Tile Tempo: Riichi Mahjong

Tile Tempo is portrait-first, offline riichi mahjong built for players who want to open the app and start playing immediately. No matchmaking. No account. No waiting for another player to discard. The AI rivals are trained from a large-scale mahjong decision model, run locally on your device without a network connection, and play using only their own concealed hands and public table information. Choose the difficulty that suits you. THREE WAYS TO PLAY • Ranked: Play East games, build rank points, meet varied rivals, and climb through the rooms. • Tournament: Enter a local 16-player bracket. Finish in the top two to advance through hanchan semifinals and the final. • Custom Table: Choose East-only or hanchan, set the difficulty, select rivals, and configure your table. PLAY ANYTIME Every committed action is saved automatically. Leave in the middle of a hand and return to the exact same table later. Core gameplay works offline and never requires an account.
