There are also several variations on sports games which are made portable thanks to inflatables. A sports cage is an inflatable cage that holds up a backdrop that resembles a sport (e.g. baseball, American football, soccer, golf) in which you throw, toss, hit or kick a ball at a marked spot on the backdrop. The cage not only holds the backdrop but keeps balls from flying everywhere. Some sports cages come with a radar gun that will tell you the speed of your throw or kick.
