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: for $27, you get two hours of bowling and shoe rental for up to six people, plus a soft-drink pitcher, at Bowl-a-Roll Lanes (up to a $61 value).

Bowl-a-Roll Lanes has purveyed the sporting side of pin punishment for more than half a century, hosting bowlers of all ages and skill levels on 32 automated lanes. Upon arrival, customers will lace up their dual-tone shoes and slide over to the ball rack to pick out their globular weapon of choice. Two hours will spin away across lacquered wood slats as teams of up to six bowlers channel their focus and energy into subsequent frames of pin scattering, breaking concentration only to restock caffeine levels from the soft-drink pitcher. Children may boldly bowl with the bumpers up to prevent gutter anxiety. Though not valid with your Groupon, groups may also stop by Bowl-a-Roll on Friday and Saturday nights for cosmic bowling, a black-lit laser light show that allows players to experience the game the way its creator, George Lucas, originally envisioned it.

Every day of the summer, Bowl-a-Roll offers children one free game of bowling and shoe rental as part of the “Say No to Drugs, Say Yes to Bowling” program. Schools from around the greater Rochester area collaborate with Bowl-a-Roll to give kids a safe and fun alternative to dangerous substances that doesn't involve rappelling off the town hall.

Although Bowl-a-Roll Lanes sometimes offers a discounted rate online, this Groupon still offers the best deal available.
