Blind Mouse Bluff

From BoardGameGeek:

Blindly seek out cheese with only your untapped senses. Are the other players bluffing? Are you? Be careful, though. If you reveal a blind mouse, others will get the reward. Reveal three and the game is over. Players will each create a pile of face down cards in front of them that may be cheese or it may be a mouse. Once everyone has placed at least one card in their stack, they can continue to place card or start the bidding. Use your best skills at reading the other players while keeping your own Poker Face to determine where the best cheese may be placed – but be careful not to reveal a mouse. -Description from Designer
