A total of eight men's teams qualified to compete at the games. At least four out of the six Commonwealth regions were considered to be represented in each tournament, if possible.[3] For the home nations, each country may compete, however the ranking of Great Britain was given to the home nation with the most players on the team. The teams were officially confirmed on July 28, 2017.[4]
The tournament was held under an unusual, seeded-group format.
The host nation, along with the top three teams in the FIBA Rankings played in higher group, group A. The other four teams played in the lower group, group B.
The top two teams in group A after the preliminary round advanced to the semifinals, while third and fourth place entered the quarterfinals where they played the top two teams in group B from the preliminary round. The bottom two teams in group B were eliminated.[5] The winners of the quarterfinals proceeded to meet the semifinalists in a straight knockout format.
