<P> The values on the board range from $1 to $25,000, and are arranged as follows: </P> <Table> <Tr> <Td> $1 </Td> <Td> $5,000 </Td> <Td> $100 </Td> <Td> $20,000 </Td> <Td> $10 </Td> <Td> $10,000 </Td> <Td> $1 </Td> <Td> $25,000 </Td> <Td> $1 </Td> <Td> $10,000 </Td> <Td> $10 </Td> <Td> $20,000 </Td> <Td> $100 </Td> <Td> $5,000 </Td> <Td> $1 </Td> </Tr> </Table> <Tr> <Td> $1 </Td> <Td> $5,000 </Td> <Td> $100 </Td> <Td> $20,000 </Td> <Td> $10 </Td> <Td> $10,000 </Td> <Td> $1 </Td> <Td> $25,000 </Td> <Td> $1 </Td> <Td> $10,000 </Td> <Td> $10 </Td> <Td> $20,000 </Td> <Td> $100 </Td> <Td> $5,000 </Td> <Td> $1 </Td> </Tr> <P> At the start of the second round, the contestants are separated from each other for the remainder of the game . One enters an isolation chamber behind The Wall, while the other remains onstage . Two green balls are played simultaneously, dropped from zones chosen by the onstage player . 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 zone to use, based on how confident he / she is that the isolated player can answer correctly . The question and answers are then presented to the isolated player; after he / she responds, the ball is dropped from the chosen zone . A correct answer turns the ball green and adds the value of the slot it lands in to the team bank, while a miss turns the ball red and deducts the value . The isolated player is not told which of his / her answers are correct or given any information on the team bank . </P>

Where does the money from the wall come from
