Gokuraku Jong Premium is an enhanced port of the mahjong puzzle game Gokuraku Jong which includes several new modes. Time Attack mode gives the player a 3-minute time limit to earn the highest score possible, Mission 16 mode gives the player 16 different mahjong hands to complete in a single play, and Yakuman Attack mode asks the player to get as many Yakuman (the highest-scoring Mahjong hands) as possible in a single game. It also adds in a new collectibles system, along with a handful of other tweaks.
