Sports played with spheres are easier to master than rectangular sports, such as Rubik's cubing and throwing bricks into windows. Circle fun with today's Groupon: for $24, you get three hours of bocce for two at BocceNation (a $48 value) at the Hilton Palm Beach Airport.

BocceNation entertains families and competition junkies with all-ages fun, fitness, and outdoor exercise on peaceful lakeside bocce courts. Situated on the luxurious grounds of the Hilton Palm Beach Airport hotel, BocceNation's courts contain all the game's required equipment including balls and a patented measuring device that precisely quantifies distances and doubles as an inseam measure to help accurately tailor team jumpsuits. For three hours, two bocce-ball wielders divide into teams, throwing smooth orbs as close to the mark as they can, competing to outdo the other team in accuracy, much like bowling. A colorful scoreboard tracks points while multitasking as a beverage holder for soda, cold beer, or mac 'n' cheese smoothies. Easy access to the lakeside tiki bar lubricates throwing arms with liquid confidence, and experienced staff members stand by to confer with new players about bocce rules and regulations.
