Players get out of play when they are hit by small spherical gelatine-filled rubber balls called paintballs. The paintballs break out and marked the cloth brightly. It is out of debate whether it is hit by an enemy or a friendly player. In both cases, the player gets out of the game.
Never try to rub paint from your paint otherwise you will be punished. Take this game as a source of fun never have to be very serious about this.
