Play. Get stuck.Ask the AI.Get stronger.
Mahjong Q'z is a mahjong app where you learn through games against AI, practice quizzes and lessons. When you're stuck, Aria, a strong mahjong AI, shows you the candidates and the reasons behind them.
Train exactly the spots you struggle with.
Practice Quiz uses real positions taken from games between strong AIs. Pick the round, dealer or non-dealer, your placement, the turn and what your opponents are doing, and you get only questions from that situation. Choose riichi, call and kan decisions as well as discards.
- All Last in 3rd, opponent in riichi: push or fold?
- Early East round as dealer: go fast or build a bigger hand?
- Mid-game with an opponent's open melds: push, or play it safe?

Stuck on a move? Ask the AI right there.
When you can't decide what to discard, just ask Aria. Compare up to 3 of a strong mahjong AI's top candidates and read, in plain words, why that tile is the one.
- See up to the AI's top 3 recommendations
- Compare shanten and tile acceptance for each candidate
- Explains which tile it beats, and why
- Two explanation levels: Normal and Hard
Aria never stops at "because the AI said so." Every explanation rests only on facts you can check on the board, leaving you something to go on the next time a similar shape comes up.
Put what you learn to the test at the table, right away.
Play against AI anytime, even just a single game. Read the tiles, think, and discard on a table that fills your landscape screen. The thrill of winning a hand is part of the reward, too.
- 4-player and 3-player
- East-only, half game, or a single hand (East 1)
- Pick up where you left off
- 8 table colors to choose from
- Win effects that scale with your hand
The AI grades the way you play.
After a game, the AI reviews and scores every discard (analysis uses coins). Offense and defense, speed and hand value reveal your play style and the habits worth fixing.

Analyze games from other apps, too.
Just paste the game log URL from an online mahjong service, and the AI reviews every hand.
From tile basics to push-or-fold in real games.
Lessons follow Q-chan and Aria's conversation while you move tiles on the table. Then exercises and practice quizzes turn what you learned into your own judgment.

From the maker
Thành thật mà nói, với tôi việc học cũng phiền phức.
Mahjong is often dismissed as a game of luck. But over time, the difference lies in how you use the chances you get.
Mahjong is a skill you can build. You can improve. But even knowing that, opening a textbook can still feel like a chore.
We created Mahjong Q'z as a place where people like me can learn without the pressure.
Đầu tiên bạn học cách chơi khó bị đánh bại.
Tiếp theo bạn học cách thắng lớn.
Hãy nắm rõ khi nào nên phòng thủ, khi nào nên tấn công, rồi đánh giá lại theo bài trên tay, tình hình bàn chơi và điểm số. Sự tiến bộ đến từ việc lặp lại quá trình đó.
