That's the irritating thing. When Challenge aired other programming that wasn't gameshow related for e.g sports TNA Wrestling, poker or that one time they aired football in late 2020, that still fitted the actual challenge element of the channel while still branching out. The only challenge with Cash in the Attic and Real Deal is watching it without falling asleep as far I'm concerned.

The 'challenge' is quite obviously to raise as much cash as possible by selling stuff from someone's home; with the aim of achieving enough to do something (usually incredibly run-of-the-mill).
