SlamBall is a trampoline-powered sport that mashes basketball, gymnastics, and full-contact hockey-style physicality into one gravity-defying package. Players launch off in-court trampolines to throw down dunks that would be impossible on a normal court, making it a favorite highlight-reel sport even though it has never quite broken into the mainstream.
Here's a look at where SlamBall came from, how the game is actually played, and what has kept it alive through multiple TV comebacks.
SlamBall was created by Mason Gordon, who began testing the concept on a makeshift trampoline court in a Los Angeles warehouse around 1999-2000.
Gordon secured a television deal in 2002 with The National Network (TNN), which rebranded as Spike TV the following year, giving SlamBall its national TV debut.
TV producer Mike Tollin, known for shows like Coach Carter and Smallville, helped Gordon get SlamBall's first broadcast off the ground.
SlamBall is played on a specially designed court with trampolines, called springbeds, embedded in the floor in front of each hoop.
Teams field four players at a time on the court.
Slam dunks are worth three points, while regular baskets made without using a trampoline are worth two points.
Defenders are allowed to use the trampolines to contest shots and block dunks at the rim, a legal form of goaltending unique to the sport.
A standard SlamBall game consists of four quarters of roughly five minutes each, not the longer quarters used in basketball.
The three core on-court positions in SlamBall are handler, gunner, and stopper, though teams can mix and match them across their four players.
The handler is the primary ball handler and playmaker, similar to a point guard in basketball.
The gunner is the primary scoring threat, typically the player attacking the rim for high-flying dunks.
The stopper is the main defensive specialist, tasked with protecting the rim from attacking players.
SlamBall's original TV run lasted for two seasons in the early 2000s before it went on hiatus.
The sport has resurfaced periodically since then, including a publicized attempt at a broadcast revival in the 2020s.
SlamBall's blend of basketball scoring with football- and hockey-style contact set it apart from other trampoline sports of its era.
The sport has influenced pop culture and inspired amateur pickup leagues, even though it has never achieved mainstream, year-round league status.
