Common questions
Which is easier to learn for a complete beginner?+
Hong Kong. Fewer patterns, no fu calculation, simpler payout math. Riichi adds layers (fu, dora, riichi, ippatsu) that take time but reward learning.
Why do anime characters play Riichi?+
Riichi is the standard Japanese variant, so anime set in Japan defaults to it. The dramatic riichi declaration with sticks is visually distinctive and makes for good storytelling.
Is one more 'authentic' than the other?+
No — both descend from older Chinese mahjong, both have ~100 years of independent evolution. They're cousins, not parent-child.
