At the beginning of a round, after one player is dead, if you have 3 cards of a month in your 7 Hand cards, you show those 3 cards by Waving them to the other 2 players in the first turn. In case you become the winner, your points will be doubled.
* Note 1: If you fail to Wave them within the first turn, you cannot double your points as the winner. (Better not show them if you miss the first turn)
* Note 2: If you forget to double your points as the winner, the other players and the dead player are not required to remind you. So don't forget, or you'll be cheated half of your winnings!
