Puyo Puyo was released in October 1992 in Japan. Puyo Puyo is Japanese onomatopoeia for the sound that a rather plump person might make.
Puyo Puyo was originally released by Compile in 1991 for the MSX2 under the name "Puyo Puyo [Model IA-9106]
". It was soon followed by a version for the Nintendo Famicom Disk Drive called "Puyo Puyo [Famimaga Disk Vol. 5] [Model GTS-PYO]
" (featured characters from the 1989 RPG Madou Monogatari, also made by Compile). Puyo Puyo only really became popular when it was released as an arcade game in 1992. This was the first version that included a one player story mode, in which the human player plays against computer opponents of increasing difficulty. This feature was an immediate success because it allowed players to play by themselves. Future versions of Puyo Puyo for home systems also included this feature.
