In contrast to the normal game of whist, the trump colour is determined by a bidding process rather than being the last card on the stack.
The number of tricks usually starts at five or six if a player is alone and at seven or eight when he has a partner, these specifics are very much subject to change.
Some player groups may choose to play without small misery, picollissimo and picollo, as these "special modes" are otherwise chosen too often.
Some groups also play without the possibility of re-dealing when all players bid on different suits.
Note that if a game is 2vs2 each player will win or lose this number of points.
