Tengan: Riichi Mahjong Coach

Tengan is real Japanese riichi mahjong that reveals the whole wall after every hand, so you can replay "that one discard" on the real wall and get stronger. --- Look back with what-ifs --- - After each hand, the whole wall is revealed, including the tiles you would have drawn - Pick one of your discards to see your hand and who was in tenpai, and on what wait, at that moment - Pick another tile from that hand to replay the real wall as if you had cut it: would you have dealt in (to whom, for how much), reached tenpai, or won? - Or play on from that spot yourself on the same wall. The others cut the same tiles they really did - When you missed a win, the result screen shows it in one line: "keeping that tile would have won 8000" - Luck and decisions: compare your starting hand and draws with expectations, and each discard with the most efficient choice --- See yourself improve --- - Climb the ranks in CPU games, from 10 kyu up to 10 dan - Stats: average placement, win rate, deal-in rate and your play style - Which tile?: a daily problem and problems from spots where you hesitated, each with an efficiency breakdown --- CPU games --- - East-only or East-South games, three CPU strengths. Strong CPUs push and fold - Rules such as open tanyao, red fives and rounding up to mangan - Yaku, fu and points are all calculated automatically with a full breakdown - Hints for shanten and waits help first-time players - Play in portrait or landscape --- Play with friends too --- - Gather with one room code. No sign-up needed - Empty seats are filled by CPU players, so two or three people can start - The server deals and judges; other players' hands and the wall are never sent to your device - The app checks that the revealed wall is the same one the hand started with. In friend rooms every device contributes randomness to the wall, so not even the operator can arrange it --- About Tengan Plus (subscription) --- Tengan Plus is an optional auto-renewing subscription (in-app purchase, monthly or yearly plan). - No ads - Every table style - Unlimited problem book - Unlimited what-ifs - Stats analysis (strengths, areas to improve, recent placements) Table styles are cosmetic only and never affect strength or the tiles you get. --- Other in-app purchases --- - Remove Ads (one-time purchase): removes ads only, forever. - What-If Tickets (5 or 30 opens): one what-if per round is free; tickets open more.
