Gameplay
The Wall is a four-story tall (40 ft) pegboard, similar to a pachinko game or bean machine; it also is similar to the board used for the Plinko pricing game on The Price Is Right . The bottom of the board is divided into 15 slots marked with various dollar amounts, alternating between low and high values. The eight low values range from $1 to $100 and remain constant throughout the game, while the seven high values are $5,000 or more and increase from round to round. Balls can be put into play from seven numbered "drop zones" on the top edge of the board, directly above the seven centermost money slots.
A team of two contestants plays each game, attempting to bank as much money as possible by answering questions correctly and landing balls in high-value slots. [9] [10] Green balls add the values in which they land to the team's bank, while red balls deduct theirs. Throughout the game, the bank has a floor of $0.
Round 1: Free Fall
In Free Fall, the team is asked a series of five questions, each with two answer choices. As each question is asked, three balls are simultaneously released, one apiece from drop zones 1, 4, and 7. The team must select one answer and lock it in before any ball crosses the threshold of a money slot. Once the balls have landed, they turn green for a correct answer, or red for a miss or failure to lock in a choice in time.
If the team's bank balance is zero at the end of this round, the game ends immediately and they leave without any winnings. Otherwise, their earnings become part of a guaranteed payout to be offered to them at the end of the game.
Starting with Season 4, the team may choose to double the total value of any one question by pressing a gold "Free Fall Plus" disk while the balls are falling.
The highest amount that a team can bank in this round is $375,000 in the first three seasons; this was later increased to $450,000 for the fourth season.
The values on the board range from $1 to $25,000, and are arranged as follows:
| $1 | $5,000 | $100 | $20,000 | $10 | $10,000 | $1 | $25,000 | $1 | $10,000 | $10 | $20,000 | $100 | $5,000 | $1 |
Round 2
At the start of the second round, the team chooses one member to enter an isolation chamber for the rest of the game, while the other remains onstage. A set number of green balls are played simultaneously at the beginning of the round. Three multiple-choice questions are then played, each with three answer choices. The onstage player is shown only the answers to each question and must decide which drop zone to use, based on how confident they are that the isolated player can answer correctly. The question and answers are then presented to the isolated player. After they respond, the ball turns green for a correct answer or red for a miss, and is then dropped from the chosen zone. The isolated player is not told which of their answers are correct or given any information on the team bank until they are brought out of isolation near the end of the game.
The onstage player is offered an opportunity to "Double Up" on the second question and "Triple Up" on the third. These options allow the onstage player to play two or three balls from the selected drop zone instead of one, respectively. After the third question, if the banked total is at least $1 more than the number of green balls played at the start of the round, an equal number of red balls are played simultaneously from the same zones; if not, the bank is automatically reset to $0.
In the first two seasons, two initial green balls were played from different zones chosen by the onstage player, and a team could bank up to $1,999,998. Beginning with the third season, seven initial green balls are played in a "SuperDrop," one from every zone, and a team could bank up to $3,249,993. The maximum slot value was reduced from $250,000 to $150,000 at the beginning of the fourth season, lowering the potential total for this round to $1,949,993.
Starting in the fifth season, the contestant is given an additional "Wall to Wall" option on the third question, allowing them to play seven balls as in the SuperDrop. [11] The maximum that can be banked in this round is thus increased to $2,549,993.
The values on the board range from $1 to $250,000 (later $150,000) and are arranged as follows:
| $1 | $5,000 | $100 | $10,000 | $10 | $25,000 | $1 | $50,000 | $1 | $100,000
$75,000 | $10 | $125,000
$100,000 | $100 | $250,000
$150,000 | $1 |
Round 3
Gameplay proceeds as in Round 2, but each of the three questions now has four answer choices. In addition, four green and four red balls are played at the start and end of the round respectively, and are dropped one at a time, rather than simultaneously. The "Double Up" and "Triple Up" options are available as before. The maximum amount that a team can bank in this round is $9,999,996.
The values on the board range from $1 to $1 million, and are arranged as follows:
| $1 | $50,000 | $100 | $100,000 | $10 | $200,000 | $1 | $300,000 | $1 | $400,000 | $10 | $500,000 | $100 | $1,000,000 | $1 |
Final Decision
After the third question in Round 3, the isolated player is sent a contract by the host and must decide to either sign it or tear it up. Signing the contract gives up the team bank in favor of a guaranteed payout, equal to the Free Fall winnings plus an additional $20,000 for every question answered correctly in Rounds 2 and 3. Tearing up the contract or returning it unsigned awards the team their final bank total. If the bank contains at least $5, the four red balls are played once the isolated player returns the contract, from the same zones and in the same order as the four green ones at the beginning of Round 3. If the bank contains $4 or less, it is set to zero and the red balls are skipped. The isolated player then returns to the stage to reveal their decision; only at this point do they learn the number of correct answers given, the payout total, and the team's final bank.
The maximum possible guaranteed payout in the first two seasons is $495,000, obtained by scoring $375,000 in Free Fall and answering all six questions correctly in Rounds 2 and 3. The maximum possible bank total in the first two seasons is $12,374,994, obtained by answering every question correctly, using every Double Up and Triple Up option, having every green ball drop into the highest-valued slot, and having the six mandatory red balls each drop into a $1 slot. In the third season, the maximum possible total is $13,624,989 due to the increased number of mandatory green and red balls in Round 2. For the fourth season, the maximum payout and bank totals are $570,000 and $12,399,989, respectively, achieved through use of the double-value option in Free Fall, and the reduced maximum slot value in Round 2. With the introduction of the "Wall to Wall" option in the fifth season, the maximum bank total is $12,999,989.
