Scores made by a player participating in a game can be tracked by using a sensor device coupled to the player to detect when the player attempts to make a score with a ball or other projectile. When a score is made, such as when something enters a goal, it is determined whether the projectile from the player is what made the score so that the score can be properly attributed to the player or another player. Attribution can be based on whether the score occurred within an appropriate time window, which could be computed from data from the sensor device. Attribution can also be based on the use of machine readable identifiers on the projectile, player, and/or goal.
