Chuugokuryuu 2001 [Dragon World 2001]

Dragon World 2001 runs on IGS's PGM board and continues the Dragon World saga of tile games: despite an aesthetic reminiscent of mahjong, the mechanic is actually that of Shanghai solitaire, matching identical tiles to clear a layered stacked board, the same formula that circulated for years on any office computer.

It's representative of the tile-puzzle segment that IGS successfully exploited in Asia during the 2000s, a minor but constant genre within the region's arcade, meant for short, low-risk matches rather than the action spectacle that dominates the rest of the catalog.
