Bowling-alley lanes are covered in a thin layer of oil, facilitating a smooth trip for the ball and hilarious pratfalls for would-be pin burglars. Engage in slippery sport with today's Groupon: for $20, you get a bowling outing for up to five people at Center Bowl (up to a $41.25 total value). The package includes:

• One hour of bowling for up to five people (up to a $20 value)
• Up to five pairs of bowling shoes with socks (a $4.25 value/person)

This Groupon is valid during all open bowling times.

Center Bowl beguiles bowlers with 30 lanes, themed pin-toppling events, and more than 50 years of strike-slinging history. Highly polished lanes pander to snazzily shoed patrons with automatic touch-screen scoring systems that effortlessly tally triumphant strikes and intercept top-secret messages from pin insurgents. Beginning bowlers ease into the art of the two-fingered, one-thumb ball toss with lane bumpers, which direct orbs toward expectant pins by covering misdirecting gutters. A midlane stage beckons balladeers during karaoke bowling on Wednesday evenings, which encourages guests to try hands at cadenced crooning in exchange for a free game pass. Thursday night carnival bowling bestows prizes upon bowlers who depose colored pins, and a semiweekly Thunder Alley light show permeates lanes with neon light, fog, and lucky, three-holed balls on Friday and Saturday evenings. An assembly of 16 flat-screen televisions display music videos above the lanes, entertaining waiting bowlers and inspiring poststrike victory-dance choreography.

Center Bowl's rates fluctuate throughout the week, so plan ahead to ensure you get the best value from your Groupon.
