The three holes on a bowling ball represent the three phases of bowling: wind-up, release, and genuflection. Send a ball properly on its way with today's Groupon to Jewel Lake Bowling Center. Choose from three package options:

• For $10, you get two games of bowling each and shoe rental for two people (a $26 value).
• For $25, you get a two-hour lane rental and shoe rental for up to six people (a $64 value).
• For $60, you get an extreme-bowling party package—valid Thursday nights and Sunday afternoons—that includes a 2.5-hour lane rental and shoe rental for up to 12 people (up to a $168 value).

At Jewel Lake, home to Professional Bowlers Association Masters winner Sean Rash, armies of pins stand ready to fall as posses of patrons hurl spheres down its friction-fighting lanes. A little friendly competition breaks the ice in any potentially awkward social situation, from introducing significant others to parents to accidentally releasing a ball backward at a group of coworkers. During extreme bowling, a live DJ serenades strikes and spares on Thursday nights and Sunday afternoons as kickball teams and troupes of toddlers hone their skills beneath black lights that illuminate futuristic light shows and lingering fog. Although not included in today's Groupon, groups can fuel pin knockouts at the alley's café or peruse the pro shop for bags, gloves, or prank bowling balls that double as Chinese finger traps.
