Medal City is a gambling compilation game that debuted on Game Toshokan, available via the Sega Meganet service. It offers players the chance to play three casino games: Poker, Blackjack, and Slots. The game was later included in the compilations Game no Kanzume Vol. 2 for Sega CD and Game no Kanzume Otokuyou for Mega Drive.
The player can choose to leave any of the three games with their winnings and attempt a different activity. Their medal count, which needs to reach 100,000 before the player "wins" the game, carries over from game to game. The game ends once the player has lost all their medals.
