To organize an indoor soccer tournament, rent an indoor facility, invite the teams you want to compete and ensure there are enough soccer balls, cones, markers, flags and nets to spare. Once you have a confirmed number of teams, create a format for the tournament and schedule bookkeepers and referees.
Work out the stages of the tournaments by establishing a first knockout stage. This is determined by either a draw or any standings the teams have already established in a regular season. If there are an odd number of teams, give one team a bye in the first round or establish a group stage of games to determine who plays in the tournament. Create a visible bracket with poster board or purchase a dry erase bracket from a sporting goods store and post it at the entrance of the facility. The winners of each bracket play each other until there are only two teams left in a final game.
Purchase trophies to distribute to the top three or four teams after the final in a presentation ceremony. Medals or small trophies are appropriate for any other awards, such as high scorer, most valuable player or all-around sportsman. Clean up the facility and collect all equipment once everyone leaves.
