Puyo Puyo! 20th Anniversary

Puyo Puyo 20th Anniversary is an installment in the Puyo Puyo series. Gameplay-wise, the basic elements of Puyo Puyo are still there - eliminate Puyos and bury your opponents in a landslide of Nuisance Puyos. But in addition to the standard "Puyo Puyo", "TSU" and "Fever" rules, there are also new gimmick modes and modes returning from past Puyo Puyo games. The most noticeable rule change in the game, however, may be the "Pair Puyo" mode, a co-op mode where two teams of two players battle it out to end all their opponents' lives.
