I think they are all pilots. Aside from the unsold shows, the ones that went to TV all look like they are from pilots. Both "Match Game" clips are pilots, as was LMAD. Also, look closely at the "Double Dare" clip. There was never a time the isolation booths didn't have the red and green designs on their back walls on the actual series. I've seen snippets of the "Now You See It" pilot, and the game board stayed the same into the series, so that may also be from the pilot. Fremantle certainly has a number of pilots to choose from, so hopefully this will last a while.
