The tournament would be disputed in a double round-robin format, with the team with the most points winning the title. The team with the fewest points would dispute a playoff against the champions of the second level.[2] [1]
The regulation also stipulated that the runners-up of the championship would also receive a trophy. Since São Cristóvão and Botafogo tied in points for that position, they had to dispute a playoff.[1]
The last-placed team, Mangueira, would dispute a playoff against Americano, champions of the Second Level. Mangueira won the playoff.[1]
