My prediction: Gridlock is going to be Split Decision II. Maybe Squeeze Play-ish, that you get a couple cars out of the way so that the remaining cars can move and reveal the right price. Like Split Decision without a secondary prize. The second picture seems to be in the part of the game where the cars are moving into position.
I assume it's a car game, because upon super-zoom the punctuation in question on the scoreboard almost definitely appears to be a comma. Have we had any $30,xxx priced cars on the show lately?.. Though, a zoom in on either picture doesn't seem to (clearly) show any particular numbers on the cars. Granted, it's hard to see anything in detail with this resolution, but I couldn't make out anything specific.. And there doesn't seem to be a small prize/ grocery item podium anywhere nearby either, so there's that. I think it's a quickie-ish Car Game.
Hey, but maybe they're replacing Stack the Deck. In theory, just looking at these screencaps, one could assume that they've created another "We'll give you 7 possible numbers in the price of the car but you have to eliminate 2 of 'em" type of game. That can be made extra hard but the little cars might make it entertaining enough that it might not be considered too "evil"..
Looks like fun though. We'll see Monday.
