Play Jantaku Boy Online

Jantaku Boy is a 1994 Game Boy release from Naxat Soft, a title that arrived late in the handheld's life when puzzle games were a crowded but reliable genre. It stands out not by reinventing mahjong but by wrapping it in a competitive, almost aggressive single-player structure, a stark contrast to the more placid solitaire experiences available at the time.

You control a cursor to select and discard tiles against one to three computer opponents. The main objective is to win rounds by completing a valid hand before your rivals can, with the ultimate goal of climbing the ranks in the tournament-style Kachinukisen mode. Its signature mechanics include a high-stakes, sudden death rule where losing four consecutive rounds results in an immediate game over, and a two-player versus mode that requires a link cable and another cartridge. The pacing is deliberately tense; the AI makes strong, fast decisions that pressure you into mistakes. Playing it feels like being in a back-alley game where every tile matters.
