The Mystery Event at Norwich Summer 2022 speedcubing competition

Norwich Summer 2022 will take place on 30-31st July in Norwich and I will have a stall selling my cubes there, I will also be running a mystery event on Sunday lunchtime. The puzzle for the mystery event is known only to me. It will consist of a race of 4 groups of 12 people, one group at a time with the other groups kept away while it takes place. It will consist of a puzzle being underneath a cube cover which must be solved with no inspection. View information about Norwich Summer 2022 here
