Carol Vorderman presents an eight-part series, putting the nation's brainpower to the test.

Two teams - led by captains Sara Cox and Rufus Hound, with a celebrity and a studio audience guest - compete over five rounds, each specifically designed to stimulate a different part of the brain, to demonstrate whether contestants are right or left-brain dominant, logical or creative, analytical or intuitive.

Round one is problem-solving, round two tests spatial intelligence, round three tests memory, round four looks at code-breaking and round five is the quickfire round. The players must also reconstruct fragmented images from a large heliopad, all in the hopes of winning £10,000!
