The game consists of five rounds; before each of the first four, a different question is used to split the contestants into two teams, or "tribes," based on their responses.
The host asks a series of questions on the buzzer to the lower-scoring tribe; a correct answer allows a member to advance, while a miss eliminates them.
If the round ends in a tie, each tribe nominates one member for a one-question tiebreaker, played under the elimination rules above.
A correct answer forces the opponent to start, while a miss requires the responding contestant to do so instead.
The clocks were set to 60 seconds, and the winner received £1,000 worth of vouchers for their choice of two different merchandise types (e.g. gardening equipment or books).
Correctly sorting out all four names awarded a jackpot, which began at £1,000 after it was won and increased by that amount every day it went unclaimed.
