Like joggers crossing a highway, bowlers should avoid nearby bumpers and resist the temptation to chase wayward balls into neighboring lanes. Roll carefully with today's Groupon: for $9, you get a bowling package (up to a $19.15 value) at Sunset Lanes in Beaverton, valid during open-play and cosmic bowling. The bowling package includes:

• Two games of bowling (up to a $9.90 value)
• One shoe rental (up to a $3.25 value)
$6 arcade FunCard

Sunset’s slick wooden bowling lanes have hosted pin-splitting matches for more than 40 years. After slipping into rented bowling shoes, players can sling their three-holed orb down one of 36 well-slicked alleys equipped with computerized scoring systems as precise as the ones used in Olympic binary-coding competitions. Cozy sofas encircle select lanes, and sizeable high-definition TVs suspend from ceilings to broadcast scores and Emmy-nominated turkey animations. After bowling, head over to the ample-sized game room to compete for prizes over digital incarnations of Wheel of Fortune and Deal or No Deal or duke it out over physical challenges such as NBA Hoops or Guitar Hero. The arcade’s reloadable FunCards digitally store tokens and tickets so that, that like high-powered stock brokers, youngsters can easily exchange their tickets for stuffed animals at the end of the day. Sunset Lanes 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.
