The 2,000-square-foot laser-tag arena at Shotz Lazer Tag & Billiards swallows up to 24 players in its black-lit barricades, spitting them out for tests of manual dexterity in the arcade and at pool tables. During games of tag, laser beams slice though a shroud of fog and hearts race in time to pumping music. The staff not only explains the rules of laser tag and equips players with gear, but periodically reconfigures the terrain to prevent frequent visitors from gaining a home-field advantage. Marksmen receive scorecards documenting the number of shots fired, their accuracy, and the location of any stains on their shirt after emerging from the black light. Nearby, the arcade rings with electronic yelps emitted by the gaming machines, and the crack of cue balls echoes over the felt of 9-foot Gold Crown pool tables.
