Humans have been putting spherical objects in hoops for centuries, but until the invention of the dunk, the fast break, and face dribbling, it wasn't an activity worth watching. See if "basketball" lives up to the hype with today's Groupon: for $5, you get one general-admission ticket to any Las Vegas Aces 2011 regular-season or playoff game at the Sport Center of Las Vegas (up to a $10 value). Students and military who bring their IDs can get in for $3.

Watch the scoring frenzy of the American Basketball Association’s Las Vegas Aces as they battle their next opponent in the family-friendly confines of the new Sports Center of Las Vegas. The high-flying and sharpshooting Aces have regularly racked up 100-plus points per game en route to an 8–1 record while their fans are averaging three ketchup stains per hot dog. Basketball buffs can cheer on speedy 6-foot guard Michael Johnson, who commands the team with more than 20 points per game.

Founded in 1999, the current American Basketball Association features looser rules that are designed to fuel a more audacious and dazzling offensive style of play.
