These new rules contain a couple of new cards and mechanics which are not implemented on BGA (rulebook 2.1):
* Gift card
* Protection card
I have not checked every detail, but have also detected a change in the current cards: When swapping cards, the game continues with the player with whom the cards have been swapped.
Apart from that they have added the rule that the game has to start with a normal card (this question arose while developping the game for BGA).
