But NHS Orkney's Director of Public Health, Dr Louise Wilson said: "We are very concerned about young people putting themselves into danger.
"Mixing high volumes of alcohol and consuming quickly can prove fatal, particularly in young people. We certainly don't want the Orkney community to experience a tragedy as a result of this 'game'."
