Abstract: A portable, “design-your-own course” miniature golf game utilizing replica golf greens, plastic or rubber tees and balls for play at beaches, lakes or where large sandy areas are available. Players design and build their own course in the sand using implements provided with the game. The game is played by alternately using one's thumb, index or middle fingers to thump (“hit”) the ball in a desired direction or trajectory. The game is based largely on the conventional rules of golf, with specific regulations addressing hand and finger positions and striking techniques for putting the ball in play. Game implements, along with a water-resistant score card and rule book, are packaged in a lightweight, collapsible bag designed to resemble a golf bag.
