The first stage of Amplify III is the group stage. In this stage, teams compete in round-robin fashion against each other team in their group. Each team's goal is to place as high in their group as possible, with wins being worth 2 points in the group standings, draws 1 point, and losses 0 points. After playing each team in their group once, teams are seeded into brackets based on their group stage positions: the top 2 teams in each group proceed to the Premier bracket, while the bottom 2 move on to the Amateur bracket. The top 4 ranked teams in each bracket will receive a bye (free pass) for the first round of the elimination stage.
