How the drill works
Each round shows a table state and asks you to choose the safest (or most dangerous) discard. You get instant feedback tied to the same principles as our Defensive play lesson. No account, no backend — just reps.
Practice, not the rulebook
These are teaching scenarios built around real American-mahjong principles (eight jokers, no furiten, a discarded joker is dead). The actual call always comes down to the live table and the current NMJL card — read the table, don't trust table talk.
