(I'm going to argue that bombarding the panelists with clues and slime gave "Figure It Out" physicality.)
I wouldn't even go that far, citing Make the Grade, Get the Picture and Nick Arcade as games where the moving about wasn't the point but the means to get to a new event or back to home base. Yes, Arcade had the green screen round, but other'n that, nothing.
The "trademark" (such as it is) is that the network was putting on game shows specifically for kids; that they can watch and play along with and enjoy. Not adult game shows taking two weeks at Christmas, Easter and summer break to feature young players in a watered-down version of the game, but game shows that were designed specifically for youth consumption.
