Description extrapolated from TheBigGameHunter.com:

ZULU BLOW GUN GAME (1925, Zulu Game Co., Battle Creek, Michigan) comes from a category of games no longer available: the "projectile" game. Safety requirements have virtually eliminated all sharp, pointed projectiles from games (other than DARTS), and although the packaging on the ZULU BLOW GUN GAME states "harmless," the game's bamboo dart, when made airborne from the blowgun, could pierce many things, including body parts. Object was to score points by hitting different valued targets using the blowgun and bamboo darts.
