Read the situation, decide the ruling, then check yourself against the card. Every answer reveals the exact 2026 NMJL card wording pulled from this site's primary rule authority — so you are not memorizing someone's paraphrase, you are reading the source. Free, no account, and your score stays on this device.
These drills use only general, public-domain rule principles from the 2026 NMJL card — dead hand, jokers, Charleston, claiming, exposure, erroneous Mah Jongg, and misnamed tile. They do not reproduce any year's specific card hands or winning-line values.
2026 Rule Mastery is a verification drill. Each question is keyed to a rule in the site's primary 2026 authority (built from the official card the editor scanned), and the card's own wording is shown after you answer.
The point is not trivia. It is to train the calls that decide real games — when a joker can stand in, whether a dead hand still pays, what a wrong Mah Jongg call actually costs, and who takes a contested discard.
