The goal of the competition is to beat your opponent by keeping a biscuit dunked in a hot drink for as long as possible.
Every one second you hold your biscuit dunked is another one point.
However, the biscuit must stay intact upon removing it, otherwise you get zero points for that round.
The points will accumulate over three rounds, and the player with the highest points wins.
Contestants (Dunkers) go head-to-head across three rounds of biscuit dunking.
Each round is called a ‘dunk off’.
Dunkers must select a hot drink of their choice for dunking.
The drink must remain the same across each of the three rounds.
Drinks should be maintained at a temperature of 60-65˚C.
Dunkers must select their favourite McVitie’s biscuits to dunk.
