Frequently asked
Is Mao really unteachable?+
The convention is that RULES ARE NEVER EXPLICITLY TAUGHT — newcomers must observe + deduce. In practice, groups vary from strict 'never explain' to friendly hints. Core mechanic (shedding, playing on suit/rank) is straightforward; the FUN is in slowly discovering 5-15 quirky penalty rules the dealer has stacked.
