Round 1
49 contestants took part in this round, but only six would move on to round two. The host reads a question that can be answered by a number from 1 to 49. Anyone who thinks that their own number is the answer buzzes in. If the owner of that number buzzed, he or she moves on to round two. Anyone who buzzed but was wrong is eliminated. If the owner didn't buzz, but should have, he or she is out. This process repeats until 6 people qualify for the second round.
The last digit from each of the winner's numbers are shown at the end of the show. If all 6 numbers match the last 6 digits of your phone number in any order then you can call in to try to appear on the next show.
In series two onwards, this changed to the host asking the 49 contestants a question with a number for an answer. The contestants use keypads to enter their answers, and whoever is correct in the fastest time moves on to the second round. Contestants do not have to play a question and wrong answers eliminates all those who give them. This continues until six have qualified for the next round. All of the remaining 43 contestants are eliminated.
