Powerof10 733x150
Nine Network: 31 March 2008 – 7 April 2008

Power of 10 was based on a U.S. format of the same name. It featured contestants trying to guess the correct percentage range of answer to polls which have been taken from surveys, for a chance to win $1,000,000.


Two contestants competed to predict the results of polls in a best-of-five elimination round. A question was read and the two contestants were given ten seconds to lock in their guess using a dial to select a percentage. If a contestant had not locked in their guess after ten seconds, the computer would lock in the percentage the on which the contestant had currently rested. The player who was closest to the actual percentage earned a point, and the first player to earn three points advanced to the money round to play for the top prize.

For any question except the million dollar question, if a contestant guessed the actual percentage, they won an instant $1,000.

In the money round, the contestant was given similar questions, and placed a range on a scale from 0% to 100% that they believed included the correct answer. The size of the range decreased as cash awards increased:

Question # Question Value Percentage Range/Margin of Error
1 $100 40%
2 $1,000 30%
3 $10,000 20%
4 $100,000 10%
5 $1,000,000 Exact/Dead on (see below)

For the first three questions, the correct answer to the question was revealed once the contestant locked in an answer by pulling down a lever. For the $100,000 question, the correct answer was only revealed if the actual percentage was outside of the contestant's range. If the contestant correctly answered the $100,000 question, they are then given the chance to win $1,000,000 by picking the exact percentage (rounded to the nearest 1%) out of that 10% range.

If the contestant's guess was not within range, the game is over. If the contestant missed either the $100 or $1,000 question, the contestant would leave empty-handed. From the $10,000 question onward, missing a question decreased the contestant's winnings "by the power of 10", meaning that he/she would leave with 10% of the money accumulated to that point.

For each question, audience members would make exact-percentage guesses in order to show the contestant a full sample of the results for help in answering. Contestants could also ask an in-studio relative or friend their opinion before locking in, and contestants could adjust their choice if necessary to elicit reactions from the audience or their friend/relative. Contestants could stop the game and take the money that they currently had until locking in an answer.

The host was not made aware of the answers prior to the reveal and sometimes would help contestants think through questions and offer their own opinions, unlike most game shows.
