In this event (Rubik's Cube: Blindfolded), competitors firstly memorise all the pieces without applying moves.
The competitors can turn the puzzle after they put a blindfold.
The scramble was generated by a computer, and it was the same for all the competitors.
The rank of this event is determined by the time, including both memorization and execution.
Mr. Tomoyori starts the solve at 22:00. The awesome moment can be seen at 25:00.

(from 22:00)
In addition to the competitor's blindfold, a judge inserts a board between the puzzle and the competitor, in order to prevent the competitor from cheating.
(from 25:00)
The successful solve by a 80-year-old person is a world record at this moment (May, 2013).
(from 25:30)
The timer with display does not work if the time exceeds 10 min. Therefore another timer (stopwatch) was used for recording his time.
His official record is 26 minutes 29 seconds (according to the WCA regulation).
He is also famous for a previous world record holder for remembering pi.
