The Wall is 4 stories high and “can change lives”. The game is played by two people together. The first portion of the game is Freefall. Contestants must answer questions before balls complete their free fall down the Wall – correct responses earn prize money (green ball), incorrect answers result in prize money being removed (red ball). This portion of the game results in a total dollar amount, that amount must be positive in order to move forward. The second portion of the game involves one of the two contestants going into isolation. Round two starts with two green balls, and two red balls. The player in isolation answers questions “under stressful situations” to determine the color assigned to the remaining balls. Up to six balls can be earned by answering 3 questions. The dollar amount earned in round one is added to whatever is earned in round 2. Players cannot leave this round with less than $0 even if the red balls result in amounts larger than the green balls plus the earnings from round one. The third portion of the game leaves the same contestant in isolation Four green and four red balls are given to start the third round. The player in isolation answers three more questions that can earn up to six balls (again earning green balls for correct answers, red balls for incorrect). The player in isolation then chooses whether to leave the game with the the guaranteed earnings from round 1 plus $20 thousand for each correct answer (not knowing how many questions were correct), or the result of round 2 and round 3.
