When a card is played, the other players must follow suit (play a card of the same suit) if possible. A card is beaten by a higher card of the same suit or any trump card. The rules of play are those of standard trick-taking games. The winner of the game is the player with the most points after a fixed number of rounds. The aim of the game is to score points by winning tricks (each trick scores one point) and by correctly predicting how many tricks you will win each round (this scores 10 points per round). The premium version is a completely ad free game. Also knows as Contract Whist, Oh Well!, German Bridge, Blackout or Up and Down the River. Oh Hell! is the world's most popular trick-taking card game in which the object is to take exactly the number of tricks bid.
