Pro Mahjong Tsuwamono ("Pro Mahjong Soldier") is the first game in Culture Brain's long-running Pro Mahjong Tsuwamono series, which lets players take on various big figures in the world of professional mahjong. While this first game is a Super Famicom exclusive, subsequent games would be released on other systems, including the PlayStation, Nintendo 64 and Game Boy Advance. Tsuwamono offers a traditional, no-frills, single-player mahjong game against three CPU opponents. The game uses digitized portraits for its licensed pro players, all of whom emote after wins and losses.
