Evaluation

Riichi City is a free-to-play competitive mahjong game that has been operating as a live service since its release on September 8, 2022. The game is built around a continuously rotating content cycle with no sign of slowing. Updates continue to arrive on a roughly biweekly schedule throughout 2026. Recent highlights include a Danganronpa collaboration event launched on July 10, 2026 (featuring four crossover characters and exclusive cosmetics), a new 4.5th anniversary character (Rukia) introduced on July 30, 2026 alongside a new limited-time game mode and multiple concurrent events, and another update on August 25, 2026 introducing additional character reruns, new gacha pools, and fresh cosmetic packs — with active events scheduled to run through September 30, 2026. The game's content model is built around monetized gacha pools, rotating limited-time characters and outfits, seasonal collaboration events, and ongoing gameplay additions. There is no indication from the developer that this content cycle will end.
