Bluffun

Shuffle the deck and deal each player five cards. There is one draft phase followed by the play phase. Draft Phase Players select one card from their hand to set aside, then pass the remaining cards clockwise. When all five cards have been selected the play phase begins. Play Phase Draw a card, then discard down to five cards. Cards are always discarded to a face down pile. OR Declare a three of a kind by calling out the number and placing three cards face down. If no other player contests, discard played cards and score points according to the number declared. If another player calls, you must reveal the played cards. If you were caught bluffing lose points equal to the highest played card. If your opponent incorrectly called, they lose points equal to half that card value rounded up then score points as usual. When the last card has been drawn the round ends (3-4 players, shuffle and play an additional round). The player with the most points is the winner. Tied players share the victory. —description from the designer
