When most people talk about what goes into a great party, they usually mention something about that certain indefinable something, often referred to as the X factor. Residents of Harrisburg, IL have their own recipe for fun, one that relies on an even stronger ingredient: the Z Factor. At this sprawling adventure center, groups celebrate birthdays, graduations, and more of life's big occasions with three activities as distinct as they are exciting. Read on to learn more:

• Trampoline: Billed as "the largest trampoline park in the tri-state," the trampolines at Z Factor take up a massive corner of the warehouse-like space. In addition to an open jump area, the trampoline park also includes spaces for bounce-aided games of dodgeball, volleyball, and basketball. There are also foam pits (including one just for kids) where jumper can practice their most ostentatious landings.
• Ice Skating: No matter the season, skaters can practice their most elegant twists and twirls on Z Factor's synthetic-ice rink. Like any good skating routine, there's also plenty of invigorating music, as well as laser lights that add a touch of drama to each lap around the rink.
• Paintball: Spread across nearly two acres, Z Factor's paintball fields give players ample room to move, plot, and hide during rounds of splatter-filled combat. The park also offers a paintball shooting range for players looking to improve their accuracy.
