The series is produced by Talpa Studios and the Eureka Productions division of Fremantle, and hosted by Jay Pharoah.
This game show is the adaptation of the Dutch TV series De kwis met ballen.
Although Pharoah and the contestants are American, the show is actually produced and filmed at Docklands Studios in Melbourne, Australia.
Six giant numbered balls are placed at the top of a set of parallel ramps leading down to the edge of a swimming pool.
They must choose one answer at a time and stand at the bottom of its ramp as the ball is released.
