Practice
Then practice until it's second nature
Once the lessons click, focused drills keep them sharp. Each runs on a real rules engine — not flashcards — computing how far a rack is from any hand, which hands are still possible, and why one line beats another.
Card reading
See a hand's notation, name the tiles it needs — or go the other way, from tiles to the right section. Build notation fluency.
Hand selection
Deal 13 tiles, pick which hand to chase. The engine scores your choice on distance, joker flexibility, and tile availability — and explains the better line.
Tiles-away estimation
Guess how far your rack is from a target hand. The engine reveals the true number — the coach that competitors hand you passively is a drill here.
Charleston trainer
Given a starting hand and a pass direction, practice which three to pass — with feedback on whether the pass improved your position across viable hands.
Defense reading
Study exposures, name the hands they're consistent with, and answer the question that wins games: is this discard safe?
Jokers & dead hands
Know when to use, hold, or exchange a joker — and recognize the moment a hand can no longer be made from what's on the table.
Mastery & spaced repetition
Practice what you're actually weak at
Mahjee scores your mastery per section and per hand, then a spaced-repetition scheduler resurfaces the ones slipping away — so your practice time lands where it moves the needle, not where you're already sharp.
- Every drill outcome updates a per-hand mastery score.
- Weak sections come back on schedule, before you forget them.
- Load a new year's card and section-level intuition carries over.
Engine-first
Built to load any year's card
The value lives in the engine, not any single card. Under the hood, every hand is machine-readable structure the trainer can match your tiles against — which is what makes real coaching possible.
Cards are data, not code
A new year ships as a validated data pack — no app-store release to add a card, and transcription errors get hotfixed without one either.
One engine, every card
The trainer never hard-codes a hand. It operates over whatever card is loaded, so the same drills work on next year's card the day it drops.
Offline-first
Drills and solo play work with no connection. Your card ships in the app; progress syncs quietly in the background when you're online.
