A first hand to try, and proposed rules to share
Finish the shape. Find the Tai. is a short guided browser exercise: finish a pair, identify the Red Dragon Tai, then compare a complete hand that cannot Hu. It uses fixed practice rules and needs no installation.
The First Hu teaching kit adds a learner worksheet, a separate facilitator answer key and a QR link back to the exercise. Its suggested 15-minute activity uses the same two fixed examples. Hosts can print them separately or download two A4 PDFs. The lesson now offers an optional teaching handoff, two prompts, a copyable invitation and a same-phone reset for the next learner.
Table invitations now let guests read proposed settings and try a question before saving a separate copy. Arriving and answering leave their active table alone. The sender can preview the name included in the link.
The guide now offers clear starting paths and a local font. Bao explanations require an actual completed claim; the later-self-draw example uses a fourth same-suit set, because the third Dragon set ends the hand automatically here. Added-Kong and Chow-route explanations were also corrected. See the correction record. These are web changes; they do not claim a new Android binary or universal agreement on house rules.
