It is necessary to win in seven games inside "the Cube" in the show. Every participant has nine lives. If participant doesn't pass a trial, he loses one life. After passing a trial a player can take the money he has won and finish the game. But if during one of the tasks a player looses all lives, he will finish the game without winning anything. If participant reaches the last, seven's game, then he is offered to take once again one of the six games he has already passed but in more complicated version. If participant passes the seven's game, he becomes the winner and gets the main prize.
