Play Double Yakuman (Japan) Online
The AI actually plays smart in this no-frills mahjong game—you’ll sweat when they start hoarding tiles just as you’re about to hit a yakuman. Those tiny Game Boy controls make slapping down tiles weirdly satisfying.

Double Yakuman came out for the Game Boy in 1991, developed by I'Max. It was one of the few dedicated mahjong titles on the system, offering a straightforward take on the traditional Japanese tile game during a time when portable gaming was still mostly about action and adventure.
You play against one to three computer opponents, aiming to form specific winning hands by drawing and discarding tiles. The game includes standard riichi mahjong rules, with mechanics like calling pon or chi to complete sets, and the ability to declare riichi when one tile away from winning. Matches move at a deliberate pace, and the AI can be surprisingly sharp, especially at higher difficulty levels. It feels focused and tense, especially when you're trying to build a high scoring hand while watching what the others are collecting.
