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 $10, you get $20 worth of play on the driving ranges, mini-golf course, in the golf simulator, and in the batting cages at The Plex South on Engle Road.

The Plex South protects athletes from Mother Nature's nagging interference with a 100,000-square-foot indoor space equipped to host an array of sporting activities. Hit the batting cages ($2 for 12 pitches) to pound out screaming line-drives and griping grounders on one of three speeds of baseball pitching, or take on slow-and fast-pitch softball to aim at even bigger spheroids with even worse attitudes. An 18-hole indoor mini-golf course ($5.50/round; discounts for kids younger than age 10 and for groups) challenges putt-putters of all ages with water hazards and rough, while a golf simulator ($25/hour) allows players to experience the game the way 12th-century Scottish computer scientists intended. A 30-station, 100-yard indoor driving range ($5.50 for a small bucket of balls) provides further opportunity to bully golf balls without the distracting din of high-speed cart crashes ruining your backswing. A 240-yard outdoor range ($4.50 for a small bucket) is also available for those using solar-powered drivers.

Its climate-controlled climes keep The Plex South comfortable, regardless of the decisions made by all-powerful meteorologists, and 65-foot-high ceilings make the facility accessible to all but the very tallest golfers. Sport-fatigued game-players can avail themselves of an on-site concession stand (not covered by today's Groupon) to fuel their athletic achievements and trade confidence-shattering smack talk. The Plex South is open every day of the week, providing ample opportunity to use today's deal to hone your putting prowess or intimidate coworkers with the power of your mighty eight-iron.
