Yakuman

Yakuman is a digital tabletop Japanese mahjong game for Game Boy, released in 1989 as one of the system's launch titles in Japan only. Gameplay features single-player mode against five computer-controlled opponents and two-player versus mode requiring Game Link Cable; players draw and discard tiles from a 14-tile hand to form melds, declare tenpai or mahjong, and score points under various rule variations including yakuman hands. The story involves classic mahjong competition with no narrative characters, but the game highlights the iconic yakuman (32,000-point rare winning hands). It stands out as the first Game Boy title to implement the Game Link Cable for multiplayer, pioneering portable competitive play and becoming a legacy mahjong series entry.
