Mahjong Reach Ippatsu

Mahjong Reach Ippatsu (麻雀立直一発) is an extremely rare Japanese mahjong arcade game developed and released by Dynax in 1998.

The game is categorized as a "bet-type" adult arcade machine (often featuring stylized anime/gekiga characters) that features traditional Riichi Mahjong rules. In Japanese Mahjong, "Reach" (Riichi) and "Ippatsu" (One-Shot) are specific winning scoring conditions (yaku).
