Puyo Puyo!! 20th Anniversary

It is the second anniversary game of the series and therefore has more similarities with "Puyo Puyo! 15th Anniversary" than with "Puyo Puyo 7". This game came out 4 months before "Sonic Generations", which also celebrates the 20th anniversary of the Sonic games. There are 24 playable characters, each with their own 8-stage course (similar to Puyo Puyo! 15th Anniversary). This game, like its predecessor, was only released in Japan.
