To commemorate the event of Puyo Puyo's 15th anniversary, Sega powered up their puzzle game and combined the previous installments of this series “Puyo Puyo”, “Puyo Puyo Tsu-” and “Puyo Puyo fever” in to one software.Puyo Puyo is a game where you line droplets of the same colored gems (puyo) together in a gap-less fashion. Although it is a simple game, it is a real challenge to master, especially with all the new battle modes. Some puyo puyo stages are flipped upside-down once every little while, some of them look as if they are filled with water so the puyo drops float on top, and these are just a few of the new fun stages designed specifically for the game.Aside from interesting stages, this 15th anniversary event is a large festival for the Puyo Puyo magical school, the characters from the first installment to the latest show up, ready to perform for the occasion. Puyo Puyo welcome new time gamers with innovative game play while old time gamers will find both a sense of familiarity and freshness in this installment.
