ID61-Joker Exchange Resulting in a Self-Picked Win
Question: If I do a Joker exchange and it results in my Mah Jongg, is it considered self-picked?
Answer: If a player does a Joker exchange which gives them Mah Jongg, it is considered self-picked. If playing for money or points, the payout would be double the value of the hand.
