Emeraldia
翠玉
Emeraldia is an action puzzle game released by Namco in 1993 for arcades. Players control a character who must arrange and match falling gem-shaped blocks to clear the playfield, combining action mechanics with puzzle-style chain reactions. The game features a vertical playing field where colored emerald blocks drop from above, and players must position them to create matches and trigger combos. Controls are straightforward, using a joystick to move and buttons to rotate or drop pieces. Emeraldia includes a versus mode where two players compete side by side, attempting to outpace each other by clearing blocks faster and sending interference to the opponent's field. The game progresses through escalating difficulty as block drop speed increases.
