Attempt 2 - 6 2/3 minutes

Attempt 3 - 13 1/2 minutes

Attempt 2 - 10 minutes

Attempt 3 - 20 minutes

1. A recorded tape is played that has a clear voice reading out decimal digits in English (1,5,4,8 etc) at a rate of 2 seconds per digit.
2. Attempt 1 - 100 digits are spoken
3. Attempt 2 - 200 digits are spoken
4. Attempt 3 - 400 digits are spoken.
5. No writing is allowed during the playing of the tape.
6. When a contestant has reached their limit that they can memorise, they must stay in their seats, be quiet and sit still for the remainder of the tape.
7. If for some reason the attempt has to be abandoned due to an external distraction, the attempt will be repeated with a new tape.

1. Contestants must write their recalled numbers in consecutive order from the start of the spoken sequence.
2. Contestants may use blank paper, the answer sheets provided (an example is provided with these rules at Annex B), or their own (as long as it has been cleared by the adjudicator before recall commences).

1. One point is awarded for every correct consecutive digit that the contestant writes down from the first digit of the spoken sequence.
2. As soon as the contestant makes their first mistake, that is where the marking stops.
3. For example if a contestant recalls 127 digits but makes a mistake at the 43^rd digit then the score will be 42. If a contestant recalled 400 digits but made a mistake on the first digit the score would be 0.
4. The winner of the event is the contestant with the highest score.
