, 2016 by developer M2 for the Nintendo 3DS as a part of the Sega 3D Classics Collection game pack after nearly twelve years of being exclusive to Asia. The game itself remained untranslated.

In 2019, Sega announced the Arcade version will be re-released for the Nintendo Switch under the Sega Ages Puyo Puyo 2 (SEGA AGES ぷよぷよ通) brand.

The Super Famicom version was released on SNES and Super Famicom Nintendo Switch Online.
