Abstract: An elongate blow gun defined by a tubular barrel, with a concave resilient entrance ring receiving in a sealing relationship a dart member therewithin. The dart member, through pneumatic pressurization by an individual, directs the dart member as a projectile towards a target board, including alternating and contrasting target sections thereon. A modification of the invention includes a dart member defined by triangular stabilizing vanes that in a first position position each hypotenuse edge of each stabilizing vane in contiguous communication against a conical side wall surface of the dart member that pivots rearwardly upon ejection of each modified dart member from the barrel to enhance stabilization of the dart member during its trajectory towards the target board.
