Marred by bird attacks, sand traps made from cost-cutting quicksand, and texting-induced cart accidents, golf has surpassed lava surfing and equestrian water polo in annual sports injuries. Solidify your short game in a safe indoor environment with today’s Groupon: for $10, you get $20 worth of mini golf at Kings and Knights in Half Moon Bay's Harbor Village Mall.

A round of putting ($5 per person) at Kings and Knights' always-seasonable indoor course sends golf balls through 18 labyrinthine holes of props, traps, and vibrant décor. After braving nine holes of train crossings and piratical perils, golfers arrive at the black-light room, where ghosts and cobwebs glow amid a neon loop-the-loop and fluorescent barriers that illuminate the putting path. Open seven days a week, Kings and Knights allows the busiest of friends and familiars to navigate miniature fairways, keep score with miniature pencils, and high-five with regular-size hands.
