Format of competitions was constantly changing. The very first edition of the competition in 1936 was a
single-elimination tournament (more precisely sudden-death tournament) throughout all rounds. It was played during the season's summer intermission of the 1936 split season. The tournament consisted of seven rounds starting with the Round of 128. The first changes took place in the
1938 Soviet Cup when there was introduced a preliminary (qualification) stage as the number of participants grew. The competition still was a
single-elimination tournament with only more added rounds (up to 9). The Soviet Cup also featured the
1938 Cup of the Ukrainian SSR. All teams of masters (All-Union league teams) started from the final stage. The competition rounds were in-mixed within the league's playing calendar for the first time. The final stage contained 6 rounds. In 1939 the competition was expanded as number of participants grew over 6 times. Starting from 1939 the preliminary stage was expanded and included republican football cup for each union republic, winners of which would qualify for the Soviet Cup finals. In 1940 the competition was split. The league teams (Groups A and B) were scheduled to play for the All-Union Sports Committee Cup, while non-league teams (republican level) were competing in a separate bracket, winner of which would play the All-Union Sports Committee Cup holder. However, due to scheduling issues the All-Union Sports Committee Cup was postponed and never took place. Involvement of the republican cup winners was suspended after the
World War II and reintroduced in 1949. Those winners continued to qualify for the Soviet Cup until 1955 and starting from 1957 they were rerouted to the
Soviet Amateur Cup. There is a legend that during that period the competition was nicknamed as the "Cup of Millions". Until 1984 the Soviet Cup corresponded to the calendar of the whole Soviet football "spring"-"fall", however after that it changed to "fall"-"spring" calendar which synchronized it with the most of Europe. In 1959-1960 the competition was conducted for two years. From 1965 to 1968 seasons were overlapping each other. Until 1957, in the tournament participated "teams of physical culture" All tournaments final were played in a single game in Moscow, but until introduction of penalty kicks in early 1970s as a tiebreaker some finals that ended in tie were replayed. Introduction of the
penalty shoot-out was adopted for tiebreaker took place in 1972 after such procedure was adopted by
FIFA in 1970. Until 1955 the tournament finals were played at
Central Stadium "Dynamo", after being transferred to Central Stadium of Lenin (today
Luzhniki Stadium). ==Trophy==
