The time is a bit odd considering 25 Words has a nice afternoon slot, but I think it fits in well with what GSN is apparently trying to accomplish. Fun, light-hearted daytime games for low stakes with some play-along value. And it's not taking a slot occupied by another game.
Wouldn't be surprised if this is the first exposure to the show for many people. It aired at 10:30 am for a while here, but I wonder how many stations aired it in the middle of the night along with all the other Byron Allen shows?
