Tsumo Dragon: Riichi Mahjong

Practice riichi mahjong at your own pace. Tsumo Dragon is a solo Japanese mahjong game where you draw a tile, read your hand, and choose a discard. See shanten and effective tiles as you work toward tenpai—a ready hand—and a winning draw.

No opponents or matchmaking to wait for. Replay the first six Dragon Gate Trials free, then explore more challenges with a one-time full-game purchase. No ads or subscription.

NEW: DRAGON GATE TRIALS
Explore four gates and 24 handcrafted challenges. Reach tenpai (a ready hand) or win within each trial's turn limit to advance. Clear the main objective, then pursue the extra Divine Discard and RUSH conditions for up to three Dragon Seals.
Each trial uses a fixed tile wall. Replay it, try another discard, and improve your best result. Trial progress is saved separately from Classic mode.

START FREE
The first gate's six trials are free to replay. You can also try your first 10 Classic games free. One full-game purchase unlocks access to the remaining gates and unlimited Classic play. Trials open in order as you clear them. Existing full-game owners receive the new trials at no extra charge.
