Here's an idea (I think it could be a fit on GSN): remake Spin-Off, but the way I think it should have been done the first time - Gambit/High Rollers style.
That is, something like this:
Two couples (or just two contestants, if you prefer)
Host asks a question; whoever gets it right gets to roll the dice - there are five dice of different colors (either "electronic" dice, which don't have a habit of ending up leaning on each other and requiring re-rolls, or actual dice, with a "Let 'Em Roll"-style ramp between the contestants).
The first time per game, they roll all five dice; after that, they can choose which dice to keep and which to roll (yes, like Yahtzee - and no, I never saw that game show).
After a roll, if the couple is ahead, they can freeze; the other couple needs to answer questions to get to continue to roll, until either (a) they miss a question and lose the game, or (b) they get a better "hand" than the opponents and win.
In order to fit it into a half-hour, it would be an "as many games as we can play before time runs out" format (similar to pretty much every syndicated version of Hollywood Squares), followed by some end game.
