Golden Road and Give or Keep were the only two where the game was fully exposed (defined as "the game's name being visible") before the item up for bids. Note that this is no longer true, as these days, the stagehands set up all of the Golden Road decor during the bidding on the item up for bids.
Grand Game, Check-Out, and Trader Bob are/were slightly taller than the giant price tag (although I think Check-Out might be set far enough back that you can't see it on camera?). For Grand Game, the show eventually started setting the tag to hover maybe a foot off the ground to conceal the top of the big flashing dollar sign.
Depending on where you're sitting in the audience, you might be able to see what's behind the giant price tag just because it isn't very effective at concealing games at angles other than the angles the cameras are at.
The signs for Now or Then and Master Key used to stick up higher than the top of the turntable wall, so if you knew their shapes, you could tell they were coming up. However, you wouldn't necessarily know in which act, because the games would be set as soon as the space became available, even if they were multiple acts away.
But maybe those two fall into the same "Does it count if you have to know what to look for?" category as things like the earliest days of the Plinko sign, when it would be set in the back of the audience but it wouldn't display "Plinko" during the come on down.
