Its original name Oh Hell! evidently offended some people and has been bowdlerised in many books to Oh Pshaw! or Oh Well!, while others have preferred more robust alternatives such as Oh Shit! Some call it Blob or Blackout, perhaps because of the practice of recording a player's bid on the scoresheet and then obliterating it with a black blob if the player failed to take the predicted number of tricks.  Traditionally the size of the players' hands increases or decreases by one in each deal, and this has given rise to the names Elevator (l'Ascenseur in France), Up and Down the River (in Australia and New Zealand) and 10 op en neer in the Netherlands.  In Britain it is often known as Contract Whist or as Nomination Whist, Other names include Bust (in Australia and New Zealand), Boerenbridge (in the Netherlands) and German Bridge (in Hong Kong).  In India the game is called (in Gujurati) Kachuful, which is a mnemonic for the order of cycling through the trump suits: Kari (spades), Chukat (diamonds), Falli (clubs), Lal (hearts).

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 In the simplest version, a player who wins the exact number of tricks bid scores 10 plus the number of tricks bid (10 points for zero tricks, 11 for 1 trick, 12 for two tricks, etc.) Players who take more or fewer tricks than they bid score nothing.  This method has the advantage that the scorekeeper, having written down the bids at the start of the play, can simply write a figure "1" in front of those that were successful and delete those that are not.  The game with this scoring method is often known as Blackout or Blob, because the scorer obliterates or blacks out unsuccessful bids, so that they become black blobs on the score sheet. *** KACHUFUL CARD GAME FEATURES *** BONUS COINS: -Get 50,000 coins as a Welcome Bonus to the kachuful card game, and get even more coins by collecting your “Daily Bonus” every day!
