The dimples on a golf ball help it fly farther with greater accuracy, just as the dimples on a baby help it steal candy from gullible strangers. Find your adorably sporty sweet spots with today's Groupon at the Golf Dome at the Robert Morris University Island Sports Center. Choose between the following options:

• For $14, you get three medium buckets of 70 range balls each (up to a $28.50 value).
• For $79, you get four one-hour group golf lessons (a $139 value).

Boasting one of the longest uninterrupted shots of any indoor golfing facility in the country, the Golf Dome furnishes driving-range denizens with expert instruction and adjustable hitting conditions in a comfortable environment. Beneath the inflatable roof, chip-shot champs bask in balmy 70-degree air and launch miniature moons into orbit from 42 stalls, while two types of artificial surface simulate tighter or grassier lies. After exhausting the 70 balls in each medium basket, players can display their putting prowess on the practice green, or reenact the Battle of Sand Bunker Hill while honing their wedge shot skills.

During the four hour-long group golf lessons, PGA professionals and former LPGA tour players teach the fundamentals of the game. Sessions are geared toward the beginner, ensuring students receive instruction on game essentials from swing technique and the short game to proper etiquette at the blue, white, or afternoon tees. The Golf Dome is open seven days a week, but hours vary daily; check the schedule here.
