Without bowling, wooden lanes would be used as basketball courts by paper-thin people and as a flat surface to fold baseball legend Mark McGwire’s shirts. Put narrow wood surfaces to good use with today's Groupon: for $6, you get two games and shoe rental for one person at Cassat's Batt Bowl (up to a $12.19 value).

Cassat's Batt Bowl's facilities lure bowlers of all ages with a plethora of smooth lanes, some of which are surrounded by bumpers, and league and specialty bowling. Roll one of Cassat's colorful, varying-in-weight bowling balls toward innocent pins while wearing stylish yet effectual nonscuffing footwear. Xtreme bowling, a cosmic-bowling experience that takes place on Friday and Saturday nights, assuages the eyes with lasers, disco lights, black lights, and fog, and doles out stimulation for the ears in the form of loud music and the sounds professional athletes make when they get injured. An arcade room and snack bar ensure those waiting to roll remain entertained and full of flavor.

Cassat's Batt Bowl offers its own deals at certain times of the week that may be better values than this deal; plan ahead to make sure you're redeeming your Groupon at the most opportune time.
