MahjongQ
Read full descriptionHide full description
Learn Japanese (riichi) mahjong from zero. MahjongQ takes you from "what is a tile?" to building winning hands, in Japanese or English. LEARN: 12 short lessons Tiles → the winning shape → how a game flows → tenpai and waits → yaku → ron, tsumo and furiten → calls (pon, chi, kan) → dora and scoring → defense → common rules and placement points → thinking at the table. Each chapter ends with a quick check and takes 3–8 minutes. QUIZ: 6 types • Tile names • Spot the meld (run or triplet) • What's the wait? • Name the yaku • What to discard? (graded by useful tiles, with an explanation) • Score it (han and fu → points) SOLO: tile-efficiency practice A single-player exercise: draw one tile and discard one, for up to 18 turns, and try to reach tenpai or complete a hand. With hints on, each turn shows which discard keeps the most useful tiles, and why. Complete a hand by tsumo and you see its yaku, han and score. No opponents and no exchange of points. REFERENCE: memorize the combinations • Yaku catalog: 28 yaku with example hands and a memorize mode • Tile catalog, score table, glossary OTHER • Switch between English, Japanese and Traditional Chinese any time • No account, no ads, no network. Progress stays on your device • No betting features, no purchases, no real money of any kind • Free

Verdict
The clearest difference is ads: MahjongQ at none against 慣用句 !'s shown. MahjongQ also leads on update cadence (every 4 days vs every 3 months). 慣用句 !'s advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price and in-app purchases there is nothing between them.
