Jantaku Boy — About this game
Jantaku Boy presents four-seat Japanese mahjong with both a solo ladder and a free half-game against computer opponents. The ladder demands first place to advance through four rounds, with passwords preserving progress between victories. A separate rules screen changes options such as open tanyao and redrawn-hand behavior. Linked modes let human players share the table while computers fill empty seats, making hand selection and calls part of the same readable tile display.
Begin with Free Play, select a tile with the pad and press A to discard. Up/left/down also select pon/chi/kan, while B claims a win and up+A declares riichi. SELECT displays scores on your turn; hold START with the pad to inspect the table during your draw.
