Oh Hell!

Oh Hell! is a trick taking standard deck playing card game. The object is for each player to bid the number of tricks he thinks he can take from each hand, then to take exactly that many no more and no fewer. Points are awarded only for making the bid exactly, and are deducted for missing the bid, either over or under.The hook is that at least one player will fail on each hand, because the total number of tricks bid by the players may not equal the number of tricks available on that hand.Also known as Oh Pshaw and Blackout. - BoardGameGeek
