That's Mahjong!

That's Mahjong! launched on October 27, 2016 and received a handful of updates through May 18, 2017 — a Halloween patch, a Winter Update adding new themes, and a small May 2017 patch that added Steam Cloud. No further content updates followed after May 2017. On October 25, 2025, the solo developer published an important announcement explaining the long silence. They described a difficult series of personal events beginning in 2018–2019 that halted development, the loss of source code files containing unfinished work, and their decision to keep the game on Steam out of sentimental attachment. Critically, they stated they are no longer planning to update this game further — instead, they intend to release a separate sequel, That's Mahjong 2, at some point in the future. The October 2025 post included only a minor cloud-sync patch, not a content update. The store description still references planned features like Steam Leaderboards and future themes, but those statements predate the developer's own acknowledgment that active development on this game has effectively ended. The developer's October 2025 statement makes clear that this game is considered finished in its current form, with any future work redirected to a new title entirely. The game can be considered content-complete as of the last meaningful update on May 18, 2017.
