All 20 skateboarders did two 45-second runs, and then five single tricks rounds. Only the top 4 scores from the seven rounds for each skateboarder counted toward the final score. The top 8 skateboarders from the Semi-Final qualified for the finals, where the scores were reset and follow the same two 45 second round and five single trick round format.
