For the sixth and final qualifying spot there was a three-way tie at 13½ points. Leonid Stein (USSR), Pal Benko (USA), and Svetozar Gligorić (Yugoslavia) played a double round-robin playoff tournament which was dominated by Stein and Benko. Although Stein won, a rule adopted in 1959 allowed no more than three players from a single Federation to qualify from the Interzonal. Stein could play in the Candidates only if one of the other qualifiers from the USSR (Geller, Petrosian, or Korchnoi) was unable to participate. With Stein excluded, Benko took the final place in the Candidates Tournament.
