Disclosed are method and system for automatic identification of at least one player. The system and method are associated with a processing unit, and at least one projectile having a wireless interface and at least one sensor. The sensor collects sensor data at a first moment of time before release of the projectile by the player and communicates the sensor data to the processing unit. The processing unit collects and analyses the sensor data to identify similar data, associates such data to a player, and stores the associated data. The sensor collects further sensor data at a second moment of time before release of the projectile by the player, which second moment of time is later than the first moment of time and communicates the further sensor data to the processing unit. The processing unit compares the further sensor data to the stored associated data to identify the player.
