This is a small expansion for the base-game Shanghaien. It is based in an extra "dirty tricks" card called "Send to the sharks / Exchange".

Every player gets one at the beginning of the game. He can use it one time during the game like every other "dirty tricks" card.

Using it he can choose between two actions:

- “Send to the sharks”: The player flips the card of the tavern onto which he has added a die in the same
turn onto its back side. When the cards are distributed, cards of the tavern which are flipped over are
removed from the game regardless of dice added onto them. Nevertheless dice added to a flipped card still
count as tie-breakers for adjacent cards which are not turned over. The “dirty tricks”-card is removed from
the game after usage.

- “Exchange”: The player takes one of his own dice he has added to a card of the tavern in a previous turn
back to his supply. Then he adds both dice he has rolled in that turn onto the corresponding cards of
the tavern. This action can only be performed if the player has added at least one die to the tavern in a
previous turn. The “dirty tricks”-card is removed from the game after usage.
