When you draw a Mysterious Place Card, you must immediately place it face up in front of you and draw another card. Mysterious Place Cards may not be kept in your hand. If a player is given a Mysterious Place card during the initial deal at the start of the game, or picks one from the Draw Pile during play, then the card is saved and the player draws another card. This is very similar to how players save Kaballa Dolla and Zodiac cards. Many new cards will refer to these saved Mysterious Place cards during play.
After the initial deal, and once game play begins, any player who draws a Mysterious Place card will take control of the Yellow Ball (with the Red Stripe). The Yellow Ball will always be placed on top of the last Mysterious Place card that was drawn. The player who has control of the Yellow Ball may control the destiny of any card played by any opponent that has a Yellow Ball in the picture. The opponent must play the card first, then the player may redirect it to any other player, bunny or the Discard Pile. Control of the Yellow Ball will always reside with the player who drew the last Mysterious Place card.
At the end of the game (before the Winning Zodiac is revealed), the small deck of Mysterious Place Cards, hidden away at the start of the game, is inspected. The player holding the Mysterious Place card that matches the picture on the small Mysterious Place Card at the bottom of the deck is allowed to steal all saved Zodiac cards of any one type (Air, Earth, Fire, Water) from any opponents.
It is possible that at the end of the game no player is holding the matching Mysterious Place card. If this is the case, then the game simply continues by revealing the Winning Zodiac using the small deck of Zodiac Cards.
