Mini golf’s popularity has naturally led to a host of miniaturized copycats, including toeball and nano-marbles, which is played inside a particle accelerator. Engage in the most timeless shrunken sport with today's Groupon: for $12, you get two 18-hole rounds of mini golf for two at Pirate Mini Golf in Marion (a $24 value).

Phosphorescent borders hem the black alleys of each hole at Pirate Mini Golf’s 18-hole course, where walls adorned with murals of ocean waves and skulls and crossbones coalesce to form an inventive, pirate-themed pastiche. As putter-wielding duos traverse the black-lit landscape, balls must pass through lighthouses, roll over steep slopes, and immunize themselves to scurvy on their passage to each vividly glowing neon hole. With today’s Groupon, duos can tap their way across the black faux grass two times over for a 36-hole odyssey before retiring to the lounge to watch fellow patrons croon through karaoke or discover the latest cat-celebrity news by harnessing the putt-putt emporium’s free WiFi.
