The format was the same as in 1964, with the best six gymnasts in the individual all-around advancing to the apparatus final, with the final apparatus score made up of 50% of the all-around total and a final optional program. The 1966 World Champion was Soviet Sergey Diomidov, but he placed only 23rd in the all-around qualifying and did not make the final. The gold went to Japan’s Akinori Nakayama, who also won gold on the horizontal bar and rings in Mexico City, winning three apparatus golds. Silver and bronze went to Soviet gymnasts, Mikhail Voronin and Viktor Klimenko, respectively. Voronin had also been silver medalist on parallel bars at the 1966 Worlds.
