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

Rules and gameplayEdit

Two contestants attempt to predict the results of polls in a best-of-five elimination round. A question is read and the two contestants are given ten seconds to lock in their guess using a dial to select a percentage. If a contestant has not locked in their guess after ten seconds, the computer locks in the percentage the on which the contestant had currently rested. The player who comes closest to the actual percentage earns a point. The first player to earn three points advances 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 is given similar questions, and places a range on a scale from 0% to 100% that they believe includes the correct answer. The size of the range decreases as cash awards increase:

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 is revealed once the contestant locks in an answer by pulling down a handle or lever. For the $100,000 question, the correct answer is only revealed if the actual percentage is outside of the contestant's range. If the contestant correctly answers 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 is not within range, the game is over. If the contestant missed either the $100 or $1,000 question, the contestant leaves empty-handed. From the $10,000 question onward, missing a question decreases the contestant's winnings by the power of 10, meaning that he/she leaves with 10% of the money accumulated to that point.

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

The host is not made aware of the answers prior to the reveal and sometimes helps contestants think through questions and offered their own opinions, unlike most game shows.
