Glowzone: Las Vegas is out to prove that everything is more fun under blacklight. The massive indoor play space puts a cosmic spin on classic family-friendly pastimes such as mini-golf and bumper cars, but invents a few new games of its own. Bazooka Ball, for example, mixes elements of laser tag and paintball (but without the painful pellets), while a ninja course invites warriors to overcome various obstacles in the ultimate agility test. And very young visitors aren't left out of the fun—the soft city jungle gym is designed especially for those under age 7, and features slides and a twisting, turning, glowing maze.
