Showdown is the bidding game where bluffing is perfectly OK, as long as you don't get caught! Bid how many of a given number appear on the cards held by all players together. For instance, "Four 5s". Next player must make a higher bid or Challenge yours. Once bidding ends, the cards are shown. Stars count as the number bid. If the Bid was too high, the Bidder loses a card. Otherwise, the challenger loses. Try to guess other player's hands by their bids, but remember, bluffing can be quite effective (unless you get challenged!)
