Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.

About Mahjong Book: Learn Riichi
Mahjong Book brings learning, scoring and playing Japanese riichi mahjong together.
LEARN THE TILES
Explore tile types, winning shapes, waits, yaku, dora, fu and scoring through tile-based lessons and quizzes. Spaced repetition helps you review. Look up a yaku or unfamiliar term in the built-in references.
EXPLORE TILE EFFICIENCY
Chapter VII covers shanten, ukeire, visible tiles and lookahead. The on-device lab compares every discard in a closed 14-tile hand over your next two draws. Generate exercises or enter your own tiles. It compares a stated structural target, not real-game win rates, value or defense.
ENJOY THE MUSIC
Listen to all 19 bundled tracks in the Music Library, with seeking, repeat and shuffle. No streaming connection is needed.
PUT IT INTO PLAY
Play 4-player or 3-player mahjong on a 3D table against beginner, intermediate or advanced AI. Tap a tile to select it, then tap it again to discard. Practise what you learn, one decision at a time.
UNDERSTAND THE SCORE
In Scoring Training, winning hands from AI matches become fu and scoring questions. See the explanation whether your answer is right or wrong. The hand payment, honba bonuses and riichi deposits are shown separately, so you can follow how the final total is formed.
PLAY WITH FRIENDS OR THE WORLD
Join a worldwide table or create a private room with a 4-digit code. Worldwide tables fill empty seats with AI two minutes after recruitment starts. Chat is limited to preset phrases shared within the same room; there is no free-text chat. Online play requires an internet connection.
SWITCH THE APP TO ENGLISH
The in-app language button lets you switch between English and Japanese at any time. Lessons and AI matches work offline.
One-time purchase. No ads, no in-app purchases and no gambling.
