The three holes on a bowling ball represent the three phases of bowling: windup, release, and genuflection. Send a ball properly on its way with today's Groupon to ibowl.ca Family Fun Center in Cambridge. Choose between the following options:

• For $10, you get $25 worth of cosmic bowling and mini golf.
• For $165, you get a one-hour rental of the entire bowling alley, which includes use of the mini-golf course, a pool table, and the jukebox (a $339 value, including HST).

Nestled within the walls of a former shoe factory, ibowl.ca Family Fun Center unrolls 7,000 square feet of smile-inducing recreation, from bowling and mini golf to an arcade. Amid the glow of cosmic bowling, ball slingers hurl volcanic-glass spheres down eight gleaming lanes and aim toward 5- or 10-pin sets (up to a $4.87 value for students/seniors; $7.30/game, including shoes, plus HST). An automated scoring system tracks every strike, spare, or gutter-ball, and optional lane bumpers keep balls in and invading Visigoths out. Sporting an around-the-world theme, the nine-hole mini-golf course challenges putters' resolve against obstacles such as igloos, Indian palaces, and an invisible flamingo colony (up to $3.32/round for students/seniors; $4.42/round for adults, plus HST).

One-hour alley rentals let buyers host up to 56 people and include unlimited play on all eight lanes, shoe rental for each bowler, access to the mini-golf course and the pool table, and use of the jukebox. Hosts can order off the catering menu (up to $9.50/person, plus HST), and can make a magnanimous gesture toward friends or a peace offering toward offended bowling pins.
